基于2003~2012年18个中西部省市的面板数据,利用空间计量模型分析污染密集型产业转移承接对中西部省份居民健康成本支出的影响。实证结果表明,中西部地区承接污染密集型产业有助于降低居民健康成本支出,其中,中部地区降低效果较为显著,西部地区并不显著;收入增长提高了中西部居民的总体健康支出,但西部居民的收入健康支出弹性显著大于1,表明西部居民收入增长的健康支出效应大于收入效应。此外,受区域间治理不平衡及低效治理等因素影响,虽然中西部地区加大了污染治理强度,但并未显著降低中西部居民健康成本支出。
Based on the panel data of 18 central and western provinces and municipalities from 2003 to 2012, the spatial econometric model was used to analyze the impact of transfer of pollution-intensive industries on the health cost of residents in central and western provinces. The empirical results show that undertaking pollution-intensive industries in the central and western regions will help to reduce the residents’ health cost. Among them, the reduction effect in the central region is significant, but not significant in the western region. The increase in incomes will increase the overall health expenditure of residents in the central and western regions. However, Residents’ income elasticity of health expenditure is significantly greater than 1, indicating that the health expenditure effect of income growth in the western region is greater than the income effect. In addition, affected by the imbalance among regions and inefficient governance, the intensity of pollution control in the central and western regions did not significantly reduce the health cost of residents in the central and western regions.
