长江经济带城市绿色发展质量测度及其影响因素分析

The measurement of urban green development guality in the Yangtze river economic belt and the analysis of its influencing factors

基于长江经济带2003—2017年11个省会城市面板数据,运用熵值法对绿色发展质量进行动静结合分析,采用Tobit面板回归模型对影响绿色发展质量的因素进行实证分析。结果表明,长江经济带城市绿色发展质量呈波动上升趋势,地区差异明显,总体呈从上游城市向下游城市再向中游城市逐步递减的趋势,即“两端高、中间低”的趋势;经济发展水平、市场开放、外商投资水平、环境规制对绿色发展质量提高作用显著,而产业结构、科技进步、城镇化则对绿色发展质量起到抑制作用。从对接国家战略、增加政府扶持、优化产业结构、统筹区域差异4个方面提出了长江经济带城市绿色发展质量提升的优化路径。

Based on the panel data of 11 provincial capitals in the Yangtze river economic belt from 2003 to 2017,the entropy method was used to analyze the quality of green development,and Tobit panel regression model was used to analyze the factors affecting the quality of green development.The results show that the quality of green development of cities in the Yangtze river economic belt is fluc⁃tuating and rising,and the regional differences are obvious.The overall trend is gradually decreasing from the upstream cities to the downstream cities and then to the middle cities,that is,the trend of“high at both ends and low in the middle”;The level of economic development,market opening,foreign investment and environmental regulation play a significant role in improving the quality of green development.However,industrial structure,scientific and technological progress and urbanization play an inhibitory role in the quality of green development.The optimization path of improving the quality of urban green development in the Yangtze river economic belt was put forward from four aspects:Docking national strategy,increasing government support,optimizing industrial structure and coor⁃dinating regional differences.
