行业特征、环境管制与生产率增长——基于“波特假说”的检验

Industry Characteristics,Environmental Regulation and Productivity Growth——Based on the Test of the “Porter Hypothesis”

运用全局ML指数测算了同时考虑能源和环境约束的中国工业行业绿色全要素生产率,并运用统计学中的聚类分析方法将测算结果聚为三类:高质量产业、中间质量产业和低质量产业。结论表明,高质量产业的环境规制强度维持在一个较高的水平上,而中间质量产业和低质量产业环境规制强度较为薄弱;我国工业的环境规制显著地改善了企业的生产效率,研究结论支持"波特假说"。政府可以通过适当的环境规制政策工具,达到环境保护和经济增长的双赢。

This paper estimates Green Total Factor Productivity of Industries taking into account energy and environmental constraints, The estimation results clustered into three categories： High-quality industrial, intermediate quality industrial and low-quality industry.; Conclusions show that the high-quality industrial environmental regulation intensity is maintained at a higher level, but Intermediate quality industrial and low-quality industrial environmental regulation strength is weak; Environmental regulation of our industry significantly improve the eompany＇s productivity. Research findings support the ＂Porter Hypothesis. ＂ Government may through appropriate environmental regulations policy instruments, achieve a win-win environmental protection and economic growth.
