By following an empirical approach, this study proves that joint regional air pollution control (JRAPC) in the Beijing-Tianjin-Hebei region will save the expense on air pollution control compared with a locally-based pollution control strategy. The evidences below were found. (A) Local pollutant concentration in some of the cities is significantly affected by emissions from their surrounding areas. (B) There is heterogeneity in the marginal pollutant concentration reduction cost among various districts as a result of the cities' varying contribution of unit emission reduction to the pollutant concentration reduction, and their diverse unit cost of emission reduction brought about by their different industry composition. The results imply that the cost-efficiency of air pollution control will be improved in China if the conventional locally based regime of air pollution control can shift to a regionally based one.
本研究采用经验方法证明，京津冀地区的联合区域空气污染控制（JRAPC）将比基于本地的污染控制策略节省空气污染控制费用。以下是发现的证据。（A）一些城市的本地污染物浓度明显受到其周边地区排放的影响。（B）由于各地区单位减排对污染物浓度减排的贡献不同，以及不同产业结构导致的单位减排成本不同，各地区边际污染物浓度减排成本存在异质性。这意味着，如果中国能够从传统的基于本地的空气污染控制模式转变为基于区域的模式，那么空气污染控制的成本效益将会提高。
