摘要
本文首先利用超效率DEA模型,对长江经济带整体及分区域生态效率进行计算与分析,发现整体生态效率偏低,但下游区域的效率值明显高于中上游区域;为了进一步探究其地区差异的演化特征,又对长江经济带进行了分区生态效率收敛检验,结果并未出现明显的收敛态势,但不同区域的表现不同。提醒我们在注重提升生态效率较低区域的整体效率的同时,缩小生态效率较高地区的内部差别。
This paper firstly uses the super-efficiency DEA model to calculate and analyze the overall and sub-regional eco-efficiency of the Yangtze River Economic Belt and finds that the overall eco-efficiency is low, but the efficiency value of the downstream region is significantly higher than that of the midstream and upstream region;In order to further explore the evolutionary characteristics of regional differences, the e-co-efficiency convergence test of the Yangtze River Economic Belt was carried out,showing no obvious conver-gence, but the performance of different regions is different. Remind us to reduce the internal differences in areas with higher eco-efficiency while focusing on improving the overall efficiency of areas with lower ecoefficiency.
