Cooperative Medical System

This dissertation mainly research in the field of medical protection mechanism in the rural China, particular about the institution of CMS. The research work consists of theoretical part and empirical one. If given space and time location, the empirical research is about two township CMS institutions in south of and north of Jiangsu province since 1990s, this two CMS is different phenomenally: one evolutes from 1950s and has long tradition, the other is constructed since 1992; one looks like alluding transformation, the other like compulsory change. Nevertheless, they all face with serious crisis.In order to analysis the problem, we would rather to search for some theoretical instruments before beginning our empirical research. To this topic, there is no mature sociological theory, even a systematical one, so I would have to put hands to the economics or political theory. If the feature of sociological research is comprehensive, empirical and scientific, this study is sociological one. Because CMS is known as one kind of primary insurance institution, we would research in the fields of institution analysis, social protection, medical insurance. In the aspect of institution analysis, we try to find fitful general method to analysis the institutional change of CMS. In social protection aspect, we want to find the principals of social security and social insurance, and what is fitful aim of health protection institution. In medical insurance, we attempt to draw an trying decision-making model of Chinese peasants.From view of game theory, the institution is the outcome of game of participants in condition of given conditions. Therefore, we investigate the three participants: CMS manager, rural medical servers and local people, which is the demander of medical service and CMS payer. After the investigation and analysis, the dissertation would give an explanation of CMS change in two different local contents.This dissertation falls into eight chapters.1st chapter is the introductory part, which is devoted to briefing the research backgrounds, status, intention, possible meaning.The 2nd chapter is about the topic, basic concepts and analysis frameworks of social protection mechanism.
