能源结构、雾霾污染与城市居民健康支出关系研究

Study on Relationship Between Energy Structure,Haze Pollution and Health Expenditure of Urban Residents

文章以2002年-2018年30个省、自治区、直辖市的数据为基础,首先基于面板向量自回归模型对中国影响居民健康支出的主要影响因素进行实证分析。其次采用面板门槛模型实证检验能源消费和能源结构在雾霾污染对居民健康支出的影响中是否存在门槛效应。研究结果表明能源消费、能源结构、经济发展水平、环境污染是影响居民健康水平的重要因素。随着能源消费总量的增加和第二产业占GDP比重的增加,PM_(2.5)浓度对居民健康支出的影响都存在单一门槛效应。同时,由于不同省际间能源消费和能源结构存在差异,也会影响各省份居民健康支出。

Based on the data of 30 provinces,autonomous regions,and municipalities from 2002 to 2018,this paper conducts an empirical analysis of the main influencing factors that affect residents'health expenditure in China based on the panel vector auto-regressive model.The panel threshold model is used to test whether energy consumption and energy structure have a threshold effect in the impact of haze pollution on residents'health expenditure.The research results show that energy consumption,energy structure,economic development level,and environmental pollution are important factors that affect the health of residents.With the increase in total energy consumption and the increase in the proportion of the secondary industry in GDP,the impact of PM_(2.5) concentration on residents'health expenditure has a single threshold effect.At the same time,it will also affect the health expenditure of residents in each province due to differences in energy consumption and energy structure between different provinces.
