本课题基于Barro政府支出模型和Grossman家庭健康投资模型，结合空间面板计量模型，构建地方政府居民基本医疗保险筹资竞争行为机理与识别框架。在此框架下展开以下三个方面研究：一是从时间维度上，利用复杂网络分析方法和动态随机一般均衡模型（DSGE），系统分析地方政府筹资竞争对居民基本医疗保险筹资的传导机制；二是从空间维度上，拓展地方政府居民基本医疗保险筹资竞争理论模型，将商业健康保险纳入进去，结合空间截面计量模型，设计筹资竞争下居民基本医疗保险筹资与商业健康保险衔接框架；三是在时空两个维度分析的基础上，从厘清地方政府在居民基本医疗保险中的筹资边界，及居民基本医疗保险筹资与商业健康保险的衔接，对居民基本医疗保险筹资机制提出优化方案。

Based on the Barro government spending model and the Grossman family health investment model, this subject used the spatial panel econometric model to construct a competitive behavior mechanism and identification framework for local government in residents' basic medical insurance financing. In this framework, the following three aspects were studied: Firstly, from the time dimension, using the complex network analysis method and the dynamic stochastic general equilibrium model (DSGE), we systematically analyzed the transmission mechanism of local government financing competition to the residents’ basic medical insurance financing; Secondly, from the spatial dimension, we expanded the theoretical model of local government financing competition in residents’ basic medical insurance with incorporating commercial health insurance, and combined the spatial cross-section econometric model to design the connection framework for the financing of residents’ basic medical insurance and commercial health insurance under the financing competition merchanism; Lastly, based on the two-dimensional analysis of time and space, we clarified the financing boundary of local government in residents' basic medical insurance and the connection between residents' basic medical insurance financing and commercial health insurance. We also proposed an optimization plan for the residents’ basic medical insurance financing mechanism.
