PPP is the abbreviation of English private-public-project, which means that the government, public and private sectors cooperate to complete infrastructure investment and construction to meet the needs of cities for infrastructure. Many infrastructures are public welfare. If there is no integration and investment value, it is difficult to use private capital for construction. PPP will commercialize these projects with no commercial investment value. During the operation of the project, private institutions will be able to recover their investment and earn profits, while the government will pay the least price for the project.
