“双碳”目标下产业集聚与中国绿色经济空间收敛

Industrial Agglomeration and Spatial Convergence of Green Economy in China with the“Double Carbon”Goal

绿色经济增长是实现中国“双碳”目标的根本保障,而产业集聚对于地区绿色经济增长及中国绿色经济收敛起到重要作用。论文将产业集聚分为专业化、无关多样化和相关多样化三种模式,通过构建空间杜宾模型,采用2005—2019年省级面板数据,分析不同模式产业集聚对中国绿色经济收敛的影响。结果显示:(1)专业化集聚和相关多样化集聚呈现上升趋势,无关多样化呈下降趋势。(2)产业集聚有助于推动绿色经济收敛,绿色纯技术效率为主要影响路径。(3)无关多样化集聚能够促进本地区绿色经济增长,相关多样化具有抑制作用;专业化集聚和相关多样化集聚对邻近地区绿色经济增长具有负向空间溢出效应。(4)不同模式产业集聚均促进了八大地区的绿色经济收敛,南部沿海、东北地区和长江中游收敛速度最快。

Green economic growth is the fundamental guarantee to achieve the“double carbon”goal,and industrial agglomeration plays an important role in regional green economic growth and its green economic convergence(GEC)in China.Industrial agglomeration is divided into three modes:specialization,irrelevant diversification and related diversification,A SDM is constructed by using panel data of 30 provinces from 2005 to 2019 to analyze the effects of industrial agglomeration on China’s GEC.The results show that:(1)specialized and related diversification agglomeration show an upward trend,irrelevant diversification a downward trend.(2)Industrial agglomeration promotes GEC and GPTE is the main influence path.(3)Irrelevant diversification agglomeration increases GEE while related diversification has an inhibitory effect;specialized agglomeration and related diversification agglomeration have negative spatial spillover effects on GEE in neighboring regions.(4)Industrial agglomeration promote GEC in eight regions and the convergence speed of southern coast.The northeast region and the middle reaches of Yangtze River is the fastest.
