Agricultural non-point pollution has become a hot topic of social concern, and the three major industries in modern rural areas gradually tend to integrate. An in-depth study of the impact of rural industrial integration on agricultural non-point pollution has important guiding significance for the realization of sustainable agricultural development. Based on the panel data of 30 provinces and municipalities in China from 2011 to 2019, this paper explores the impact of rural industrial integration on agricultural non-point source pollution and further examines the moderating effect of urbanization. The main findings are as follows. First, there is a significant inverted U-shaped relationship between rural industrial integration and agricultural non-point source pollution. At present, rural industrial integration has a tendency of alleviating agricultural non-point source pollution. Second, urbanization has a moderating effect on the impact of rural industrial integration on agricultural non-point source pollution, moving the turning point of the curve to the left, which can accelerate the arrival of the emission reduction effect of rural industrial integration. Finally, the heterogeneity test shows that compared to areas with developed economies and weak financial support, the inverted U-shaped relationship between rural industrial integration and agricultural non-point source pollution is more significant in regions with underdeveloped economies and strong financial support. The above studies enrich the relevant literature on rural industrial integration and agricultural non-point source pollution and provide a theoretical basis for the government to formulate relevant policies for promoting the development of rural industrial integration and alleviating agricultural non-point source pollution.

The influence of informal employment on residents’ happiness has gained wide attention around the world. However, few studies focus on this topic in China. Using the 2016 wave of the China Labor Force Dynamics Survey (CLDS) data, we examined the effect of informal employment and its mechanisms on residents’ happiness in China. Our study shows there is a significant negative correlation between informal employment and residents’ happiness in China. Moreover, the correlation between informal employment and residents’ happiness is stronger for residents who are female, migrating, and with a rural household registration. In addition, we investigated possible mechanisms of the effect, including individual income, social respect, unemployment expectations, and social security, and found that informal employment reduces the happiness of residents by widening the gap in unemployment probability and social insurance level among residents.
