As an important component of urban construction, the community sustainable construction is of great significance to the social development. Despite the importance of the social dimension of community sustainability, it has received relatively little attention when compared to the sustainability of environmental and economic dimensions. Based on the literature review, it is found that the social dimension of the sustainable community, such as residents’ psychological feelings, social capital, has a strong effect on the sustainability of communities. This paper, therefore, conducts an empirical study on the mediating role of emotion experience on the associations between social capital and life satisfaction. Research on the relationship between them can help to generate synergies and strengthen the effect of promoting community sustainable development. A total of 229 complete responses from residents in China is used for data analysis. Results from the multiple linear regression analysis indicate that social capital has the significant positive effect on life satisfaction; the influence of social capital on life satisfaction is partly mediated by positive and negative affect, the social capital improves the life satisfaction through promoting positive affect, while it enhances the life satisfaction through restraining the negative affect. Based on the relationship between them, the relevant recommendations for the measures on the sustainable community can be proposed.

As an important component of urban construction, the development of the community is of great significance to the sustainable construction of the entire society. The previous studies mainly focused on quantitative research and were limited by the data collectability, affecting the scientificity of the index system. Therefore, based on the theory of sustainable development, through the review of previous literature, combined with relevant experts' opinions and community development goals and other factors, a qualitative evaluation index system for community sustainable development capacity was established. The ANP (analytic network process) method is mainly used to determine the weight of each indicator, and FCE (fuzzy comprehensive evaluation) is proposed to determine every indicator’s membership. Then the hybrid fuzzy evaluation is promoted to evaluate the selected community as the empirical study. In this paper, the indicator selection is not limited by objective factors, and the evaluation system is more accurate; the application of ANP method makes the results of weight more scientific; meanwhile, fuzzy comprehensive evaluation can be suitable for solving various nondeterministic problems. This study transforms qualitative research into quantitative research; it provides an effective evaluation method for local managers and decision makers to carry out community sustainable construction.
