Research on Pricing of Green Elderly Care PPP Project Based on Bi-level Programming Model
In order to ensure scientific and reasonable subsidy and pricing decision-making of institutional elderly care public-private-partnership(PPP)projects,green orientation and pension subsidy were taken as the entry point of the research on pricing decision-making of institutional elderly care services,and the system of pricing influencing factors of institutional elderly care PPP projects under green orientation was constructed by combining with the characteristics of the industry.The models of government's supply-side subsidy and demand-side subsidy to elderly care institutions were constructed and solved based on the bi-level programming model.And sensitivity analysis and horizontal comparative analysis were carried out.Finally,the effectiveness and feasibility of the model were verified by software simulation analysis.The results show that:the intensity of government subsidies is positively related to project quality and social capital gains;there are advantage ranges in all the supply-side subsidies,and the choice of subsidy methods needs to be determined in combination with the development stage of the elderly care industry.the conclusion could optimize the subsidy pricing mechanism of green elderly care PPP projects and promote the green,healthy and high-quality development of the institutional elderly care industry.
