Abstract: From the macroeconomic perspective, this paper establishes a performance evaluation system of venture capital covered by all indicators. Based on questionnaire survey and expert evaluation method, 27 secondary indicators of six influencing factors, namely macroeconomic fluctuation, supply and demand of venture capital, growth of enterprises, technological innovation ability, internal control ability and financial status of enterprises, are selected, and a preliminary risk performance evaluation index system is established. After removing the interference evaluation index, a more comprehensive, scientific and reasonable performance evaluation index system of venture capital is established, and then the weight proportion of each evaluation index's importance degree is determined based on AHP. The results show that the evaluation results of the proposed performance evaluation system of venture capital are more accurate than those of the traditional evaluation system, and tend to the real value of risk of investment activities.
