generally speaking, the repayment sources of a company's PPP projects mainly include: 1. operating income (sales income). 2. Bank loans. 3. sale of assets

expansion if the PPP project is a government-paid or feasibility gap subsidy project, the government's financial resources are the main reference for project investment and the source of repayment when the project enters the operation period, which is very important. Here, we should pay attention to the government's financial resources, which are available to the government, mainly including general budget revenue, general transfer payment revenue in transfer payment, higher-level return income, government fund revenue and state-owned capital operational income, but generally excluding special transfer payment, because special transfer payment involves the special use of project funds, and the government cannot control it at will to repay government debts.
