摘　　要：利用2007—2020年31个省(自治区、直辖市)面板数据,以企业加成率作为中介变量深入考察了污染密集型产业集聚对绿色全要素生产率(GTFP)的影响及其内在机制。研究发现:专业化集聚显著推升了GTFP,而多样化集聚显著抑制了GTFP;衡量市场竞争度的企业加成率在专业化集聚、多样化集聚与GTFP之间发挥的中介作用均显著为正;企业加成率与GTFP负相关,表明市场竞争有利于GTFP提升。进一步的分析表明,以企业加成率作为门限变量时,专业化集聚和多样化集聚对GTFP的影响分别存在双重门限和单一门限;在中西部地区,多样化集聚不利于GTFP提升、从而需要大力发展专业化集聚,在东部地区则相反。Using the panel data of 31 provinces(autonomous regions and municipalities directly under the central government) from 2007 to 2020,this paper takes the markups as the mediating variable to deeply investigate the influence of pollution-intensive industrial agglomeration on green total factor productivity(GTFP) and its internal mechanism.The research results show that specialized agglomeration significantly promotes GTFP,while diversified agglomeration significantly inhibits GTFP.The intermediary role of markups between specialized agglomeration,diversified agglomeration and GTFP is significantly positive.Markup is negatively correlated with GTFP,indicating that market competition is conducive to GTFP improvement.Further analysis shows that when markup is used as the threshold variable,there are respectively double thresholds and single thresholds on the impact of specialized agglomeration and diversified agglomeration on GTFP.In the central and western regions,diversified agglomeration is not conducive to GTFP promotion,so it is necessary to vigorously develop specialized agglomeration,while in the eastern region,it is the opposite.
