基于长江经济带三大城市群 2011-2021 年空间面板数据,运用空间杜宾模型对数智融合影响碳排放绩效的空间效应进行实证检验,并展开异质性分析.结果表明:第一,2011-2021 年长江经济带三大城市群的数智融合和碳排放绩效存在空间相关性,且具有显著的空间溢出效应.第二,碳排放绩效具有正向空间溢出效应;数智融合不仅能够显著提升本地区碳排放绩效,还能够通过溢出效应对邻近地区碳排放绩效产生显著的负向影响.此外,外商投资、人力资本和政府支出强度都会对本地区以及邻近地区的碳排放绩效起到促进作用,金融发展水平对本地区的碳排放绩效具有正向影响,但对于邻近地区却具有负向影响.第三,数智融合发展对碳排放绩效的空间效应具有异质性,长江三角洲城市群的数智融合对碳排放绩效的影响显著为正,数智融合的碳减排效应最佳;长江中游城市群的数智融合对碳排放绩效的影响为负,但并不显著,数智融合的碳减排效应次之;成渝城市群的数智融合对碳排放绩效的影响显著为负,数智融合的碳减排效应未得到充分的释放.基于此,本文提出了相应提升碳排放绩效的政策建议.
The Spatial Effect of Digital-Intelligence Integration on Carbon Emission Performance—Taking the Three Major Urban Agglomerations along the Yangtze River Economic Belt as an Example
Based on the spatial panel data of the three major urban agglomerations along the Yangtze River Economic Belt from 2011 to 2021,the spatial Dubin model is used to test the spatial effect of digital-intelligence integration on carbon emission perform-ance,and analyze the heterogeneity.The results show that:first,the digital-intelligence integration and carbon emission performance of the three major urban agglomerations along the Yangtze River Economic Belt from 2011 to 2021 have spatial correlation and significant spatial spillover effect.Second,carbon emission performance has positive spatial spillover effect;digital-intelligence integration can not only significantly improve the local carbon emission performance,but also produce significant negative effect on neighboring carbon e-mission performance through spillover effect.In addition,foreign investment,human capital and government expenditure intensity all promote the carbon emission performance of the local region and the neighboring regions,while the level of financial development has a positive impact on the carbon emission performance of the local regions,but it has a negative impact on the neighboring regions.Third,the spatial effect of the influence of digital-intelligence integration development on carbon emission performance is heterogeneous.The effect of digital-intelligence integration in the Yangtze River Delta urban agglomeration on carbon emission performance is significantly positive,and the carbon emission reduction effect of digital-intelligence integration is the best;the effect of digital-intelligence integra-tion on carbon emission performance in the middle reaches of the Yangtze River is negative but not significant,and the carbon emission reduction effect of digital-intelligence integration is the second most important;and the effect of digital-intelligence integration on car-bon emission performance in Chengdu-Chongqing urban agglomeration is negative,and the carbon emission reduction effect of digital-intelligence integration is not fully released.Based on this,some policy suggestions are proposed to improve carbon emission perform-ance.
