The transformation of public consumption patterns has become a burning question, but there are few studies on public consumption patterns. Therefore, evaluating the impact of Information consumption city (ICC) policy on carbon emission efficiency holds significant implications. This study settles on 104 pilot cities in China from 2006 to 2020 to assess the impact and the response mechanism of ICC policy on carbon emission efficiency through the time-vary Difference-in-Difference (DID) model. The result shows that: (1) ICC policy significantly promotes the local carbon emission efficiency, which remains robust after a battery of sensitivity tests. (2) It improves carbon emission efficiency through production factors agglomeration effect, industrial structural changing effect, innovation promotion effect, and environmental attention effect; (3) The direct impact of ICC policy on carbon emission efficiency varies across regions with different information consumption and carbon emission base. (4) ICC can improve carbon emission efficiency through the joint implementation of smart city (SC), new urbanization (NU), ecological civilization city construction (EC), Belt and Road Initiative (BR), Broadband China (BC), low-carbon city pilot policy (LCC), and air quality standards (AQS) policy.
公众消费模式的转变已成为一个热点问题，但关于公众消费模式的研究却很少。因此，评估信息消费城市（ICC）政策对碳排放效率的影响具有重要意义。本研究选取了 2006 年至 2020 年的 104 个试点城市，通过时变双重差分（DID）模型评估 ICC 政策对碳排放效率的影响及其响应机制。结果表明：（1）ICC 政策显著促进了当地的碳排放效率，在一系列敏感性测试后仍然稳健。（2）它通过生产要素集聚效应、产业结构变化效应、创新促进效应和环境关注效应来提高碳排放效率；（3）ICC 政策对碳排放效率的直接影响因信息消费和碳排放基础不同的地区而异。（4）ICC 可以通过智慧城市（SC）、新型城镇化（NU）、生态文明城市建设（EC）、“一带一路”倡议（BR）、宽带中国（BC）、低碳城市试点政策（LCC）和空气质量标准（AQS）政策的联合实施来提高碳排放效率。
