摘　　要：采用Andsersen医疗服务利用模型研究医疗保险决策对医疗服务利用的影响,使用中国家庭收入分配调查数据中关于流动人口医疗服务利用调查年份的最新数据(CHIP2008),以年医疗支出作为医疗服务利用的代理变量,使用倾向得分匹配法(PSM)评估在消除选择性偏差和其他混杂偏差后流动人口参加医疗保险对其医疗支出的影响,结果表明:与我国其他群体相比,流动人口参保率较低;流动人口参加医疗保险会显著增加其医疗支出;流动人口参加医疗保险对其医疗支出的影响存在性别差异,与女性流动人口相比,医保对于男性流动人口医疗支出的促进作用更加显著。With the Andsersen medical service model, this paper tries to make a study on the impact of medical insurance de- cisions on the utilization of medical service. Based on the latest data on utilization of medical service on the part of floating population in the survey year which come from Chinese Household income distribution survey data （ CHIP2008）, with the an- nual medical expenditure as a proxy for the use of medical services, the paper makes a study on the decision of medical insur- ance and its impact on medical expenditures, by using propensity score matching （PSM） to wipe out the effect of selection bi- as and other mixed deviation. The empirical analysis shows that compared with other groups in our country, the rate of the floating population who has participated in the medical insurance is low, whose participation in the medical insurance will sig- niticanfly increase their medical expenditure. As far as the effect of the floating population＇s participation in medical insurance on their medical expenditure is concerned, there exist gender differences. Compared with the female floating population, medi- cal insurance plays a more important role in promoting the medical expenditure of the floating population.
