Analysis and discussion on the profit model of e-commerce Abstract: The rapid development of e-commerce and its great influence on social and economic life have aroused widespread concern. The continuous development of the Internet has promoted the rise of e-commerce, thus effectively changing the traditional economic growth model. No matter from abroad or at home, the development of e-commerce in China needs to promote a good profit model. This paper discusses that the traditional business model has hindered the rapid development of economy, and two representative business profit models have emerged: online auction model and mobile e-commerce model, and emphatically analyzes the present situation, problems and development trends of these two models. Outline 1, BtoB (business-to-business) e-commerce is mainly aimed at the wholesale of products between enterprises, so it is also called wholesale e-commerce. In fact, e-commerce refers not only to the online retail industry, but also to the enterprise-level e-commerce with an order of magnitude greater market potential than the retail industry. BtoB e-commerce mode is an electronic operation mode that integrates information exchange and transaction between buyers, sellers and middlemen (such as financial institutions) who serve them. The application of this technology will fundamentally change the planning, production, sales and operation mode of enterprises, and even change the basic production mode of the whole industrial society. Therefore, this business model of e-commerce among enterprises has been paid more and more attention, and it is considered by many people in the industry as an important direction of e-commerce development in the future. 2.B to C (business-to-individual consumer) 8848 is the website that adopts this business model. It makes full use of the advantages of federal software companies in the original logistics, the national unified sales chain stores and the brand advantages formed since Changsi, making retail very popular on the Internet. 3.C to C (consumer to consumer) This is the business model adopted by Yi Bei in the United States. At present, several large websites in China, such as Yi Bei and Yabao, also belong to this model. Combined with the current situation that domestic e-commerce has not solved the payment and freight, this way allows users to solve the problems of payment, transportation and inspection by themselves. 4.C to B (individual consumer to business) This is a relatively new concept in the current professional e-commerce website, which is the so-called "reverse auction". It just changed from "cool!" Must! " The website puts forward. Zixunren Company has attracted a lot of attention with this brand-new concept.
