环境规制对全要素能源生产率的影响是否存在产业异质性?

An Empirical Study of Environmental Regulation's Different Impact on Industrial Total Factor Energy Productivity

本文在按照能源排放强度将33个工业部门分为高、中、低度能耗产业的基础上,测算1999～2007年三大产业环境规制强度和全要素能源生产率,利用面板数据模型对三类行业环境规制与产业全要素能源生产率的关系进行检验。研究结果表明:当前环境规制强度阻碍了中度能耗产业全要素能源生产率的提高和技术创新;高度能耗产业环境规制强度对全要素能源生产率的影响不显著;低度能耗产业环境规制强度适应行业的发展需要,促进技术的进步。环境规制政策的制定应根据不同能耗行业特点区别对待。

Based on the energy consumption intensity, this paper divides the 33 industrial sectors into high, medium and mild energy-intensive industries. We calculate the environmental regulation intensity and total factor energy productivity of three industrial sectors from 1999 ～ 2007 and identify the relationship between environmental regulation and energy industry to- tal factor productivity with the panel data model. The result shows that： the current strength of environmental regulation hin- ders the improvement of moderate energy-intensive industries in total factor energy productivity, technological innovation and efficiency improvements; highly energy-intensive industries＇ environmental regulatory intensity does not significantly influence the total factor energy productivity ; for the mild energy-intensive industries, the intensity of environmental regulation promotes technological innovation. Therefore, the government regulation polices should take into account of different energy consumption intensity of industry.
