摘要:

环境质量对城镇居民医疗支出有着重要影响。本文基于2003~2011年全国31个省市自治区的统计数据,选取人均医疗支出、人均收入、废气排量、固体垃圾作为研究变量,利用系统聚类分析原理,对各地区进行分类,分别建模,进而分析影响不同地区城镇居民医疗支出的主要因素,探讨环境污染与医疗支出的数量关系。实证结果表明:居民医疗支出会因地区不同而变化,人均收入高的地区医疗支出也相应较高,并且人均医疗支出与废气排量呈正相关关系,规范、及时处理固体垃圾会使医疗支出相应减少。

Abstract: The environmental quality has a vital influence on the health expenditure of urban residents. Based on statistical data of 31 provinces in China from 2003 to 2011, in which the per capita health expenditure, per capita income, exhaust emissions and solid waste are selected as study variables, the main factors affecting health expenditure of urban residents in different areas are analyzed and the economical relationship between environmental pollution and health expenditures is explored using cluster analysis method and modeling process. The empirical results show that: health expenditure of residents varies from region to region, and the region with higher per capita income has a higher health expenditure. At the same time, per capita health expenditure and exhaust emissions have a positive correlation and standardized and timely treatment of solid waste will reduce health expenditure.
