为研究OFDI对中国碳排放的影响,使用2004—2019年省际空间面板数据对此进行了实证检验。SDM模型检验发现,OFDI会增加碳排放,且存在空间直接效应和空间溢出效应。稳定性检验证实了该结论。GTWR模型检验发现,OFDI对碳排放的影响存在明显的时空异质性:在碳排放时间演化检验中发现,OFDI增加碳排放的效应随着时间推移而逐年减弱,2016年以后,至少75%的省份OFDI导致碳排放显著减少,并且这种减少效应呈逐年增强趋势;在碳排放空间分布检验中发现,OFDI导致碳排放减少的省份随时间推移而不断增加,绝大多数省份OFDI导致碳排放减少的效果随时间推移而显著提高。为此,从研究期内综合整体看,OFDI会增加碳排放,但从时间演化和空间分布看,OFDI显著有利于抑制中国碳排放。

针对隧道工人职业健康风险缺乏定量评价方法的现状,借鉴公共环境健康领域暴露评价模型对隧道施工PM10职业暴露的健康风险进行定量评价.设计职业暴露问卷对湖北麻竹高速公路某标段施工中的250名隧道工人进行了调查,并对现场PM10浓度水平进行了监测.结果表明,隧道工人的PM10暴露浓度水平相当高,开挖工、爆破工、支护工、出渣工、二衬工的PM10暴露浓度分别为限值的83倍、18倍、8倍、9倍和9倍;5个工种比较,二衬工日均暴露时间最长,达11.48 h·d-1,能量代谢率最高,达1 067.43 k J·(m2·h)-1,呼吸速率的计算结果显示除二衬工属于重度活动以外,其他4个工种均为中度活动;评价结果显示5个工种均存在健康风险,其中,PM10暴露浓度高是开挖工和爆破工危险系数高的主要原因,而二衬工危险系数高的原因则在于高劳动强度所致的较高的呼吸速率以及较高的日均暴露时间.降低隧道工人PM10健康风险可行的途径是通过配备合适劳动作业的呼吸防护用品从而降低PM10暴露浓度,另外可通过制定相应的职业规范设置合理的劳动年限从而减少持续暴露时间.
