Beijing-Tianjin-Hebei is the center of economic development in northern China. However，the environmental problems in Beijing-Tianjin-Hebei have been prominent in recent years. This paper studies the impact of industrial structure，population changes，energy structure，and science and technology level on environmental pollution before and after the coordinated treatment of Beijing-Tianjin-Hebei environmental pollution，and analyzes the effectiveness of coordinated management of environmental pollution in Beijing-Tianjin-Hebei. At last，this paper proposes the relevant countermeasures to promote the coordinated treatment of environmental pollution in Beijing-Tianjin-Hebei. Since the Beijing-Tianjin-Hebei coordinated development strategy was put forward，Beijing-Tianjin-Hebei three cross-regional factories，the establishment of industrial parks，the degree of industrial integration is becoming deeper and deeper. But there are also problems such as unreasonable industrial structure，inconsistent environmental emission standards and systems，and unequal investment and return on pollution control. It is suggested to speed up the adjustment of regional industrial structure，unify standards and systems，and improve the mechanism of interest compensation.
