再生资源产业集聚与区域环境污染——来自我国省域面板数据的实证分析

Renewable Resources Industry Agglomeration and Environmental Pollution:an Empirical Analysis based on Provinces' Panel Data

再生资源产业具有"双重"环境外部性特点,且在我国已经基本形成集聚发展业态,再生资源产业集聚与区域环境污染的关系备受关注。以产业集聚的环境外部性为切入点,利用我国25个省份再生资源产业面板数据,采用广义最小二乘法(GLS)实证分析我国总体以及东、中、西部3个区域再生资源产业集聚与区域环境污染的关系。研究表明:我国再生资源产业集聚与环境污染总体呈现"非标准倒U型"关系,再生资源产业集聚化发展总体上加剧环境污染;我国东、中、西部再生资源产业处于不同产业集聚发展阶段,产生差异性环境污染效应。在此基础上,从差异化配套政策、环境规制、市场环境和回收体系等方面提出对策建议,以期为再生资源产业生态化集聚发展提供有益参考。

Renewable resources industry has the characteristics of dual environmental externality,and has been formed agglomeration development in our country.The relationship between the cluster of the renewable resources industry and regional environmental pollution has attracted more and more attention.Taking environmental externality of the industry agglomeration as the breakthrough point,based on the panel date of renewable resources industry of 25 provinces in our country,using generalized least squares（GLS）empirically analyzes the relationship between the cluster of the renewable resources industry and regional environmental pollution in our country and eastern,central,western regions of our country.Results show that：the relationship between the cluster of the renewable resources industry and regional environmental pollution presents the ＂non-standard inverted U-shape＂ in our country,and agglomeration development of the renewable resources industry overall aggravates environmental pollution;renewable resources industry in eastern,central and western regions of our country are in different stages of agglomeration development,and produce different environmental pollution effect.On this basis,some suggestions which are about the differentiation supporting policies,environmental regulation,market environment and recycling system have been proposed,in order to provide useful references for the development of the ecological agglomeration of renewable resources industry.
