Abstract

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
