It is not a policy that stipulates that these projects have an operating cycle. It does not mean that once you invest the funds, you can get all the funds back immediately. Moreover, PPP projects involve relatively large funds, so the return period will be longer. PPP is the abbreviation of Public-Private-Partnership, which refers to the government.

Between Public and Private, based on the starting point of providing products and services, a franchise agreement is reached to form a partnership of "maximum benefit sharing, maximum risk sharing, and full cooperation". The advantage of PPP is that it allows all parties to achieve greater results than would be achieved individually.

The action anticipates more favorable outcomes: less fiscal spending by the government and less risky investments by companies.
