长江经济带经济增长质量时空演化研究

Research on the Temporal and Spatial Evolution of Economic Growth Quality in the Yangtze River Economic Belt

基于2006-2016年长江经济带108所城市的面板数据,构建DEA模型对长江经济带各城市经济增长质量进行测算。结果表明:(1)长江经济带经济增长质量一直维持在1上下浮动,在2011年达到最大峰值,2013年后经济增长质量一直逐年上升;(2)长江经济带各城市的区域差距仍然存在,经济增长质量从高到低依次是下游、上游、中游,中游与下游间的经济增长质量差距较大;(3)从空间上来看,近10年来各城市的经济增长质量均发生了较大差异,经济增长质量较高的城市逐步向长江上游和下游分散,而长江中游的经济增长质量相对来说处于较低水平。

Based on the panel data of 108 cities in the Yangtze River Economic Belt from 2006 to 2016,the DEA model was constructed to measure the quality of economic growth of each city in the Yangtze River Economic Belt. The results show that:(1)The economic growth quality of the Yangtze River Economic Belt has been maintained at a fluctuation of 1,reaching its maximum in 2011. And it has been increasing year by year since 2013;(2) The regional gap between cities in this zone still exists. The quality of economic growth is from high to low,which is followed by downstream,upstream and midstream. And its growth between middle and downstream is relatively large;(3) From a spatial perspective,the quality of economic growth in each city has changed greatly in the past decade. Cities with higher one are gradually dispersed to the upper and lower reaches of the Yangtze River,however,the middle reaches is at a relatively low level.
