Low-carbon city (LCC) pilot is a strategic policy to deal with global climate change and energy poverty. Using the city-level data from 2006 to 2019, this paper applies a multiple difference-in-difference (DID) analysis to explore the impact of LCC policy on urban green total factor energy efficiency(GTFEE) and its potential mechanism. The results show that the LCC pilot policy can significantly improve urban GTFEE, and the finding remains robust with various tests. Secondly, we shed light on the mechanism of the LCC policy and explore the possible channels through green innovation and structural upgrading to improve the urban GTFEE. Third, the policy effect is affected by different levels of urban economic development, urban development scale, and urban development types. In cities with higher levels of economic development, super-large resource-based cities, the pilot policy has a more significant improvement effect on GTFEE. On the other hand, in the less developed regions, pilot policies will hinder the improvement of GTFEE.
低碳城市试点是应对全球气候变化和能源贫困的一项战略政策。本文利用 2006 年至 2019 年的城市层面数据，采用多倍差分法（DID）分析来探讨低碳城市试点政策对城市绿色全要素能源效率（GTFEE）的影响及其潜在机制。结果表明，低碳城市试点政策能够显著提高城市 GTFEE，且在各种检验下结果仍然稳健。其次，我们揭示了低碳城市政策的作用机制，并通过绿色创新和结构升级来探讨可能的渠道，以提高城市 GTFEE。第三，政策效果受到城市经济发展水平、城市发展规模和城市发展类型等因素的影响。在经济发展水平较高的城市、特大型资源型城市中，试点政策对 GTFEE 的改善效果更为显著。另一方面，在欠发达地区，试点政策会阻碍 GTFEE 的提高。
