Ecological civilization construction is the new concept and trend of Chinas high quality development in new era,and it needs the collaborative propulsion of ecological economic civilization, ecological social civilization and ecological environment civilization. Reducing carbon emission intensity is an important issue facing Chinese government in the background of global warming. Studying the influence of ecological civilization construction to carbon emission intensity from different dimensions has important theoretical and practical significance. The influence of ecological economic civilization,ecological social civilization and ecological environment civilization to carbon emission intensity was empirically analysed by using China provincespanel data in 2004-2016 and spatial Durbin model based on STIRPAT model. The results show that: first,Morans I of China provincescarbon emission intensity was between 0. 425 ~ 0. 473. It shows obvious positive spatial correlation and illustrates that China provincescarbon emission intensity can influence each other. The reasons include the close ties between neighboring province and the similarity of natural,economic and social characteristics. Second,the correlation coefficients of ecological economic civilization,ecological social civilization and ecological environment civilization to carbon emission intensity were as follows:-4. 743 139,2. 865 884,-0. 324 644 7. It illustrates ecological economic civilization and ecological environment civilization can reduce carbon emission intensity,while ecological social civilization can increase carbon emission intensity. To reduce carbon emission intensity by ecological civilization,three subsystems of ecological civilization needs to produce negative influence to carbon emission intensity,the effect of ecological social civilization on carbon emission intensity needs to be changed,and thus we can realize the total reduction of carbon emission intensity. Third,ecological social civilizations spatial spillover effect cannot pass the significance test. The correlation coefficients of spatial spillover effects of ecological economic civilization and ecological environment civilization were 2. 046 531 and-3. 238 323 respectively. It illustrates that the improvement of ecological economic civilization can cause the increase of carbon emission intensity of the periphery provinces,while the improvement of ecological environment civilization can promote the reduction of carbon emission intensity of the periphery provinces. Enhancing cooperation between periphery provinces and establishing trans-provincial reducing carbon emission cooperation mechanism are needed.
