The PPP（Public-Private Partnership） model generally assumes the design，construction，operation，and maintenance of PPP projects by social capital，and generates profitable non-profitable investment returns through user fees，government payments，and financial feasibility gap subsidies. The government department is responsible for the whole process supervision，and the government and social capital share the whole process risk.
