摘要
随着人们对网上购物的接受程度逐步提高,C2C电子商务越来越火爆。然而由于网络的虚拟性和开放性以及买卖双方的不对称使得诚信成为制约电子商务发展的瓶颈,大部分电子商务平台都采取信用评价体系来解决这一问题,但是效果却不尽如人意。旨在调查现有信用评价体系下的市场整体卖家信分布和结构,发现卖家在各信用等级上的分布曲线呈现出凸向原点的特征,而且随着时间的演进这种趋势愈加明显。通过理论分析我们认为形成倒金字塔形总体信用度分布的根源在于基于交易量的累积信用积分的评级制度、电子商务市场规模的加速增长、市场选择下信用等级和交易量之间的正反馈效应。随着市场规模的扩大,它已不能客观反映卖家诚信,并具有鼓励卖家采取信用炒作等非诚信行为的特点。最后提出了评价体系的改进建议。
As people's acceptance of online shopping gradually improves,C2C e-commerce is more and more popular.However,because of the virtual and open network and the information asymmetry between buyers and sellers,credit has become the bottleneck in E-commerce.Most E-commerce sites use credit evaluation system to solve this problem,but the effect is not ideal.This article aims to investigate the credit distribution of whole market sellers under the present credit evaluation system.We find that the distribution curve of sellers in the credit grade is convex to the origin,and this trend becomes more apparent as time goes.We also find that the cumulative credit rating system based on sale volume,the increase of market scale,the positive feedback effect of sale volume and the credit grade are the mainly causes of this phenomenon.With the expansion of market scale,this evaluation system can no longer fully and accurately reflect the sellers' credit.It also has the effect of encouraging the sellers' dishonest behavior.At last,we provide some advice to improve the credit evaluation system.
