摘要
基于2008-2021 年全国30 个省市区的面板数据,运用中介效应检验模型,实证研究城镇化是否会通过产业集聚影响农业碳排放,并进一步通过面板门槛模型研究城镇化对农业碳排放的作用是否会受产业集聚程度的影响.结果表明:城镇化对农业碳排放有显著的正向影响,城镇化水平越高,越会加剧农业碳排放;产业集聚在城镇化对农业碳排放的影响中具有重要的中介作用,城镇化会促进产业集聚进而增加农业碳排放;城镇化对农业碳排放的影响,受产业集聚的单一门槛效应的影响,当产业集聚程度跨越门槛值后,城镇化对农业碳排放的正向促进作用成倍减少.
Abstract
Based on the panel data of 30 provinces and cities in China from 2008 to 2021,this paper empiri-cally studies whether urbanization will affect agricultural carbon emissions through industrial agglomeration by using the intermediate effect test model,and further studies whether the effect of urbanization on agricultural carbon emis-sions will be affected by the degree of industrial agglomeration by using the panel threshold model.The results show that urbanization has a significant positive impact on agricultural carbon emissions,and the higher the level of ur-banization,the more severe agricultural carbon emissions will be;industrial agglomeration plays an essential inter-mediary role in the impact of urbanization on agricultural carbon emissions.Urbanization will promote industrial ag-glomeration and thus increase agricultural carbon emissions;the impact of urbanization on agricultural carbon emis-sions is affected by the single threshold effect of industrial agglomeration.When the degree of industrial agglomera-tion crosses the threshold value,the positive promoting impact of urbanization on agricultural carbon emissions is reduced exponentially.
