中国地区间健康差异的因素分解

Analysis of Regional Differences in Health in China

基于我国9个省份的微观数据,以成年人标准化的身体质量指数(BMI)和自评健康作为健康的代理指标,利用Oaxaca分解和Fairlie非线性分解技术,分析了影响我国东、中、西部地区健康差异的因素,并得出以下结论:各区域间均存在显著的身体质量指数差异,其中,东部居民与西部居民的身体质量指数差异最大,并呈现逐年上升的趋势;各区域居民身体质量指数差异的要素差异主要以婚姻状况、家庭规模、职业、生活环境及医疗资源为主,而年龄分布、家庭规模、教育程度、收入和医疗资源对各区域居民自评健康机率差异有显著影响。因此,改善这些影响地区间居民健康差异的主要因素,将会缩小地区间的健康差异。

Using micro-data from 9 provinces of china,standard Body mass index（BMI） and Self-assessed health（SAH）,this paper exploree the factors that account for the regional differences in health in China.The author applies Oaxaca decomposition and Fairlie non-linear decomposition for the analysis.The empirical results show that the differences in health among each area are statistically significant.The differences in BMI between west and east is the biggest,the BMI gap is widen by year.The author finds that martial status,household size,occupation,environment and medical resources are important determinants of the BMI gap,while the age,household size,education,income and medical resources affect the SAH gap.The health inequality across regions can therefore be narrowed if gaps in these factors alleviated.
