【摘要】 在信息化时代背景下，数字产业集聚作为推动经济高质量发展的新突破口，是否也是生态环境改善的新契机?本文选取长三角区域41座城市2006～2023年的面板数据，运用固定效应模型、中介效应模型、调节效应模型以及空间面板模型实证检验数字产业集聚的环境污染治理效应及其作用机制。研究发现，数字产业集聚具有环境污染治理效应，且该效应具有空间溢出特征;数字产业集聚可以通过提升城市对外经济联系强度以及促进城市内部经济集聚进而改善城市环境质量;地方政府干预可以强化数字产业集聚的环境污染治理效应;数字产业集聚对环境污染的净化作用在二线及以上城市、PITI指数未公开城市以及“宽带中国”示范城市效果更优。最后，基于研究结论提出相关政策建议，对实现数字化和绿色化协同发展，推动中国可持续发展具有重要意义。更多还原

【Abstract】 In the context of the information age,is the clustering of the data industry a new breakthrough point for promoting high-quality economic development,and also a new opportunity for improving the ecological environment? We selected panel data from 41 cities in the Yangtze River Delta region from 2006 to 2023 and empirically tested the environmental pollution control effects and mechanisms of digital industry agglomeration using fixed effects model,mediation effect model,moderation effect model,and spatial panel model. Research has found that the agglomeration of digital industries has environmental pollution control effects,and this effect has spatial spillover characteristics; The agglomeration of digital industries can improve the quality of urban environment by enhancing the strength of urban external economic connections and promoting internal economic agglomeration; Local government intervention can strengthen the environmental pollution control effect of digital industry agglomeration; The purification effect of digital industry agglomeration on environmental pollution is more effective in second tier and above cities,cities with undisclosed PITI index,and demonstration cities of “Broadband China”. Finally,based on the research findings,relevant policy recommendations are proposed,which are of great significance for achieving the coordinated development of digitalization and greening and promoting sustainable development in China.更多还原
