Information asymmetry exists in the quality governance in institutional elderly care services. To address this issue, this study constructs a tripartite game model involving institutional elderly care service providers, local government departments, and higher-level governments under the framework of governmentpurchased institutional elderly care services. The model conducts an in-depth analysis of the key factors influencing the behavioral strategies of these three stakeholders, aiming to address the governance challenges related to the quality of inclusive institutional elderly care services. The findings indicate that the strictness of quality governance by service providers, local governments, and higher-level governments largely depends on their respective governance efforts, governance costs, and the opportunity costs associated with governance. To safeguard the rights of the elderly in accessing quality care services, the government should efficiently fulfill its regulatory responsibilities, mitigate information asymmetry, and improve relevant governance systems and measures, thereby establishing a multi-stakeholder quality governance system for inclusive institutional elderly care services.
