基于2009—2021年16个煤炭资源型区域,聚焦于煤炭产业、生态环境与居民健康之间的关系,利用熵值法和中介效应模型对煤炭产业跨区转移给居民健康带来“惊喜”还是“隐忧”进行实证分析。研究发现:①煤炭产业经济发展不利于居民健康水平的提升,且呈倒“U”型的非线性关系;②生态环境在煤炭产业与居民健康关系中发挥部分中介作用;③煤炭产业对居民健康水平的非线性影响和生态环境的中介效应因煤炭跨区转移行为而存在差异,煤炭产业在跨区转入地区整体上促进了居民健康水平的提升,呈“U”型的非线性关系,而中介效应在煤炭跨区转入地区不再显著。

Based on the 16 coal resource-based regions from 2009 to 2021, focusing on the relationship between the coal industry,ecological environment and residents’ health, using the entropy method and the mediation effect model to analysis the impact the crossregional transfer of the coal industry will bring on residents’ health is “surprise” or “concealment” . The research results show that: (1) the economic development of the coal industry is not conducive to the improvement of the health level of the residents, and has an inverted “U-shaped” nonlinear relationship;(2) the ecological environment plays a partial mediating role in the relationship between the coal industry and the health of the residents;(3) The non-linear impact of coal industry on residents’ health and the mediating effect of ecological environment are different due to differences in coal transfer behavior across regions. Coal industry in the region where the crossregional transfer to the region promotes the improvement of residents’ health as a whole is in a “U-shaped” nonlinear relationship of coal,and the mediation effect is no longer significant in the coal transfer area.
