摘　　要：以第三方环境信息披露政策为准自然实验,采用双重差分法模型考察了非正式环境规制政策对企业污水排放的影响作用。结果表明,第三方环境信息披露政策不仅减少了企业污水排放量,而且削弱了企业污水排放强度;第三方环境信息披露政策通过提升公众环境关注度、政府环境治理水平等渠道促进了企业污水排放量的减少;异质性分析发现,第三方环境信息披露政策对经济发展水平较高的城市、高耗水行业、国有企业的污水排放产生了明显的削减作用;城市数字经济发展和绿色信贷在增强第三方环境信息披露政策的污水减排效应中发挥了重要作用。建议加大环境信息公开力度,促进数字经济发展和绿色信贷顶层设计,并提出了从非正式环境规制角度促进企业减排降污的新思路。Based on a quasi-natural experiment of third-party environmental information disclosure policy,this study employs the Difference-in-Differences(DID)model to investigate the impact of informal environmental regulation policies on enterprise sewage discharge.The findings demonstrate that the third-party environmental information disclosure policy not only reduces corporate sewage discharge but also mitigates its intensity.A series of robustness tests confirm the reliability of these results.The third-party environmental information disclosure policy promotes a reduction in enterprise sewage discharge by enhancing public awareness of the environment and improving the government’s capacity for environmental governance.Heterogeneity analysis reveals that third-party environmental information disclosure has a more pronounced effect in reducing sewage discharge in cities with higher levels of economic development,industries with high water consumption,and state-owned enterprises.Urban digital economy development and green credit play crucial roles in augmenting the effectiveness of third-party environmental information disclosure policies in curbing sewage emissions.This article suggests intensifying efforts to disseminate environmental information while promoting digital economy growth and implementing top-level designs for green credit systems.By adopting an approach centered around informal environmental regulation,this paper presents a novel idea to promote emission reduction and pollution control among enterprises.
