摘　　要：区域创新在引领我国迈向绿色低碳发展的道路上发挥着至关重要的作用。文章基于2010—2023年长三角地区41个地级市的面板数据,采用双重差分模型,深入探讨长三角G60科创走廊对碳排放效率的影响。研究发现:长三角G60科创走廊能显著提升碳排放效率,并通过了一系列稳健性检验;长三角G60科创走廊可以通过产业结构升级、绿色技术创新和公众环保意识增强三条路径促进碳排放效率的提升;在政府干预程度高、金融发展水平高和数字基础设施支持高的城市,长三角G60科创走廊对碳排放效率具有显著的促进作用;长三角G60科创走廊具有空间溢出效应,且对周边城市的影响效应远大于对本城市的影响效应。Regional innovation plays a crucial role in leading our country towards a path of green and low-carbon development.The article,based on the panel data from 41 prefecture-level cities in the Yangtze River Delta from 2010 to 2023,takes a deep dive into the impact of the Yangtze River Delta G60 Science and Technology Innovation Valley on the carbon emission efficiency using a difference-in-differences model.According to the research findings,the Yangtze River Delta G60 Science and Technology Innovation Valley can significantly improve carbon emission efficiency,and has passed a series of robustness tests.The Valley can advance the improvement of the carbon emission efficiency through industrial structure upgrade,green technology innovation and increased public awareness of environmental protection.In cities with high-level government intervention,high-level financial development,and strong digital infrastructure support,the Valley significantly boosts the carbon emission efficiency.Additionally,the Valley exhibits a spatial spillover effect,with a much greater impact on surrounding cities than on the city itself.
