From the perspective of household consumption, this paper adopts the carbon emission coefficient method and consumer lifestyle method to calculate the carbon emission of community residents, and uses the super-efficiency DEA model to evaluate the community ecological efficiency, and finally identifies the influencing factors of ecological efficiency through econometric analysis. The results showed that:(1) the per capita carbon emission of community residents indicated the order of commercial housing community (528.85 kgCO2/month) > unit community (475.66 kgCO2/month) > traditional community (368.33 kgCO2/month); (2) The ecological efficiency presented the traditional community (111.04%) > commercial housing community (108.78%) > unit community (105.70%); (3) Willingness to participate in community management and household lighting conditions had positive effects on community ecological efficiency. In addition, the age structure (the proportion of young and middle-aged population) had a negative impact on the ecological efficiency of commercial housing communities, while the improvement of education level would improve the ecological efficiency. Furthermore, the transformational development strategies based on the characteristics of the three types of communities were proposed to provide a reference paradigm and decision support for the ecological transformation and low-carbon development of different types of communities in China. 参考文献 相似文献 引证文献
