环境规制对企业生产率的影响是当前学术界的研究热点,但基于地理区位视角的研究较少。应用中国环境规制地理空间数据和微观企业数据,实证分析了环境规制空间差异与环境规制空间相关性对企业生产率的影响。结果表明,环境规制空间差异与企业生产率之间存在显著的倒U型关系;环境规制空间相关性作用显著,邻近城市环境规制提升有利于本城市企业生产率增长;环境规制对生产效率高的企业具有显著促进作用,但对生产效率低的企业影响不明显;不同的地理区位,环境规制对企业生产率的影响不同,相对于中西部地区,东部地区环境规制促进企业生产率增长的作用更为显著。本文揭示了在地理区位视角下,针对环境规制对企业生产率的影响,“成本假说”和“波特假说”具有各自的解释空间。
The impact of environmental regulation on the productivity of enterprises is currently the hotspot of academic research, but there are few researches based on the geographic location. Applying the data of China’s environmental regulation geospatial data and micro-enterprises, this paper empirically analyzes the impact of the spatial difference of environmental regulation and the spatial correlation of environmental regulation on enterprise productivity. The results show that there is a significant inverted U-shaped relationship between spatial differences of environmental regulation and firm productivity. The spatial correlation of environmental regulation plays a significant role. The improvement of environmental regulation in neighboring cities is conducive to the growth of enterprise productivity in this city. But it has no obvious effect on the enterprises with low production efficiency. The impact of environmental regulation on enterprise productivity is different in different geographical locations. Compared with the central and western regions, the environmental regulation in the eastern region has a more significant effect on promoting enterprise productivity growth. This paper reveals the impact of environmental regulation on firm productivity from the perspective of geographic location. Each of the “cost hypothesis” and “baud hypothesis” has its own interpretation space.
