The objective of this paper is to investigate the changes in the regional energy consumption at the provincial level in China from 2007 to 2016 by introducing a spatial shift-share decomposition approach to measure the neighborhood effect on the regional energy efficiency change through the establishment of a spatial weight matrix considering the geographical and economic proximity. Using this decomposition method, the regional advantage (or disadvantage) in energy efficiency can be revealed, excluding the influence of neighborhood performance in terms of energy efficiency. The results indicate that a shift from energy intensive industrial productions toward the less energy intensive service sector occurs in almost all provinces of China over the period observed; there is significant spatial differentiation on the spatial decomposition of the efficiency change component across provinces, and the changes in energy efficiency in provinces of Jing-Jin-Ji, Yangtze River Delta, Chengdu-Chongqing, Guanzhong Plain, Pan-Pearl River Delta city agglomeration and the three provinces in Northeast China are mainly affected by the neighborhood effect. Our empirical findings suggest that energy policy making should be more concerned about the spatial correlation and coupling effects of energy consumption, especially in the national urban agglomeration of China.
