Abstract: Based on the 216 wind power industry policies issued by country's departments at the ministerial level and above from China's economic transition period till now (from year 1994 to 2015). This paper employed the Negative Binomial Regression Estimate Model to research the impact of the potency dimension of industrial policy and regional innovation environment on the innovation performance of wind power enterprises. The research results show as follows: the potency dimension of finance and taxation support policy and the technical support policy have a positive effect on innovation performance of wind power enterprises; the potency dimension of technical specification policy has a negative effect on innovation performance of wind power enterprises. The effect of wind power industry policy on the innovation performance of micro-enterprises is affected by the regional innovation environment and there are significant differences. The effect of wind power industry policy on different ownership enterprises' innovation output efficiency also has significant differences. This paper suggests that industrial policies should be based on the regional innovation environment and the enterprise type difference, to implement differentiated innovation-driven industrial policies, so as to make industrial policy better serve the improvement in the innovation performance of wind power enterprises.
