摘　　要：鼓励政府和社会资本合作(PPP)开展养殖污水治理,是帮助养猪大户在保供给与保环境的“两难”之间谋求“两全”的重要路径。该研究以养殖污水处理PPP项目为例,从同行交流、同行互惠与同行信任三个维度检验了同行社会资本对养猪大户环境治理行为决策的影响。研究发现:①71.3%的受访养猪大户具有参与养殖污水处理PPP项目的积极性,其“愿意”为每头生猪支付的养殖污水处理平均费用约为16.7元。②同行社会资本对养猪大户养殖污水处理PPP项目参与意愿、意愿支付水平具有显著促进作用。其中,同行交流、同行互惠有助于改善养猪大户的参与意愿;同行互惠、同行信任则能提高其意愿支付水平;这一结论经过一系列的稳健性检验后依然成立。③进一步的异质性分析则表明,在村外进行养殖的养猪大户受同行交流影响更为显著,低学历、从业时间短、家庭人口数量较多的养猪大户更容易受到同行互惠的影响,高学历、从业时间长、在村外进行养殖的养猪大户则对同行信任更为敏感。基于此,提出:①地方政府可尝试在充分评估地方财政能力、进一步明晰回报机制和私营部门参与PPP项目责任边界的基础上,采用整体委托或是分阶段建设的形式推广养殖污水处理PPP项目。②通过在区域内构建生猪养殖行业沟通互动平台、定期举办生猪养殖经验分享会等方式,积极培育同行社会资本,拓宽养猪大户获取信息、资源的渠道。③以因户制宜、分类指导为基本原则,制定差异化的政策措施鼓励不同类型的养猪大户参与养殖污水处理PPP项目。Encouraging public-private partnership(PPP) to carry out breeding sewage treatment is the vital way to help large pig farmers balance the dilemma of ensuring the supply and protecting the environment. Taking the sewage treatment PPP project as an example, this article explored the impact of peer social capital on the willingness of large pig farmers to pay for environmental governance from the three dimensions of peer communication, peer reciprocity, and peer trust. The results showed that:①71.3% respondents had the initiative to participate in the PPP project, and that they were willing to pay RMB 16.7 yuan for breeding sewage treatment of each pig.②Peer communication and peer reciprocity helped to improve the participation intentions of large pig farmers, while peer reciprocity and peer trust could improve their willingness to pay. These results still held after a series of robustness tests.③ Further heterogeneity analysis showed that large pig farmers farming outside the village were more influenced by peer communication, while large pig farmers with a low educational background, low work seniority, or large household population were more influenced by peer reciprocity.Large pig farmers with a high educational background, high work seniority, or farming outside the village were more influenced by peer trust. Based on these results, this article suggests that local governments should try to promote breeding sewage treatment PPP projects in the form of overall entrustment or phased construction on the basis of fully assessing local financial capacity, further clarifying the return mechanism and the responsibility boundary of private sector participation in PPP projects. Furthermore, governments should also actively cultivate peer social capital and broaden the channels for large pig farmers to obtain information and resources by building a communication and interaction platform for the pig breeding industry in the region and by regularly holding pig breeding experience sharing meetings. In addition, the go
