摘要
经济结构与发展水平对地区碳排放有重要影响.以淮海经济区为例,选取2005—2021年面板数据,将经济复杂度指数与碳排放量可视化,并运用固定效应模型探究经济复杂度对碳排放的影响.分析发现:经济复杂度指数高值经历了由“多点式”的零星分布到“组团式”的集聚形态;碳排放量高值区主要集中在济宁—宿州段,且逐渐向沿线聚集;经济复杂度指数对碳排放量呈现负显著关系,经济复杂度指数越高,碳排放量越低;经济复杂度对碳排放的影响呈现出显著的异质性,经济复杂度对非资源型县域的碳减排效应大于资源型县域.提高经济复杂度、多角度降低碳排放、加强政府监管和提高技术水平,可促进淮海经济区碳排放量减少.
Economic structure and development level have important influence on regional carbon emission.Taking Huaihai Economic Zone as an example,the panel data from 2005 to 2021 are selected to make economic complexity index and carbon emission visible,and the fixed-effect model is used to analyze the impact of economic complexity on carbon emission.The results showed that the high values of economic complexity index have gradually undergone a transition from scattered distribution in a"multi-point"manner to a"cluster"agglomeration pattern.The high values of carbon emission mainly located in Jining to Suzhou section,and gradually gathered along the line.There was a significant negative correlation between economic complexity and carbon emission,with higher economic complexity resulting in lower carbon emission.The impact of economic complexity on carbon emission showed significant heterogeneity,with the carbon reduction effect of economic complexity on non-resource-based counties greater than resource-based counties.Improving economic complexity,reducing carbon emissions from multiple perspectives,tightening government regulation,and improving technological capabilities can contribute to the reduction of carbon emissions in Huaihai Economic Zone.
