ABSTRACT: Internet financial risk is not only directly related to the operation and development of the Internet financial system itself, but also has a very important impact on the country’s macroeconomic operation because of its rapid development speed and growing scale of development. As of February 2017, there were 2335 network loan platforms, among which 55 platforms for problem existed. The event, similar to the platform responsible person absconded with money frequently occurred due to lax supervision, credit risk and so on. Therefore, it is very important to evaluate the financial risks of Internet scientifically. This paper takes the top 100 P2P network loan platform risk controls, obtained the net loan home’s rating authentication, as the main research object. The evaluation index system is structured from three dimensions, respectively as follows: liquidity risk, market risk and credit risk. The R-type cluster analysis is used to reduce the dimension of the index system, and the core index evaluation system is obtained finally. On the basis of this, the risk control capability efficiency of that was evaluated for the first time by the classical DEA-CCR model, and then carried out the excellent, the good, the medium and the poor risk control capacity efficiency rating according to the pre-set step size. The excellent refers to the network loan platforms whose ranking is in the first quarter of the comprehensive efficiency derived by DEA-CCR; non-excellent network loan platform refers to the study of 100 network lending platforms in addition to the excellent lending platform other than the research platform. Taking the Excellent P2P network loan platforms as the reference set and the Non-excellent as the evaluation set, this paper also uses the new generalized DEA model to carry on the research of the “catch-up efficiency” and projection analysis, and obtains the projection value of the non-excellent network lending platform, that is, the improvement value of the non-excellent network lending platform in each research index, and provides a feasible way for the non-excellent P2P network loan platforms to change to the excellent P2P network loan platforms.
