环境规制强度对污染密集行业绿色技术创新的影响研究——基于2003—2010年面板数据的实证检验

Research on the Effect of Environmental Regulation Intensity on Green Technological Innovation of Pollution Intensive Industries——Empirical Test Based on Panel Data of 2003—2010

基于国内外环境规制与技术创新的研究成果,以绿色产品创新和绿色工艺创新作为被解释变量,环境规制强度作为解释变量,行业规模和创新人力资源投入作为控制变量,构建了环境规制强度影响绿色技术创新的面板数据模型,并选取我国16个污染密集行业2003—2010年面板数据进行实证研究.研究结果表明:在考虑行业规模和创新人力资源投入两个控制变量的情况下,政府制订严厉的环境规制政策可有效促进污染密集行业实施绿色技术创新,但未考虑以上两个控制变量时,环境规制强度对污染密集行业的绿色技术创新则产生了负效应.这一实证结果验证了"不完全环境规制"现象的存在,也证实"波特假说"成立的条件性.

Based on the achievements of environmental regulation and technology innovation at home and abroad, the panel data models of the environmental regulation intensity＇s effect on green technological innovation were established. In these models, green product innovation and green process innovation were used as the explained variables, environ- mental regulation intensity was used as explanatory variable, scale of industry together with investment on innovative human resources were used as control variables. Furthermore, the empirical study was conducted with 2003--2010 panel data from 16 pollution intensive industries. The results show that in the consideration of two control variables of industry scale and the investment of innovative human resources, government stringent environmental regulation policy would promote the implementation of green technology innovation in pollution intensive industry. But when the two con- trol variables were not considered, environmental regulation policy would have negative effects on green technology in- novation of pollution intensive industry. The empirical results verify the existence of incomplete environmental regula- tion phenomenon, and also confirm the conditional existence of Potter hypothesis.
