产业协同集聚与环境污染治理:助力还是阻力

Industrial Co-agglomeration and Environmental Pollution Control:Impetus or Resistance

基于2003—2016年中国30个省份的面板数据,采用双向固定效应、空间面板杜宾等计量方法,并结合中介效应检验模型,实证检验产业协同集聚对环境污染治理的影响。研究表明:产业协同集聚与环境污染呈稳定的倒U型关系,即短期内产业协同集聚表现为环境污染治理的阻力,但长期看又会逐步转化为环境污染治理的助力,且这种影响效应不存在地区差异;产业协同集聚的空间溢出效应具有地区差异性,其中东部地区的溢出效应不显著,中西部地区的溢出效应则较为显著;科技创新是产业协同集聚影响环境污染治理的一个有效中介变量。因此,应大力推进产业协同集聚战略,因地制宜制定产业协同集聚发展政策,构建联防联控的协同治污举措,推进环境污染的有效治理。

Based on the panel data of 30 provinces in China from 2003 to 2016,the application of the time-space fixed effect,spatial panel Dubin and other measurement models,combined with the mediation effect test model,this study empirically tested the impact of industrial co-agglomeration on environmental pollution control.The results show that there is a stable inverted U relationship between industrial co-agglomeration and environmental pollution,and there is no regional difference,which indicates in the short run,the co-agglomeration of industries represents the resistance of environmental pollution control,and in the long run,it will gradually be transformed into the assistance of environmental pollution control;there are regional differences in the spatial spillover effect of industrial co-agglomeration,of which the effect in the eastern region is not significant,and the spillover effect in the central and western regions is more significant;scientific and technological innovation can be a mediating variable of industrial co-agglomeration affecting environmental pollution.Therefore,it is necessary to vigorously promote the strategy of industrial co-agglomeration,formulate policies for industrial co-agglomeration development in line with local conditions,and establish joint prevention and control measures,so as to promote the effective management of environmental pollution.
