Objective To explore the utilization of health services and its influence factors from 1999 to 2014 in Beijing. Methods The descriptive statistics on the number of treated patients and in-patients, structure of population ages, the per capita disposable income and other factors were given. Regression analysis was used to analyze the quantitative relationships between the indicators and the influence factors of health services utilization. The threshold values of the significant influence factors were given by using the threshold test, and the correlation coefficients of the data sequence were calculated. Results The per capita disposable income, population density and per capita highway mileage affected the health services utilization significantly. The structure of population age and the proportion of public health expenditure affected the number of patients treated significantly. The per capita disposable income and population density had significant threshold value, and the relationships between them and health services utilization were stronger when they were more than the threshold values. Conclusion In order to improve the health services utilization, the aging population, population density and city expansion should be paid more attention. The per capita disposable income and the proportion of public health expenditure should be increased.%目的 了解北京市在1999～2014年间卫生服务利用的状况以及影响因素.方法 采用描述统计法对医院的治疗人次、入院人数等卫生服务利用指标和年龄结构、人均可支配收入、公共卫生支出占财政总支出比例等影响因素进行描述,使用回归分析给出卫生服务利用各指标与影响因素之间的定量关系,运用门限检验给出显著性影响因素的门限值,并计算数据序列的相关系数.结果 人均可支配收入、人口密度、人均公路里程数显著影响卫生服务利用各指标,年龄结构、公共卫生支出占财政总支出比例显著影响入院人数.人均可支配收入和人口密度有显著的门限制,并且超过门限值后它们与卫生服务利用的关系加大.结论 关注人口的老年化、人口密度和城市的扩建,提高人均可支配收入以及公共卫生支出占财政总支出比例,不断改善卫生服务利用.
