The central business district (CBD) is the inevitable product of economic development to a certain stage, and it has become the most important driver of economic growth in a city or a country. The formation process of the central business district itself is the process of changing the regional spatial structure. The agglomeration and dispersion of economic activities in space form agglomerations of various industries. Regional economic activities thus form dense and sparse areas in space. The area of intensive economic activity becomes the central area, and the sparse area becomes the peripheral area. Therefore, the central business district is the core area of the regional space, and it is also a special expression of the regional spatial structure. Over the past 40 years of reform and opening up, industrialization and urbanization have boosted the rapid development of China's economy. The differences in regional development have become increasingly obvious, and the overall spatial pattern of "high in the east, middle in the middle, and low in the west" has emerged. The development gap between urban and rural areas is also widening, and the economy presents a dual structure in space. With the rapid development of urbanization in China, the central business district is booming, and all kinds of cities are vigorously building central business districts. Famous CBDs such as Lujiazui Financial District and Beijing Central Business District have emerged. From the perspective of China's reality, there seems to be some kind of internal connection between the development of the central business district and the changes in the regional spatial structure. Then, through which paths does the central business district affect the regional spatial structure? This paper will conduct an in-depth analysis on three levels: micro, macro and meso. That is to analyze the impact mechanism of the central business district on the regional spatial structure from the perspectives of micro-cosmic residents and enterprise location, regional spatial form and network structure, industrial structure and specialization, and transportation network structure.
Before expounding the influence mechanism of central business district on regional spatial structure, it is necessary to define the concept of regional spatial structure in this paper. At present, there is no authoritative and unified definition of the concept of regional spatial structure in academic circles. From the perspective of geography, regional spatial structure can be expressed as the characteristics of physical structural units such as rivers, lakes, rivers, and mountains. This paper argues that regional spatial structure is essentially the expression of economic activities in space, and economic activities are manifested in the location selection of residents and enterprises, industrial spatial layout and regional specialization, transportation network, spatial organization form and network connection structure, etc. The micro-individuals of the regional spatial structure are caused by the location selection of residents and enterprises. On the one hand, the spatial location selection of residents and enterprises will cause spatial differences in consumer demand, commuting distance, product transportation costs, and transportation networks; on the other hand, The result of site selection by residents and enterprises will be manifested as the spatial state of separation or integration of residential areas and industrial areas, which itself is the most intuitive expression of regional spatial structure. The regional spatial structure not only shows the spatial agglomeration and dispersion of elements and industries within the region, but also includes the external form formed between regions, because there are economic and social connections and spatial spillover effects between regions. The position and function of a single region in the overall regional spatial structure and the function it undertakes have an important impact on the economic and social development of the region. For example, there are central cities and secondary cities in an urban agglomeration, and the relative numbers and relationships between the central cities and secondary cities constitute the spatial structure of the urban agglomeration. For the central city, other secondary cities are "peripheral areas". Changes in the economic spatial structure within a region will also have a certain impact on the economic and social activities of adjacent regions, which in turn will cause population, enterprises and industries to be reconfigured between the local area and adjacent regions, resulting in differences in the speed and scale of development between regions , manifested as changes in the relative economic relations between regions. Therefore, this paper believes that the regional spatial structure can be manifested in six aspects: the location selection of residents and enterprises, industrial spatial distribution and specialization, traffic network structure, regional spatial structure form, and urban network structure. Industrial spatial distribution and traffic network structure are from the middle-level perspective, while regional spatial structure and urban network structure are from the macro-level perspective. In particular, it should be noted that this paper does not divide the spatial scale of the regional spatial structure in terms of connotation, because the region itself is a spatial category. From the perspective of geography, the internal spatial structure of a region is composed of several sub-regions. From the perspective of multiple regions, a single region is a sub-region that forms a higher-level region.
1. The influence mechanism of the central business district on the location selection of residents and enterprises
(1) The impact of the central business district on the distribution of residents' living space
One of the important manifestations of regional spatial structure is the distribution of residents' residences. As consumers and product demanders, residents' choice of residence will directly affect the location selection of enterprises and the commuting structure of the region, which in turn will affect the regional spatial structure. . As the area with the highest land and real estate prices in the region, the central business district is also the area with the highest quality infrastructure and social public service resources. The life convenience of residents in the central business district and neighboring areas is relatively high. The completion of the central business district will often have a premium effect on the land function and land price in the adjacent area, and will also cause enterprises to bear higher business costs. Factors such as infrastructure, public services, and living convenience are important factors affecting urban housing prices. The completion and development of central business districts are important factors for land functions and housing prices in adjacent areas and cities, and land functions and housing prices are factors that affect residents' purchase of houses. important influencing factors. This paper considers only the following aspects:
First, the land premium. The completion of the central business district will directly increase the land price in the adjacent area, so the land supplier (local government) can sell the land at a better price in the process of attracting investment, and the land owner and real estate owner will have higher rent expectations . The premium of land prices and rents will also promote the transformation of land functions. For example, the central business district gathers a large number of modern service industries, forming a large demand for related supporting industries in adjacent areas, such as warehousing, logistics, food processing and other industries. The incentives for the transformation of commercial land to commercial land functions have increased, and the functions of commercial land in adjacent areas have been continuously improved. The increase in the proportion of land with commercial functions has increased the land appreciation space of residential areas to a certain extent.
Second, the real estate premium. The completion and development of the central business district will directly form a premium for real estate in adjacent areas. Specifically, the closer to the central business district, the higher the housing price. Housing prices are the core factors that directly affect the location of residents' residences. Consumers (residents) make certain trade-offs between living convenience, comfort and commuting distance. The closer to the central business district to buy or rent a house, the better With high living and transportation convenience, you can enjoy the best public service resources and convenient transportation in the whole region. The closer you are to your workplace, the lower the commuting time cost. Consumers who buy or rent houses in areas farther from the central business district can enjoy relatively lower housing prices and rents, but must bear longer commuting distances and time costs. How to choose the final place of residence depends on the consumer's income status and preferences for living convenience and commuting costs.
Thirdly, elements and public services gather. As a region where various factors and public service resources are highly concentrated in the central business district, the rate of return of various factors including labor is relatively high, the degree of sharing of public services is higher, and the per capita cost of public investment is relatively low. The labor force can obtain higher wages, and the central business district will attract a large number of laborers to gather. The central business district will cause higher employment density and residential density, thus forming consumer demand for products. From the perspective of the whole province, the central business district will become a regional The area with the highest economic activity density and residential density.
(2) The impact of the central business district on the spatial distribution of enterprises
The location selection of enterprises is also the basic driving force for the change of regional spatial structure at the micro level, and the spatial transfer of enterprises is the reason for the formation of the spatial distribution of enterprises. The central business district is a highly concentrated area of various service industry enterprises. The construction and development of the central business district is the core area in the regional spatial structure and the economic growth pole of the region. It is itself a specific form of spatial structure. Changes in the number of enterprises in the business district and changes in the industry to which the enterprises belong will cause changes in the overall regional spatial structure. This paper argues that CBD has at least the following mechanisms for the influence of corporate location selection:
One is agglomeration externalities. The agglomeration of a large number of enterprises is conducive to exerting the externality of the agglomeration economy. Marshall's externality believes that sharing, matching and learning are the spillover mechanisms of the agglomeration economy, and enterprises in the central business district can fully enjoy these three effects. The central business district gathers a variety of service industries, which is conducive to sharing commercial infrastructure and various industry information, sharing new technologies, and sharing a rich factor market. The central business district gathers various high-quality factors including labor force and capital. A large number of concentrated enterprises provide jobs for different types of professionals. Various financial service institutions provide investment platforms for venture capital. Enterprises can use financial services to The platform obtains financing and capital is optimally allocated. A large number of enterprises gather in the central business district. The geographical proximity makes it easier to communicate within the industry, and it is easier to generate new ideas and innovations. It also provides convenience for mutual learning and knowledge overflow among enterprises. Therefore, the CBD is the sector with the largest Marshall externality in the region. In order to maximize the Marshall externality, a large number of enterprises (especially business service enterprises) gather in the CBD, and the CBD becomes the spatial agglomeration center of regional business service enterprises. The center-periphery gradient distribution is formed between sub-regions in other regions.
The second is local market effect, price index effect and crowding effect.Enterprises are the main body of economic activities. New economic geography believes that the spatial distribution of economic activities mainly depends on agglomeration (centripetal force) and dispersion (centrifugal force). These two opposite economic forces are mainly manifested in three aspects: the local market effect , price index effect and crowding effect. This paper will focus on the analysis of the impact mechanism of the central business district on the regional spatial structure through the above three effects. The local market effect believes that under the condition of increasing returns to scale, the output scale of the area with larger demand scale is also larger. In order to save transportation costs, enterprises continue to approach the central market to fully obtain various externalities of agglomeration. Another manifestation of the local market effect is that regional output grows faster than the number of firms. As the central market of the region, the central business district attracts enterprises in neighboring areas through the local market effect. Adjacent enterprises continue to move to or approach the central business district. The number of enterprises and the output value of enterprises in the central business district continue to increase. As a result of spatial changes in the number of enterprises and output value in the regional space, the central business district becomes a highly concentrated area of the number and output of regional enterprises, forming a central and peripheral spatial structure with adjacent areas. The price index effect believes that due to the relatively large number of local enterprises, local residents can consume more types of products, enterprises can obtain various raw materials and intermediate products at lower costs, and the quantity and types of products that need to be purchased from other regions are equal. At the same time, the transportation costs are lower, so local residents can enjoy lower living costs and higher real wages, and it is easier to attract more residents and labor. For enterprises, the advantages of choosing a location in the central business district are: on the one hand, they can obtain various externalities and local market effects of the agglomeration economy; on the other hand, they can also obtain cheaper raw materials and intermediate products through the price index effect. Save product transportation costs. The area where the central business district is located has more government public service resources, which can handle various administrative procedures more efficiently and save time, and it is also easier to obtain various preferential policies from the government. The crowding effect believes that due to the local resource and environment carrying capacity, market size and fierce competition among enterprises, some enterprises choose to transfer to other regions. Enterprises in the central business district have fierce competition, high rents, high business operation costs, limited industry scale and capacity, and some enterprises with weak profitability choose other regions. Therefore, most of the enterprises left in the central business district are enterprises with strong profitability, and enterprises with relatively weak profitability choose other regions for production. Obviously, the crowding effect leads to the relocation of enterprises in the CBD to adjacent areas to a certain extent, causing changes in the spatial distribution of the number of enterprises in the region, which is a kind of
To sum up, the central business district affects the spatial location of enterprises and then affects the spatial structure of the region through the agglomeration externality, local market effect, price index effect and crowding effect. The local market effect and price index effect will attract more enterprises to agglomerate Cause the scale and agglomeration of the central business district to increase. The crowding effect makes the central business district gather the most profitable enterprises within the region, which in turn makes the economic output density of the central business district higher. Therefore, there are differences in the relative magnitudes of the three effects in different development stages of CBDs: assuming that the overall regional demand and market size are constant, in the initial stage of CBD development, the number of CBDs within the region is small, and the local market effect and The price index effect plays a dominant role, and the crowding effect is relatively small; in the mature and degraded stages of the central business district, due to the increase in the number of central business districts within the region, the crowding effect will play a leading role.
2. The influence mechanism of central business district on urban industrial spatial distribution, industrial structure and specialization
The spatial distribution of industries is also an important manifestation of the regional spatial structure. The agglomeration of enterprises forms industrial agglomerations, and the spatial concentration of industries forms agglomeration areas and dense areas. As a highly concentrated area of modern service industries, the establishment and development of central business districts have an important impact on regional industrial development and regional specialization. Specifically, it can be divided into the following effects.
First, the local market effect. As the central market of regional elements and commodities, the central business district gathers a large number of service enterprises. A large number of enterprises are constantly approaching the central business district in order to obtain local market effects. Enterprises with different profitability choose locations far away from the central business district. Different distances, so from the perspective of space, the distribution of enterprises will form enterprise clusters with different circle structures with the central business district as the center. The larger the scale and the number of enterprises in the central business district, the larger the spatial scope of the circle structure and the greater its ability to radiate externally. Therefore, the central business district has become the region with the highest degree of regional service industry concentration, as well as the region with the largest output scale and number of enterprises in the tertiary industry.
Second, the industry association effect. From the perspective of industrial association, the central business district is a dense area for many corporate headquarters, regional headquarters, and R&D and design departments. Industries such as finance, technology, consulting, retail, logistics, law, accounting, exhibitions, business, and culture are more concentrated. With high human capital and strong industrial correlation, these industries are more likely to have forward and backward connections with other industries, forming a complete industrial value chain, which is conducive to promoting the development of other industries, and other industries will benefit from the industrial overflow of the central business district effect. The industrial spillover effect will attract more industrial service industries and service industry clusters in the central business district. Therefore, the level of industrial agglomeration in the central business district and its surrounding areas will continue to increase, and the level of industrial agglomeration and the proportion of service industries in the entire region will continue to increase. The industrial structure of the whole region tends to be optimized. The CBD headquarters economy has strengthened the connection of the regional industrial value chain. The CBD has become the allocation center of elements and resources, forming a control over the regional industrial spatial distribution and industrial structure. The industries in other areas of the CBD are highly related to the industries in the CBD.
Third, government policy support. With the advent of the service economy era, the role of the central business district in promoting the local economy has become increasingly prominent, and more and more attention has been paid to the central business district in various places. The central business district is an important display window for the achievements of regional economic development, and the central business district is even more It is easy to obtain various preferential policies, such as tax relief and guidance fund support, etc. As a cluster of regional service industries, the central business district is also an important engine for the transformation of regional economic development and the upgrading of industrial structure. The development of the central business district, especially the development of the service industry plays a very important role in optimizing the regional industrial structure.
Fourth, the specialization of agglomeration. One of the reasons why the central business district can gather various elements is that it can obtain a higher rate of return, and specialization is an important way to maintain competitiveness and profits. From the perspective of agglomeration economy, the gathering of a large number of enterprises is conducive to communication and knowledge overflow, and is conducive to the formation of industrial specialization. The agglomeration of enterprises in different industries is conducive to technological and innovation cooperation in the industry, and is conducive to the use of various externalities of diverse agglomeration. Land prices, rents, and labor costs in the central business district are all high, so various elements must maintain high marginal productivity to ensure profits, and specialization is the way to increase the marginal productivity of elements.
Fifth, market competition and specialization. The center-periphery theory holds that there is strong market competition among enterprises in the economic agglomeration area, and only enterprises with strong profitability will eventually stay. Therefore, enterprises in the central business district must have a high degree of specialization to avoid migration to secondary centers . From the perspective of regional differential development, forming a good professional division of labor within the region is one of the important prerequisites for optimizing the regional spatial structure. Different regions within the region develop their own advantageous industries to determine the specialized regional division of labor. Most of the central business districts are concentrated in regional specialization and advantageous industries, which is conducive to improving the overall professional division of labor in the region and establishing the differentiated functions of each region.
3. The impact mechanism of the central business district on the spatial structure of the regional transportation network
The transportation network of regions and cities has become the physical path of economic activities. The accessibility of transportation is an important factor affecting the travel of residents and the production and operation activities of enterprises. The network and transportation network structure affect the direction and intensity of the flow of regional elements to a certain extent. The setting of public transportation stations in the region, the planning of the road network and the construction of public parking infrastructure directly affect the evacuation capacity of the flow of people. The efficient and convenient transportation network has already Become an important embodiment of regional and urban competitiveness. As the core area of the region and the city, the central business district has a certain impact on the regional traffic network structure. The specific impact is manifested in the following aspects:
First, commuting needs. The central business district directly affects the commuting demand in the region, and the commuting demand is an important reason for the spatial difference in the intensity of economic activities. The central business district is a densely populated area of regional enterprises and populations. There are many types of commercial buildings, and various types of commercial activities gather together, such as retail, catering, accommodation, leisure and entertainment, cultural industries, etc., attracting a large number of passenger flows, which will cause large Therefore, the subway and bus lines in the central business district are dense, and the demand for underground parking spaces is large. In addition to attracting the local population, the central business district can also attract a lot of traffic from the adjacent area. Therefore, the flow of people from other regions attracted by the central business district will also generate greater demand for regional external transportation, such as expressway, intercity rail transit and other transportation methods. Because of the demand for commuting and related infrastructure, the establishment and development of the central business district will directly affect the urban planning. It is very important to reserve sufficient transportation network space in advance for the development of the central business district.
Second, commuting distance. The location of the central business district directly affects the commuting distance within the region. According to the above, the central business district will have an important impact on the location selection of regional residents and enterprises. A large number of enterprises gather in the central business district to form a job cluster, while the land price and rent of the central business district make residents choose relatively far away. The place of residence, which causes the spatial separation between the residents’ place of residence and the place of work, thereby increasing the commuting distance of residents. The change of the commuting distance within the region will affect the spatial distribution of economic activities. For example, with the popularity of private cars, the commuting distance increases. The increase makes the spatial scope of residents' consumption activities larger.
Third, commuting efficiency. As a regional transportation hub, the central business district will have an impact on the commuting efficiency of the region. The transportation network system in the central business district is relatively complete. The dense underground passages, viaducts, subway and bus stations, taxi stations, parking lots, traffic information, etc. are conducive to the rapid evacuation of a large number of people and vehicles, and improve the accessibility of the city's overall commuting. sex and commuting efficiency. The establishment and development of the central business district has greatly promoted the construction of the entire city's traffic road network, and the supply of various traffic services has also played a demonstration role in the traffic network of other regions within the region.
Fourth, the location of enterprises and residents. The development and changes in the number of central business districts will also affect the location selection of enterprises and residents. With the needs of regional economic development, the scale and number of central business districts in the region will gradually increase, especially the tightness and tension of land use indicators in urban central areas. With the agglomeration of population, rising business costs, and accelerated construction of new suburban cities, some functions of the original central business district will be assumed by secondary cities, and some enterprises will move from central business districts to secondary central business districts. With the change, the spatial structure of the region gradually changed from single center to multi-center. The original place of residence of the residents may become a new central business district, and as the cost of living rises, the residents may re-select a new place of residence, and the commuting distance changes again.
4. The impact mechanism of the central business district on the regional spatial structure
From a macro perspective, in addition to geographical features such as mountains, rivers, lakes and seas, single-center and multi-center are one of the important manifestations of regional spatial form. The differences in the concentration and dispersion of economic activities among different regions within a region and the differences in their development status in the region will lead to the formation of center and sub-center structures among regions. Traditional urban economics and spatial economics theories believe that the formation of regional monocentric and polycentric structures stems from iceberg costs and increasing returns to scale. When labor is mobile, driven by local market effects and price index effects, industrial products are Certain regions are cheaper to produce, so these regions form the heartland of the region. When multiple mutant units appear within the region (such as the emergence of multiple CBDs), the market potential presents a trend of dispersion in space, thus forming a multi-center structure. The single-center regional spatial organization has a high degree of agglomeration, and the one-way flow of elements to the central city is likely to cause negative problems such as big city disease, high land prices and rents, while the multi-center regional spatial structure is conducive to the balanced development of regional space. Conducive to the cross-regional flow of elements. The central business district can be regarded as a core area within the region. With the continuous development of the regional economy, the growth poles within the region will gradually increase. For example, if the secondary growth poles appear, some elements of the original central business district will spread to secondary area. An increase in the number of central business districts within a region will be conducive to the formation of a polycentric urban structure in the region, while a smaller number and larger scale of central business districts will be more conducive to the formation of a monocentric urban structure. The relative relationship between the development of the central business district and adjacent areas will also affect the regional spatial structure and organizational form. If the output scale and the number of enterprises gathered in the central business district are huge, far exceeding the economic scale and the number of enterprises in other regions in the region, the central business district will become the central city within the region, and the flow of factors between the central business district and neighboring regions will be formed. Gradient, elements mainly flow into the central business district from other regions, that is, the development of the central business district at this time is conducive to promoting the formation of a single-center city structure in the region; if the output scale and the number of enterprises in the central business district are not enough If the flow of factors between the central business district and adjacent areas is in a relatively balanced state, then the central business district and other regions form a polycentric urban spatial structure.
With the development of the central business district, there will be a secondary center (Subcenter). The subcenter is an area between the central business district and the fringe area. The subcenter has a higher population and economic activity carrying capacity than the fringe area, and is more The central business district has the advantages of lower land prices and rents. After the central business district enters a mature stage, the secondary center can undertake some of the urban functions of the central business district, such as bearing the population pressure of the central business district. The number of secondary centers continues to increase with the increase in the population and internal costs of the central business district. The secondary centers and the central business district form a multi-center urban structure, and the regional spatial structure of the multi-center is also changed from the original single center. The spatial structure of a city (one central business district) evolving into multiple central cities (or multiple central business districts). The multi-polarization of urban space is conducive to alleviating various urban diseases, inducing industries and population to move to marginal areas, and finally forming a relatively balanced and stable regional spatial structure to obtain the optimal efficiency of factor spatial allocation. With the development of economic globalization and regional economic integration, the multi-center regional spatial organization form is conducive to the formation of stable network connections among various regions within the region and the efficient flow of factors. The central business district is not only the internal factor that induces the formation of multi-center cities, but also an inevitable trend for the regional spatial structure to move toward multi-center balanced development. From a realistic point of view, the world's famous cities such as Tokyo, New York, and London are all developing in multi-polarity. trend.
5. The impact mechanism of the central business district on the regional network space structure
Since mankind entered the 21st century, with the development of economic globalization and international trade, the economic and social ties between countries and regions have become closer and closer, there are more and more inter-regional cooperation channels, and the cooperation and connections between trans-regional enterprises have become more and more extensive. , the trend of inter-regional networking is becoming more and more obvious. The so-called regional network structure refers to a stable spatial structural relationship formed by various economic and social connections between regions. This spatial structural relationship can be described by network density, network centrality, and individual point centrality. Different regions have different functions and influences in the regional network structure. Central cities become hubs and factor resource allocation centers in the network structure, controlling the flow of factor resources through various contact channels. Other areas become the dominant elements and resources in the spatial network structure, accepting the radiation of the central city. The regional network closely connects related regions through various related channels. Due to differences in regional development, regional functions undertaken by regions, regional openness, and regional industrial advantages and disadvantages, the differences between different regions in the regional network system There are also differences in status and influence, which are reflected in the differences in the overall regional innovation network relationship density and regional network center potential, as well as the influence of a single region on the overall network structure control. In the future, competition between countries and regions will be more manifested in the formulation of high-end element resource channels and regulatory standards. The regional and urban network system provides a broad path for central cities to control various elements and regulatory standards. Obviously, the regional and urban network structure is also an important manifestation of the regional spatial structure. As the center of the region, the central business district is often the hub and node in the regional and urban network structure. The central business district can gather and spread various elements through the regional network channel. Therefore, the stronger the ability of the central business district to gather elements, the more powerful it will be. It is conducive to the stability of the entire region and the stability of the urban network structure. At the same time, the economic and social connections between the central business district and other regions are an important manifestation of the regional network relationship. Therefore, the development of the central business district is conducive to improving the relationship density of the entire regional and urban network. Differences in development between CBDs and other regions can reflect and contribute to uneven regional and urban network structures. From the perspective of a single region and city, the closer the relationship with the central business district, the closer the region and city are to the central hub of the regional network, the more favorable it is to obtain various spillover effects and various elements, thereby controlling other regions The stronger the control and influence of this network, the stronger the influence and radiation ability of the region in the regional spatial structure.
From the perspective of the formation process of the central business district and the regional network structure, the establishment and development of the central business district is the core point of establishing a regional network. After the central business district gathers a large number of service industries, various elements gather in the form of "flow". The central business district and form a network of inter-regional associations. The number of enterprises and the scale of output in the central business district determine the strength and density of the regional network relationship to a certain extent. A large number of corporate headquarters are located in the central business district. The headquarters economy is an important force that exerts factor control in the regional network structure. The central business district is an important driving force for the formation of the regional network structure. At the same time, other regions in the regional network structure will also have an important impact on the development of the central business district. For example, the rapid development of other regions will change the development pattern of the entire region. When there are central cities or multiple central business districts, the influence and control of the original central business districts on the entire regional network gradually decline, and thus the structure of the entire regional network changes.
The influence of the central business district on the three different levels of the regional spatial structure does not exist independently. The influence of the central business district on the location selection of enterprises and residents will eventually be manifested in the form of regional spatial organization, regional network structure, industrial structure and industrial distribution, and industrial specialization. The changes in the division of labor and the structure of the transportation network, and the influence of the central business district on the location selection of enterprises and residents are the micro-basis of the macro-level mechanism and the meso-level mechanism. From the perspective of China’s reality, central business districts are developing rapidly, and central business districts with higher energy levels mostly appear in developed cities in the eastern coastal areas, such as Beijing, Shanghai, Guangzhou and Shenzhen. These developed cities are also populated by Chinese people. The area with the highest density and economic density. On the one hand, the density of central business districts and regional economic activities in China maintains the consistency in space; on the other hand, the internal spatial structure of cities with central business districts is relatively reasonable. From the perspective of urban agglomerations, single centers and Multi-center cities coexist, the urban network structure is gradually formed, the proportion of the service industry in the industrial structure is relatively high, the regional industrial specialization division of labor has been initially formed, the transportation network of these cities is relatively developed, and the balanced path of economic activity space has basically been established. form. Obviously, from a practical point of view, there is a certain correlation between the development of China's central business district and the regional spatial structure. Theoretical mechanism analysis shows that the development of the central business district is closely related to the regional spatial structure, but to what extent the development of the central business district affects the changes in the regional spatial structure, and whether the relevant impact path exists, we need to start from the actual data. It is verified through rigorous empirical methods and means.
