摘　　要：针对城市规模对医疗公共品供给的影响,使用35个大中城市1996-2015年地市级面板数据开展了分析研究。发现中国医疗公共品供给存在三个特征事实,用Hausman-Taylor方法与IV-2SLS估计显示,城市医疗公共品的供给会逐渐增加,但当城市规模上升到某个拐点时,医疗公共品的供给就不再增加了,即存在一个门槛效应。文中为未来的医改政策制定以及实施提供参考。Aiming at the influence of city size on the supply of medical public goods,this paper uses the panel data of 35 large and medium-sized cities from 1996 to 2015 to carry out analysis and research.It is found that there are three characteristic facts in the supply of medical public goods in China.Hausman-Taylor method and IV-2SLS estimation show that the supply of urban medical public goods will gradually increase,but when the city scale rises to a certain turning point,the supply of medical public goods will no longer increase,that is,there is a threshold effect.In order to provide reference for the formulation and implementation of future medical reform policies.

关 键 词：城市规模 医疗公共品 门槛效应
