中国环保投资对城镇化影响的实证研究——基于中国分区域省份数据的面板回归分析

An Empirical Study on Relationship of China's Environmental Investments and Urbanization:Based on Analysis of Panel Data Regression in China's Sub-Regional Provinces

利用中国30个省份2008~2012年的面板数据,针对环保投资与城镇化之间的影响关系进行实证研究。研究发现：三项环保投资在全国层面和东中西部三大区域层面的影响作用是不同的。其中,城市环境基础设施建设投资对中部地区和西部地区的正向促进作用明显,但是对东部地区无显著影响;工业污染源治理投资对各区域城镇化水平均呈现负的影响作用;建设项目＂三同时＂环保投资对于全国层面、东部地区和中部地区均有显著影响,其中对全国的城镇化水平影响为正,对于东部地区和中部地区的影响均为负。
