目的 基于国家卫生服务调查数据,核算估计陕西省特定区域居民人均卫生支出.方法 采用小区域Fay-Herriot模型,估计2013年陕西省32个样本县/区和陕北、关中、陕南3个地域以及城乡居民的年人均卫生支出和误差,并分析相关影响因素.结果 陕西省城市和农村人均卫生支出估计值分别为625元、463元,陕北、关中、陕南人均卫生支出估计值分别为596元、520元和473元.影响居民人均卫生支出的主要因素是城乡地区（陕北、关中、陕南）差异.Fay-Herriot模型拟合的对数似然函数绝对值分别为37.18,66.19,10.88.结论 小区域直接估计和拟合Fay-Herriot模型方法,可获得特定区域的人均卫生支出估计值.采用地区、城乡差异模型较为准确核算出陕西省居民人均卫生支出,可为区域卫生管理决策或其他同类研究提供参考.

英文摘要：

Objective To estimate the health expenditure per capita of the residents in specific areas of Shaanxi Province based on the national health service survey data. Methods Small-area Fay-Herriot model was built to estimate the annual health expenditure per capita in 32 sample counties / districts of Shaanxi province and three regions （Northern Shaanxi, Guanzhong, and Southern Shaanxi）, as well as that of urban and rural residents and any possible errors, and analyze the relevant influencing factors. Results The estimated urban and rural health expenditure per capita in Shaanxi Province was CNY 625 and CNY 463; the health expenditure per capita in Northern Shaanxi, Guanzhong, and Southern Shaanxi was CNY 596, CNY 520 and CNY 473, respectively. The main influencing factor was the difference among the urban and rural areas and that among the different regions （mainly Northern Shaanxi, Guanzhong, and Southern Shaanxi regions）. The absolute value of log likelihood function fit in Fay-Herriot model was 37.18, 66.19, and 10.88, respectively.Conclusion Small-area direct estimation and Fay-Herriot model fitting can be used to estimate the health expenditure per capita in a specific area. By use of the regional and urban-rural difference model, the health expenditure per capita of Shaanxi residents can be calculated accurately, which can provide reference for regional health management decision making and other similar studies.
