    摘要:

    聚焦于长江流域水电能源效率评价及提升问题,综合社会、经济、环境因素,构建投入产出指标体系,选取2008—2017年长江经济带沿线省市的水电相关面板数据,采用DEA法对各地区的水电能源效率进行评价研究。结果显示:长江经济带水电能源效率整体水平较高,其中江苏省和湖北省为“标杆”地区;中上游城市群各指标水电能源效率得分总体较高;不同省市水电能源效率的提升方向不同,如江苏省和浙江省应降低人力投入成本,安徽省和江西省需提高水电装机设备利用小时数;重庆市和贵州省需优先、优质发展地区经济并提高固定资产投资回报率等。最后提出长江经济带各地区应开发优质水电、以水资源为刚性约束,建立绿色水电认证机制,完善投资补助制度,优化供需平衡调节,培养高水平水电人才等建议。

    Abstract:

    In the background of the protection of Yangtze River, realizing high-efficient development of green ecology should be taken as part of the high-quality development of the Yangtze River Economic Belt. Therefore, focusing on the evaluation and improvement of hydropower energy efficiency in Yangtze River and comprehensively considering social, economic and environmental factors, an input-output index system is established. Based on the hydropower-related panel data of the various provinces along Yangtze River Economic Belt from 2008 to 2017, the DEA method is used to evaluate the hydropower energy efficiency of each region. The results show that the hydropower energy efficiency of Yangtze River Economic Belt is at high level as a whole, and Jiangsu Province and Hubei Province are the “benchmarking” regions. The index efficient score of the urban agglomeration in the middle and upper reaches of Yangtze River is generally high. Different provinces have different energy efficiency improvement directions, that is, Jiangsu Province and Zhejiang Province should reduce the investment in human capital, while Anhui Province and Jiangxi Province should increase the equipment utilization hours of the installed hydropower, and Chongqing Municipality and Guizhou Province firstly should develop local economy with high quality and improve the rate of return of the fixed asset investment. Some suggestions are put forward: development of hydropower with high quality, rigid constraint of water resources, establishment of green hydropower certification system, improvement of investment subsidy system, optimization of the balance between supply and demand, and training of high-level talents.
