摘 要
作為一種新興的電子商務模式，C2C電子商務近年來表現(xiàn)出巨大的商業(yè)前景，然而C2C電子商務卻面臨著缺乏消費者信任的發(fā)展障礙。由于交易雙方信息不對稱程度的加大和網(wǎng)絡欺詐行為的不斷發(fā)生，使得消費者對C2C網(wǎng)上交易所感知的風險大大增加，不信任感增大。對于C2C電子商務，由于交易主體是個人，信任問題顯得更加突出。信任問題是使消費者不愿在線購物的主要原因之一。因此，本文著重對C2C電子商務中的信任問題進行研究。
本文首先對信任理論和在線信譽系統(tǒng)進行了系統(tǒng)的介紹；其次，針對在線信譽系統(tǒng)的核心——信任模型，本文對模型進行有效性分析，分析結(jié)果表明，現(xiàn)行的信任模型沒有考慮交易價值、評分用戶的信用度和近期信用度等關鍵因素，不能有效地制止“信用詆毀”和“信用榨取”現(xiàn)象，不利于激勵用戶誠信交易，使得某些不誠信的機會主義者有可乘之機。針對目前信任模型存在的缺陷，本文建立了C2C個性化信用計算模型，并根據(jù)用戶的類型進行了有效性檢驗。
本文旨在將信任的主要影響因素引入到信任模型中，提出一種信任體系的構建方式，為C2C電子商務的信任提供一些改進的策略。

 Abstract
As a new E-commerce model, C2C E-commerce demonstrates great business potential in recent years. However the absence of consumers’ trust is a main barrier which the C2C electronic commerce meets. The risk of consumers’ feeling on shopping in C2C transaction platform is bigger than that in the traditional business pattern due to the much more asymmetric information and frequent occurrence of web cheating behavior. As the both party of C2C E-business participants are individuals, the trust problem is even worse. Trust problem is one of the main reasons why consumers hesitate to go shopping online. Therefore, it is very significant in studying the trust problem of the C2C E-commerce.
Firstly, this paper introduces credit theory and online reputation systems. Secondly, according to the core part of online reputation systems, this paper establishes a model to eva luate its validity. And the results point out that the current trust model have not eva luated some key factors, such as transaction value, user’s credit and recent credit. So, it can not effectively decrease the possibilities of “credit slander” and “credit squeeze”, and it will surely give rise to negative effects on users’ transaction experience. In order to solve the defects mentioned above, this paper establishes a C2C personalized credit computational model, and eva luates the validity in accordance with the type of users in this model.
The purpose of this paper is to introduce the influencing factors of trust into the trust model, find a new way to build a new trust system, and hope to provide some improved strategy to the trust of C2C E-commerce.
