【摘要】：资源环境日益成为影响区域经济发展的重要因素,如何使资源环境与经济发展的协调发展,以最小的生态代价获取最大的经济效益,是中国面临的重要问题。笔者采用超效率DEA的方法,对中国2003年~2012年间30个区域的面板数据进行生态效率的全面评估,从中探究区域生态效率的变动趋势和时空特征,构建Malmquist指数从技术进步水平和技术效率水平考察影响区域生态效率变动的因素。结果表明:生态效率的区域差异并没有呈现东、中、西的区域格局,而是呈现“东西部高,中部低”东、西、中的发展趋势。从影响生态效率的技术进步和规模收益来看,技术进步已成为生态效率变动的主要因素,规模收益呈现递减趋势。最后针对以上研究提出提高中国生态效率,促进区域资源环境与经济协调发展的政策建议。
[Abstract]:Resources and environment have increasingly become an important factor affecting regional economic development. How to make the coordinated development of resources and environment and economic development and obtain the greatest economic benefits at the minimum ecological cost is an important problem facing China. By using the method of super efficient DEA, this paper makes a comprehensive evaluation of the ecological efficiency of the panel data of 30 regions in China from 2003 to 2012, probes into the changing trend and temporal and spatial characteristics of regional ecological efficiency, and constructs the Malmquist index to investigate the factors affecting the change of regional ecological efficiency from the level of technological progress and the level of technical efficiency. The results show that the regional differences of ecological efficiency do not show the regional pattern of east, middle and west, but show the development trend of "high east and west, low middle" east, west and middle. From the point of view of technological progress and scale income which affect ecological efficiency, technological progress has become the main factor of ecological efficiency change, and scale income shows a decreasing trend. Finally, in view of the above research, this paper puts forward some policy suggestions to improve the ecological efficiency and promote the coordinated development of regional resources, environment and economy.
