The emissions reduction of CO and air pollutants are the main task in China. The two have the same roots and they interact with each other. However, CO and air pollutants are quite different in space, so it is of great practical significance to explore the spatial differences of their synergy. As PM and O are more concerned at present, thus, this paper examined the decoupling of CO, PM and O from GDP in China's 296 cities using the latest available data from 2015 to 2016. And the spatial differences of synergy among CO, PM and O were quantitatively analyzed by using spatial autocorrelation analysis and geographically weighted regression model. The results showed that: (1) The cities achieving the three synergy emissions reduction were mainly in the southeast of China. (2) Only 26 cities had achieved the strong decoupling of CO, PM and O from GDP. (3) The synergy characteristics between CO and PM, CO and O were different. This paper put forward the policies according to the conclusions.
中国的主要任务是减少 CO 和空气污染物的排放。这两者有着共同的根源，并相互作用。然而，CO 和空气污染物在空间上有很大的不同，因此探索它们协同作用的空间差异具有重要的实际意义。由于目前人们更加关注 PM 和 O，因此，本文利用 2015 年至 2016 年的最新可用数据，检验了中国 296 个城市中 CO、PM 和 O 与 GDP 之间的脱钩情况。并通过空间自相关分析和地理加权回归模型，定量分析了 CO、PM 和 O 之间的协同空间差异。结果表明：（1）实现三协同减排的城市主要集中在中国东南部。（2）仅有 26 个城市实现了 CO、PM 和 O 与 GDP 的强脱钩。（3）CO 和 PM、CO 和 O 之间的协同特征不同。本文根据结论提出了政策建议。
