环境规制、产业升级与城镇化质量——基于省级面板门槛模型的研究

Environmental Regulation,Industrial Upgrading and Urbanization Quality——A Research Based on Provincial Panel Threshold Model

构建了环境规制、产业升级与城镇化质量之间的关系理论框架,利用2005—2014年中国的省级面板数据,使用固定效应模型来检测产业升级、环境规制与城镇化质量之间的作用关系。为进一步说明,分别以环境规制和产业升级作为门槛变量,表明三者之间的作用机制。研究结果显示,产业升级和环境规制对城镇化质量有显著的作用,产业升级和环境规制对城镇化质量的影响存在显著的环境规制强度和产业升级水平的双门槛效应;产业升级能够推动城镇化质量的提升,倘若不能有效促使企业进行产业升级,而仅仅只是依靠强化环境规制来提升城镇化质量,是不可持续的。

The research first built a theoretical framework of relationships among environmental regulation,industrial upgrading and urbanization quality; and based on 30 provinces＇ panel data from 2005—2014 in China,the research tested the interaction relation of environmental regulation,industrial upgrading and urbanization quality by using fixed effect model. For further elaboration,this paper chose environmental regulation and industrial upgrading as threshold variables to indicate the function mechanism among the three.The conclusions are as follows： industrial upgrading and environmental regulation have significant effect on the urbanization quality; environmental regulation intensity and the level of industrial upgrading have a significant double threshold effect on the quality of urbanization. Further analysis indicated that the improvement of urbanization quality is based on industrial upgrading. If the enterprises cannot be effectively promoted to conduct industrial upgrading,but urbanization quality is improved only relying on environmental regulation,it is not sustainable.
