[Abstract]:E-commerce has come into being with the rapid development of Internet and information technology, and has experienced the process of sprout, exploration and gradual expansion, which has developed rapidly all over the world. With the concept of "Internet" put forward, the economic development of "e-commerce" has become increasingly obvious, e-commerce has penetrated into all aspects of different industries. C2C model as one of the most important model of e-commerce, The traditional face to face consumption mode of transaction entity has been changed, but because of the characteristics of asymmetric information among different entities, there are certain risks in the transaction. Mutual trust between trading entities is the prerequisite for both parties to reach a transaction. However, with the development of C2C electronic commerce, a large number of "fraudulent" trading entities have emerged, and the credit problem has become the bottleneck of its sustainable development. How to construct C-2 C e-commerce credit evaluation system is concerned by business circles and scholars. In order to reduce the transaction risk between entities, improve the transaction efficiency of both parties, and promote the healthy development of C2C e-commerce, this paper sets up a credit evaluation model to evaluate the credit of buyers and sellers in all directions and accurately from the perspective of creating an honest trading environment. The main work includes the following three parts: the first part, introduces the C2C e-commerce reputation related theory and the trading subject reputation formation mechanism, summarizes and analyzes the existing trading subject reputation evaluation mechanism and model. This paper focuses on the credit evaluation mechanism of the improved way and the principles of the establishment of the model. The second part, according to the C2C e-commerce website transaction flow, from the initial registration, transaction goods and returned goods to the buyer and seller credit evaluation study, respectively, build evaluation buy, seller initial reputation, The weighted model of transaction reputation, return credit and comprehensive reputation. Deeply analyze the dynamic utility of transaction value utility factor, feedback evaluation accuracy utility factor, time utility factor and return rate utility factor in evaluating buyer's reputation. This paper focuses on the dynamic utility of transaction value utility factor, reliability utility factor, time utility factor and return rate utility factor when evaluating seller's reputation. The third part simulates the trading environment and verifies the feasibility and effectiveness of the proposed model by numerical examples. The experiment shows that, in this paper, the seller's reputation evaluation model can make up for the deficiency of traditional reputation evaluation model which can not evaluate the initial reputation of the trading body, and the reputation value of the seller in different periods can also be compared. And has better credit differentiation ability; The dynamic value of buyer's reputation can effectively identify the types of fraud taken by non-honest buyers, and the seller's reputation evaluation model has strong ability in preventing "reputation fraud", "credit collusion" and "reputation denigration".
