1.1 Subject background and significance
The Internet has many inherent advantages that traditional industries lack. The dissemination of information is no longer subject to geographical restrictions, and has the characteristics of efficient dissemination. The market for idle resources has always existed, but due to the lack of trading channels, many valuable commodities are often discarded or idled, which not only causes waste of resources, but also has a certain impact on the environment. If the Internet is connected with the idle market, the demand for idle commodity transactions can be effectively stimulated through the communication of the Internet, so that idle commodities can be fully utilized.
The occurrence of college students' consumption behavior is essentially material or spiritual needs. As a young group, compared with other groups, college students have stronger demands and are able to accept new things, which ensures the consumption level of college students. However, as a young group, the behavior of consumers is affected by many psychological factors, and they often cannot truly and objectively meet their own needs, and are prone to impulsive consumption, which leads to the purchase of goods that do not meet their actual needs or are not too good. Opportunity for multiple needs. As a group of young people, college students have not yet entered the society. Most of the students’ income comes from family supply, which cannot meet their strong consumption needs to a large extent. Idle items have high cost performance, and to a certain extent, they can match the needs of college students. features. In addition, some studies have shown that young people prefer the Internet and online shopping because they can reduce time cost and interpersonal relationship cost.
1.2 Research status at home and abroad
Domestic offline idle commodity trading markets are mainly concentrated near schools, usually in the form of temporary flea markets or bazaars. Students can get infrequently used or completely idle items in their hands, and entrust others or themselves to trade here. However, such transactions are usually decentralized and uncertain in time and space. This often leads to the problem that most of the students cannot meet the demands of the offline market. Usually, those who have idle goods have no chance to sell them, and those who need to buy them have no way to buy them. This situation often fails to meet the needs of the consumer group.
Compared with the downturn offline, the development of China's online idle goods platform is in full swing. Since the leisure fish shopping platform was launched in June 2014, relying on the large Internet company Alibaba, it has gained a lot of traffic and attention in the development process, gradually driving the huge demand in the domestic idle market. . By 2018, the transaction volume of the platform has exceeded 100 billion, which shows that there is a considerable demand for idle commodity transactions in China. Followed by the support of Tencent and 58 Zhuanzhuan also set foot in the market, and also gained a lot of attention and benefits. In addition, compared with integrated platforms such as Xianyu and Zhuanzhuan, there are many other platforms that focus on vertical segmentation. Aihuishou is one of the outstanding representatives. The platform uses the c2b2cm business model to focus on the electronic digital field. In other words, there is no direct transaction between users, and the transaction can only be generated through the transfer platform. The platform is responsible for purchasing and providing third-party testing, which can reflect the true attributes of second-hand goods to a certain extent. This method effectively solves the pain point that both parties cannot trust, and is sought after and sought after by consumers in the electronic and digital fields.
At present, the vast majority of platforms in the domestic market are social-oriented second-hand property transaction systems. These platforms use the Internet as the information dissemination medium and the logistics system as the physical transportation channel, which can well meet the needs of the society for the transaction of second-hand property resources. However, the situation of domestic campuses has its particularity, but there are few old transaction systems built on campuses, mainly including platforms such as Taoertao, Yuzu Campus, and Xiaoyi. The reason for this is not that there is no market on campus. On the contrary, due to factors such as dense student groups, strong shopping needs, good acceptance of new things, and short-term residence, there is a huge second-hand commodity market on campus. This is also evidenced by the student-organized campus flea market each graduation season. The functions of this kind of application platform are similar. Taking Grapefruit Garden as an example, its main function is an information publishing platform. Students who need to purchase can obtain the seller's contact information on this platform. However, due to functional factors, there are a lot of outdated and invalid information in the system, which brings bad experience to students when purchasing. On the other hand, due to the limitations of objective factors, this kind of platform mainly relies on the independent operation of students, resulting in insufficient user base and unsatisfactory transaction volume. Generally speaking, the market for used resources on campus is quite large, but due to the lack of mature market operation models and experience, many needs cannot be met.
WeChat is an instant messaging application released by Tencent in 2011 for smart terminals. The use and download of WeChat software is completely free, and only a small amount of network traffic fee is required. At the same time, its use is not restricted by mobile terminal systems and operators, and it has become the mobile instant messaging software with the largest user group in Asia. With the continuous development of Internet technology, WeChat is also constantly expanding its own functions to better meet people's needs for software functions. For example, the wallet payment function that we are familiar with and commonly used now, and the WeChat public account platform used to push articles, as well as some subscription accounts, enterprise accounts and other functions. At present, WeChat has been applied to various fields in our daily life, such as radio stations, travel services and so on. In the field of education, research on how to apply WeChat to education is also deepening. Some scholars rely on WeChat to build some learning and exchange platforms, hoping to play a certain role in boosting subject teaching. Some school teachers also create a WeChat public account for subject learning, initially construct a new micro-learning model based on WeChat, and explore the micro-learning model. Application in optimizing teaching classroom. Some scholars also proposed to use WeChat to build applications in life to provide convenience in life.
The WeChat Mini Program is the latest function launched in 2017 based on WeChat. "Father of WeChat" Zhang Xiaolong once said such a sentence: "A small program is an application that can be used without downloading and installing. "Expectation, users can easily and quickly open the corresponding application with the function they need by simply scanning or searching, which also fully reflects the "use and go" in line with today's rapid development With this concept and trend, users who use Mini Programs no longer need to worry about whether their mobile phones have too many applications installed as before. On January 9, 2017, WeChat Mini Programs were officially opened. The biggest advantage of online applications that can be downloaded and used immediately is that it saves space on the mobile phone. The small program can be placed on the top of WeChat or form a shortcut on the desktop of the mobile phone, so that users can uninstall the cumbersome applications in the mobile phone and use Applets instead. Users don’t need to worry about installing too many apps, and they don’t have to uninstall some apps to save space. Applets can be obtained by searching or scanning QR codes. Chat interface sharing.
The development of WeChat applets is relatively simple. When developing WeChat applets, developers can directly call the API function interface that comes with WeChat to realize the required functions. It is also very simple for users to use the Mini Program. Users only need to open their frequently used WeChat software, search or scan directly in WeChat to enter the Mini Program for use. The emergence of small programs has greatly shortened the development cycle of developers. Once a small program is released, it is quickly recognized by everyone and actively used in various fields. Some scholars have used WeChat mini-programs to build a platform for unemployed students on campus and to make appointments for domestic services. Research on the application of WeChat Mini Programs in the field of life is also deepening.
