基于3D框架下的中原城市群环境污染排放研究

摘要

Based on the panel data from 2005 to 2015,this paper applied the three-dimension framework pro-posed by the World Bank to analyze the relationship between density,distance,division and industrial wastewater, SO2and soot emission in Central Plains Urban Agglomeration.The research find that:Firstly,there is an inverse U-shaped curve between economic density and environmental pollution.and the inflection point has appeared,which means pollution is being reduced with increasing economic density.Secondly,economic distance reduction has a positive impact on environment quality.Thirdly,the impacts of fragmentation on three pollutants are inconsistent.It increases industrial wastewater,while decreases emissions of SO 2and soot.%在世界银行2009年发展报告提出的密度、距离、分割三大因素框架下,利用2005—2015年中原城市群面板数据,分析密度、距离和分割与中原城市群工业废水、工业SO2和工业烟尘排放强度的关系.结果发现:经济密度因素与环境污染呈倒"U"型曲线关系,且拐点已经出现,经济密度的进一步增加会减弱环境污染物的排放;距离的缩减会改善环境质量;分割因素对3种污染物的影响出现分化,市场分割程度越大,工业废水排放量越大,而工业SO2和烟尘的排放量则存在减少的趋势.
