摘　　要：在消费增长乏力、“双碳”目标日趋紧迫的背景下,信息消费如何赋能经济低碳转型以实现高质量发展是当前亟需解决的重要问题。文章以信息消费试点政策为准自然实验,基于中国2006-2021年城市面板数据,探究信息消费对城市碳生产率的影响机制及空间溢出效应。研究发现,信息消费试点政策显著提升了碳生产率,该结论在经过内生性问题处理以及一系列稳健性检验后依然成立。机制分析表明,信息消费试点政策通过推动生产性服务业专业化集聚、抑制生产性服务业多样化集聚以及促进绿色技术创新,进而提升碳生产率。此外,信息消费试点政策的碳生产率提升效应因城市区位、城市是否在城市群内、信息基础设施和数字普惠金融发展而异。进一步研究发现,信息消费试点政策对碳生产率的影响存在正向空间溢出效应,溢出边界为距离试点城市100-800公里。本文为如何通过促进信息消费实现经济增长与碳减排协同提供了理论支撑和经验证据。In the context of weak consumption growth and the increasingly urgent goal of"double carbon",how information consumption enables the low-carbon transformation of the economy to achieve high-quality development is an important issue that needs to be solved.This paper takes the information consumption pilot policy as a quasi-natural experiment,and explores the impact mechanism and the spatial spillover effect of information consumption on urban carbon productivity,based on the panel data of Chinese cities from 2006 to 2021.The study finds that the information consumption pilot policy significantly improves carbon productivity,and this conclusion holds true after the endogeneity problem treatment and a series of robustness tests.Mechanism analysis shows that the pilot policy of information consumption can promote carbon productivity by promoting specialized agglomeration of producer services,restraining diversified agglomeration of producer services and promoting green technology innovation.In addition,the carbon productivity enhancing effects of information consumption pilot policy vary depending on city location,whether the city is within urban agglomerations,information infrastructure and digital financial inclusion development.Further research shows that the impact of information consumption pilot policy on carbon productivity has a positive spatial spillover effect,and the spillover boundary is 100-80o km away from the pilot cities.This paper provides theoretical support and empirical evidence for how to achieve synergy between economic growth and carbon emission reduction by promoting information consumption.
