环境质量对居民医疗保健支出的影响

The Impact of Environmental Quality on Household Health Care Expenditure

摘要: 将二氧化硫排放量作为环境质量的代理变量，用2006~2015年全国居民家庭人均医保支出、城乡居民人均可支配收入、城乡收入比、医保价格指数、CPI、参保比重数据，建立动态面板数据模型，在全国数据的基础上，分别探究三大地区居民人均医保支出和收入、环境间的关系。实证结果表明：二氧化硫排放量的增加，使人们增加对医疗服务的需求，医疗保健支出增多；其中，东部地区环境质量对医疗保健支出的影响最大,西部地区最小。

Abstract: This article sees the industrial sulfur dioxide emissions as a proxy for the quality of the environ-ment. Then, we collect per capita medical insurance spending of China’s residents, per capita dis-posable income of urban and rural residents, urban and rural income ratio, health care consumer price index, Consumer Price Index and the percentage of medical insurance from 2006 to 2015 to establish a dynamic panel data model. Based on the national data, we explore the relationship between per capita medical insurance spending of Chinese residents, annual income of residents and environmental quality in the three major areas. Empirical results show that with the increase in sulfur dioxide emissions, people increase the demand for medical services and the spending on health care will increase. In the eastern region, the impact of environmental quality on medical insurance spending is maximum, and the western region is minimum.
