地方政府环境规制竞争背景下地区间的企业污染排放行为

针对地方政府环境规制竞争背景下中国污染排放空间异质性溢出问题，构建中国污染排放空间异质性溢出推拉模型，理论探讨中国区域污染排放在地方政府环境规制竞争背景下空间异质性溢出的形成机理:当由市场效应决定的拉力大于由学习效应决定的推力时，中国污染排放在空间上呈现负溢出效应；当由学习效应决定的推力大于由市场效应决定的拉力时，中国污染排放在空间上呈现正溢出效应。使用中国285个地级市2003-2015年数据，构建异质性空间自回归模型，使用准极大似然估计方法实证检验中国污染排放的空间异质性溢出特征。研究结果显示:（1）中国区域污染排放确实存在空间溢出效应，并且这种溢出效应呈现异质性特征。这种异质性是由不同区域内部不同的拉力与推力较量结果导致；（2）中国工业烟（粉）尘排放强度在空间上主要呈现出正的溢出效应，即中国大部分区域工业烟（粉）尘排放强度受学习效应影响。

Study on Pollution Emission Behavior of Regional Enterprises under the Local Government Environmental Regulation Competition

This paper analyze the pollution emission heterogeneous spatial spillover in the context of environmental regulation competition,construct the push and pull model of Chinese regional pollutant spatial heterogeneity emission,discuss the formation mechanism of spatial heterogeneity in China''s regional pollutant emission under environmental regulation competition:when the pull force which is decided by the market effect is greater than the push force which is decided by the learning effect,China regional pollutant emissions showed negative spillover effects in space; when the push force is greater than the pull force,Chinese regional pollutant emission positive spillover effects in space. Then,using China 285 cities between 2003-2015data,constructing heterogeneous spatial autoregressive model,using quasi maximum likelihood estimation method to empirical test China regional pollutant emission'' spatial heterogeneity process.The results show that:(1)there is spatial spillover effect of China''s regional pollutant emissions,and the spillover effects are heterogeneous. This heterogeneity is caused by the tension and thrust of different regions;(2) China''s discharge intensity of industrial smoke(powder)dust show a positive spillover effect in space,that is,the emission of pollutants from enterprises in most areas of China is mainly affected by the learning effect.
