Abstract: Recently, Internet Non-public financing has stimulated the innovation and entrepreneurship in China. In order to systematically investigate internet non-public financing, this paper designs an evaluation index system towards platforms based on their characters, and builds a dynamic comprehensive evaluation model to dynamically evaluate platforms' comprehensive performance. In modeling, CRITIC method and subjective weight model are combined to weight indices statically. Different periods of time are given different weights by time degree and the dynamic evaluation model is built by ideal point method finally. This paper collects 30 Chinese internet non-public financing platforms' data of five seasons-from January, 2016 to March, 2017, covering 642 crowdfunding projects and involving "amount of financing", "number of followers", and other six indicators. After conducting an evaluation study with collected data, this paper ranks the 30 platforms by their comprehensive performance. The result shows that this evaluation model has favorable maneuverability and rationality, which can offer suggestions for regulatory authorities, investors and financers to make relevant decisions.

Key words: dynamic comprehensive method, Internet finance, non-public financing platforms
