Analysis of the Effects and Regional Heterogeneity of Wind Energy Industry Policy in China

Abstract

Subject to the dual constraints of energy and climate, wind energy has become a major development trend in the world as a renewable energy next only to hydropower. In this paper, the effects of wind energy industry policy are evaluated based on fixed-effect model, and the regional heterogeneity of wind energy industry policy is discussed based on wind resources. It is concluded that the implementation of wind energy industry policy can significantly increase wind power output without regard to the the regional differences in wind resources. In terms of the effectiveness of policy, demand-oriented policy instruments play a most important role, supply-oriented policy instruments play the second role, and environment-oriented policy instruments play the weakest role. Considering the regional differences in wind resources, the effect of the same policy varies greatly in areas with different wind resources: Supply-oriented policy instruments are slightly more effective in areas with rich wind resources, demand-oriented policy instruments are more effective in areas with poor wind resources, and environment-oriented policy instruments are significantly more effective in areas with poor wind resources.
