针对电子商务中零售商的网络空间安全投资问题,本文在考虑存在负外部性的前提下采用博弈论理论首先对两个零售商的投资博弈进行均衡分析,然后对多个零售商的博弈进行均衡分析,并进行仿真模拟,结果表明投资阈值与零售商的网络空间安全水平呈正相关关系,与已投资网络空间安全的零售商数量呈负相关关系。根据结论分析文章提出了需要制定合理的规章制度和采取必要的补贴措施加强对电子商务零售商网络空间安全风险的防范。

In order to solve the problem of cyberspace security investment of retailers in e-commerce, first we analyze two retailers" investment and then analyze multiple retailers" investment based on the negative externality by using game theory. And through simulation, we find that the investment threshold is positively related to the cyberspace security level of the retailers and has a negative correlation with the number of retailers who have invested in cyberspace security. In consequence, we proposed that a reasonable rules or some subsidies should implement to strengthen the e-commerce cyberspace security.
