    摘要:

    以全国30个省级行政区为研究对象,采用超效率SBM模型测算2010—2019年绿色水电碳减排效率,分析比较了区域差异;采用泰尔指数计算区域内和区域间差距及其对总体差距的贡献度,并采用Malmquist指数对效率进行分解分析。结果表明:我国绿色水电碳减排效率西部最高,中部次之,东部最低;效率的区域内差距高于区域间差距,且东部各省发展差距对总体差距的贡献最大;除规模效率外,其余效率均上升。建议我国应合理布局水电开发,重视省际互补协作,扩大水电规模。

    Abstract:

    Taking 30 provinces in China as the research object, the super-efficient SBM model is used to calculate the carbon emission reduction efficiency of green hydropower from 2010 to 2019. The hierarchical cluster analysis is used to compare regional differences. And then, the within-group inequality, between-group inequality and their contribution to the overall inequality are calculated by using Theil index. Finally, the Malmquist index is used to decompose and analyze the efficiency. The results show that the development efficiency of green hydropower in China is the highest in the west, followed by the middle and the lowest in the east. The within-group inequality of efficiency is higher than the between-group inequality, and the development inequality of eastern provinces contributes the most to the overall inequality. Except for the scale efficiency, all the other efficiencies have increased. Therefore, it is necessary to rationally arrange hydropower development, attach importance to inter-provincial complementary cooperation and expand hydropower scale.
