Study on the effect of wind power industry policy types on the innovation performance of different ownership enterprises: Evidence from China

Abstract

Studying effect of different types of wind power industry policies on the technological innovation of enterprises is the core issue that academics and policymakers pay close attention to nowadays. Based on systematically carding the quantization of 254 wind power industry policies issued by governmental departments at the ministerial level and above in China from 1994 to 2016, this paper categorizes innovation policy instruments into supply-side, environmental-side, demand-side, and employs Negative Binomial Regression Estimation Model to research the impact of industry policies on wind power enterprises’ innovation performances. The research results show as follows: the effect of different types of policy instruments on enterprise innovation is significantly different: demand-side policy and environmental-side policy have significant inhibitory effects on enterprises’ innovation performance, but supply-side policy has a significantly positive effect especially on the core technological innovation. The effect of wind power industry policies on the innovation quality of different ownership enterprises is significantly different: comprehensive policy and supply-side policy have positive impacts on the core technological innovation of private-owned enterprises, while demand-side policy and environmental-side policy have only positive impacts on the non-core technological innovation of state-owned enterprises. Finally, this paper proposes certain recommendations to consummate wind power industry policies for China.
