摘　　要：中国式现代化愿景下制造业集聚成为实现中国经济提质增效发展的关键。基于2011—2020年30个省级面板数据,利用熵值法测度制造业集聚水平,并构建中介效应模型和空间杜宾模型,实证检验制造业集聚、技术进步对碳生产率的影响及作用机制。结果表明:制造业集聚会对碳生产率的提高产生倒U型的影响,且这种影响存在空间溢出效应;制造业集聚能够通过技术进步的中介效应对碳生产率提高产生正向影响。作用机制的实证分析结果显示,由于要素禀赋结构的差异,制造业集聚对碳生产率的影响在空间上呈现明显的异质性。东部地区制造业集聚对碳生产率具有正向促进作用;西部地区制造业集聚对碳生产率具有抑制作用。Under the vision of Chinese-style modernization,manufacturing agglomeration has become the key to improving the quality and efficiency of China's economy.Based on the data of 30 provincial panels from 2011 to 2020,the entropy method was used to measure the level of manufacturing agglomeration,and the mediation effect model and spatial Durbin model were constructed to empirically test the impact and functioning mechanism of manufacturing agglomeration and technological progress on carbon productivity.The results show that manufacturing agglomeration has an inverted U-shaped impact on the improvement of carbon productivity,and this effect has a spatial spillover effect.Manufacturing agglomeration can have a positive impact on the improvement of carbon productivity through the mediating effect of technological progress.The empirical analysis of the mechanism of action shows that the impact of manufacturing agglomeration on carbon productivity is spatially heterogeneous due to the difference in factor endowment structure.Manufacturing agglomeration in the eastern China has a positive effect on carbon productivity.Manufacturing agglomeration in the western China has an inhibitory effect on carbon productivity.
