民营资本的进入对我国风电产业发展的影响——基于断点回归的分析

Private Capital into its Influence on the Development of the Wind Power Industry in our Country——Based on the Breakpoint Regression Analysis

为克服单差法存在变量内生性,倍差法对于控制组的严格要求往往无法得到满足,故文中采用断点回归的分析方法,在无对照组的情形下,对我国风电产业2012~2015年的资产总计、主营业务收入以及发明专利数月度数据进行实证研究,探究民营资本的进入对我国风电产业的影响。实证结果表明,从短期看,民营资本的进入对我国风电产业规模与技术效率具有统计上的显著正面作用,具有一定的经济意义;另外,这一机制的推行对产业创新产生了显著的负面作用。

In order to overcome the variable endogenous problem of the single difference method, the strict requirement that the multiple difference method to the control group was often unable to be satisfied, so this paper adopted a breakpoint regression analysis method. In the absence of a control group,this paper made anempirical research by using the monthly data of the total assets, the main business income and the number of invention patents in China＇s wind power industry from 2012 to 2015, and explored the impact of private capital entry on China＇s wind power industry. The empirical results show that the entry of private capital had a statistically significant positive effect on the scale and technical efficiency of China＇s wind power industry, and it had certain economic significance in the short term. However, the implementation of this mechanism had a significant negative impact on the wind power industry innovation.
