Low-carbon city pilots (LCCP) is a key policy for realizing emission peak and carbon neutrality in China, using China's samples from 280 towns from 2006 to 2016. The article utilizes PSM-DID, mediated effects, and moderating effects approach for validating a CO reduction effect, mechanisms, and synergistic elements of LCCP. The regression outcomes suggest that (1) LCCP significantly decreases CO emissions levels and average annual carbon emissions in LCCP fall by 2.6 percent. (2) LCCP focus on reducing carbon emissions by increasing R&D investment, the efficiency of energy, and decreasing the high CO emissions industry. Among them, the reduction of the high carbon emission industry is mainly FDI, while the reduction of local industry is not obvious. (3) LCCP's carbon reduction effects suggest a reversed U-shape relationship with city size. Digitalization and marketization of LCCP are crucial to the carbon reduction effect. Carbon reduction and pollution reduction have a strong synergistic effect.
低碳城市试点（LCCP）是中国实现排放峰值和碳中和的关键政策，该文利用中国 2006 年至 2016 年 280 个城镇的样本，采用 PSM-DID、中介效应和调节效应方法，验证了 LCCP 的 CO 减排效应、机制和协同要素。回归结果表明：（1）LCCP 显著降低了 CO 排放水平，LCCP 内的平均年碳排放量减少了 2.6%。（2）LCCP 通过增加研发投入、能源效率和降低高 CO 排放产业来重点减少碳排放。其中，高碳排放产业的减少主要是通过 FDI，而地方产业的减少则不明显。（3）LCCP 的碳减排效应与城市规模呈倒 U 型关系。LCCP 的数字化和市场化对碳减排效应至关重要。碳减排与污染减排具有很强的协同效应。
