With the development of the rural economy,the change of rural lifestyle and the improvement of consumption level,the total discharge of rural domestic sewage has shown a continuous upward trend,which not only destroys the public environment in rural areas,but also has a certain degree of impact on the health of villagers.In recent years,with the joint efforts of relevant departments,rural domestic sewage treatment has achieved certain results,but it still faces problems such as the lack of governance subjects,the low willingness of villagers to participate,and insufficient capital investment.Villagers are the direct dischargers of rural domestic sewage,but also the participants and beneficiaries of domestic sewage treatment,how to guide villagers to participate in domestic sewage treatment,is the key to solving the problem of rural domestic sewage treatment.Social capital is the key factor affecting the governance of the public environment and forming collective action,and social trust,as one of the main contents of social capital,is an important factor affecting the participation of villagers in the governance of public affairs.Based on the survey data of 285 villagers in Yuanjiang City,Hunan Province,this paper uses the binary Logit model to explore the influence of social trust on the villagers’ willingness to participate in domestic sewage treatment from the perspective of social trust.The following conclusions are mainly drawn:(1)The trust in social trust in the government,village cadres,environmental protection regulations,relatives,and neighbors has a significant role in promoting the willingness of villagers to participate in domestic sewage treatment,and it is still significant after excluding the sample of the elderly.(2)Both the institutional trust factor and the interpersonal trust factor constructed by the principal component factor analysis method significantly promote the villagers’ willingness to participate in the treatment of domestic sewage,and the influence effect of the institutional trust factor is higher than that of the interpersonal trust factor.(3)The degree of gender and policy awareness in the control variables has a significant positive impact on the villagers’ willingness to participate in domestic sewage treatment,while the villagers’ evaluation of water quality has a significant negative impact on the villagers’ willingness to participate.(4)Villagers who have not installed three(four)septic tanks in their homes are willing to participate in domestic sewage treatment and are significantly positively affected by both institutional trust and interpersonal trust,while the villagers who have been installed at home are only significantly positively affected by interpersonal trust,and the impact of institutional trust is no longer significant.cted by interpersonal trust,and the impact of institutional trust is no longer significant.Based on the above research conclusions,this paper puts forward the following suggestions:(1)To give play to the significant advantages of institutional trust in promoting villagers’ willingness to participate in domestic sewage treatment.(2)Attaching importance to interpersonal trust plays an important role in promoting villagers’ willingness to participate in domestic sewage treatment.(3)Increase the publicity of domestic sewage treatment policies and improve the policy awareness of villagers.(4)Improve the rural domestic sewage treatment system,and strengthen the effective connection between toilet improvement and rural domestic sewage treatment. |
