摘要：大气污染的治理不仅要考虑污染物排放量控制与污染损失减少的关系，还应该考虑污染物排放的时间和空间效应。本文首先从污染物排放和大气自然净化能力的平衡角度建立模型，描述了大气环境的污染和净化过程，揭示了大气环境资源的时空异质性、经济学概念及政策含义。然后从中国大气环境资源利用角度进行实证分析，以中国省会城市和50个样本城市的相关数据为例，发现大气环境资源时空异质性确实存在。最后提出有针对性的优化大气污染控制政策的方法和思路，包括污染物排放的空间转移策略和错峰排放机制。

Abstract: The problem of air pollution cannot be only considered as the relationship between pollutant discharge control and pollution loss reduction, but also consider the time and space effects of pollutant emission. This paper attempts to expound the economic concept, spatial and temporal heterogeneity, and policy implications of atmospheric environmental resources from the perspective of balance between pollutant discharge and air self-purification capacity by a simple model. In this model, air pollution process is described as pollute-self-purification process, namely describing the process of air pollution that is divided into two parts: pollution and purification. Then, this paper makes an empirical analysis from the perspective of China's atmospheric environmental resources utilization. Taking China's provincial capital cities and 50 sample cities as an example, it is found that the spatiotemporal heterogeneity of atmospheric environmental resources does exist. Finally, some policy recommendations are proposed, including the spatial transfer strategy of pollutant emission and the staggered peak emission mechanism.
