Research on governance subjects and environmental evaluation based on a survey experiment.

Environmental governance has become an important part of China's national governance system, and public evaluation of the effects of environmental governance is essential to the theory and improvement of environmental governance. In the context of Public Private Partnership (PPP) reform, both government and enterprises are service providing subjects. Who can be trusted more? And who can improve the public evaluation of environmental governance? These questions have not been answered in the existing research. This research conducted a survey experiment and took the sanitation reform of City H as an example to explore the influence of different governance subjects on environmental governance evaluation, and verified the mediated effect based on the KHB method. The results showed that, first of all, the respondents who received the intervention of enterprise governance text had a higher environmental governance evaluation, rating 0.110 5 higher than the government. Secondly, public trust in enterprises had a mediated effect, with 25.48% contributed from the effect between governance subjects and environmental governance evaluation. Thirdly, the perception of environmental performance also played a mediated role with 17.98% of its effects. Finally, media use also had a positive mediated effect. This article suggests that PPP reform should give more priorities to enterprises. The government should strengthen its involvement in financing, bidding, operation and regulation. It also needs to improve information transparency and media publicity. [ABSTRACT FROM AUTHOR]
