市场结构、医武竞争与医疗费用增长:基于跨省数据的实证研究

Market Structure, Medical Arms Race and Health Expense Growth: An Empirical Analysis Based on the Cross-province Data

目的:分析医院非价格竞争行为与市场结构之间的关系,研究医院市场结构与医疗费用增长之间的关系。方法:利用SCP理论,建立卫生费用支出、医院市场集中度和公立医院市场占有率的回归方程,利用面板数据的双因素效应模型进行实证分析。结果:在目前的市场集中度条件下,医院产业不存在医武竞争。结论:市场竞争的加剧对于提高医院效率的作用,远远超过医院产权差异和盈利属性。

Objective： To analyze the relationship between hospital non-price competition behavior and market structure, analyze the relationship between hospital market construction and health care costs growth. Methods： Using cross-province data（SCP） theory to establish the regression function of health cost expenditure, hospital market concentration ratio and the occupancy of public hospital market, process the empirical analysis based on the two-factor effectiveness model of panel data. Results： There is no medical arms race in hospital business under the current market concentration. Conclusion： The reinforcement of market competition played a more important role in the improvement of operational efficiency rather than the differences in the nature of property rights and the profit of hospitals.
