Abstract:

Energy eco-efficiency is a concept trying to integrate ecological and economic benefits arising from energy utilization and serves as a measurement of the efficiency in energy-environment-economy system. Based on the SBM model considering undesirable output, this paper first measured the energy eco-efficiency of provinces in China from 1997 to 2012. Then it analyzed the spatial distribution and the evolution of energy eco-efficiency from three aspects—scale, intensity, and grain of spatial patterns; and finally, it verified the spatial spillover effects and the influencing factors of energy eco-efficiency in different provinces by means of spatial econometric model. Conclusions can be drawn as follows: (1) the overall energy eco-efficiency is relatively low in China, of which energy-inefficient areas account for about 40%. Provinces of Guangdong, Hainan, and Fujian enjoy the highest energy eco-efficiency, but provinces of Ningxia, Gansu, Qinghai, and Xinjiang are representative areas with low efficiency, thus making a U-shaped evolution pattern of China's overall energy eco-efficiency; and in local regions, there are four evolution patterns: increasing, fluctuating, mutating, and leveling. (2) At the provincial level, China's energy eco-efficiency features significant spatial agglomeration globally and locally. High-High agglomeration mainly occurred in the eastern and southern coastal areas, and Low-Low agglomeration, in the northwest and middle reaches of the Yellow River. The change in spatial patterns mainly occurred in areas with High-Low and Low-High agglomeration, and the most remarkable change took place in the Beijing-Tianjin-Hebei region. (3) There exists a significant spatial effect of energy eco-efficiency among provinces of China. For the energy eco-efficiency of a certain region, the spatial spillovers from adjacent regions outweigh the influence of the error impact from adjacent regions. Industrial structure hasgreat influence on the energy eco-efficiency.
