摘要: 采用Min-DS模型以及Kernel密度估计函数,在推进绿色创新发展条件下,对长江经济带沿线11省市第三产业能源效率进行测度并分析其时空差异。结果表明,长江经济带第三产业能源效率整体波动较大,空间差异呈缩小趋势;下游地区(江苏省、上海市和浙江省)能源效率表现突出,效率值提高且空间差异缩小;中游地区(湖北省、湖南省、安徽省和江西省)空间差异缩小但效率值整体较低,上游地区(云南省、贵州省、重庆市和四川省)效率水平较高,但空间差异扩大。11省市能源效率仍有上升空间,需要注意能源节约,省市间效率变动差异较大,需因地制宜探求效率提升路径。

Abstract: Using the Min-DS model and Kernel density estimation function, the energy efficiency of tertiary industry in 11 provinces and cities along the Yangtze River Economic Belt was measured and its spatio-temporal differences were analyzed under the condition of promoting green innovation development. The results showed that the overall energy efficiency of the tertiary industry in the Yangtze River Economic Belt fluctuated greatly, and the spatial difference showed a decreasing trend; the energy efficiency in the downstream area(Jiangsu Province, Shanghai City and Zhejiang Province) was outstanding, the efficiency value was improved and the spatial difference was reduced; the spatial difference in the midstream area(Hubei Province, Hunan Province, Anhui Province and Jiangxi Province) decreased, but the overall efficiency value was low, and the efficiency level in the upstream area(Yunan Province, Guizhou Province, Chongqing City and Sichuan Province) was high, but the spatial difference expanded. There was still room for improvement in energy efficiency in 11 provinces and cities. Attention should be paid to energy conservation. There were great differences in efficiency changes among provinces and cities, so it was necessary to explore the path of efficiency improvement according to local conditions.

Key words: Yangtze River Economic Belt, tertiary industry, energy efficiency, Min-DS, Kernel, temporal and spatial differences
