To study the spatial distribution and its evolving patterns of ecological civilization construction efficiency in China is of great help to clarify the spatial difference mechanism of ecological civilization construction efficiency, and of an important guiding significance and reference value for narrowing down regional differences and probing into the driving factors. Ecological civilization construction is a complex process, and its core lies in the coordinated development of each component of the compound natural-economic-society (N-E-S) ecosystem. Therefore, based on the compond N-E-S (nature-economy-society) ecosystem theory and the perspectives on the ecological civilization construction efficiency connotation, this paper establishes an input-output indicators system for ecological civilization construction efficiency and applies the undesirable output SBM model to calculate China's ecological civilization construction efficiency between 2003 and 2015. Further, we use the kernel density estimation, Gini coefficient, Theil index, logarithmic deviation and gravity standard ellipse to explore the spacial evolving characteristics and distribution patterns of ecological civilization construction efficiency connotation in China. The results show that: (1)There is obvious spatial disequilibrium in the efficiency of ecological civilization construction in China. During the study period (2003-2015), the spatial disequilibrium decreases gradually and then increases gradually. According to the mean Theil indexes in the three regions of China, the western region has the biggest spatial disequilibrium degree (0.1174), followed by the eastern (0.0365) and central China (0.0223). (2) Judged by the moving track of gravity center, the gravity center of China's ecological civilization construction efficiency, located in Henan province, has moved to the southeast and then to the northeast. The moving direction of gravity center shows the increase of ecological civilization construction efficiency in space. (3) Judged by the gravity standard ellipse, the spatial distribution of China's ecological civilization construction efficiency shows a pattern inclined northeast to southwest, and has the trend of a shift to right north and south.

Key words: ecological civilization construction efficiency, spatial equilibrium, pattern evolution, SBM model, kernel density estimation, center of gravity standard deviation ellipse
