Anhui Chizhou sewage treatment PPP project is a natural monopoly project, and the expected profit is guaranteed. More importantly, Shenzhen Water Group, the winner of the social capital of the project, holds 80% of the shares of the project, while Chizhou Water Supply Company only holds 20%. Therefore, the first PPP project of the Ministry of Finance deserves more attention from social capital, private capital and the whole society. This project is a typical example that is likely to attract social capital. It can create a large PPP project and attract more social capital and private capital to invest in infrastructure construction and other state-owned projects.
