Abstract:In recent years, public health issues have become one of the obstacles to the integration of the Beijing-TianjinHebei region. The large-scale outbreak of influenza A H1 N1 epidemic in the Beijing-Tianjin-Hebei region during 2009 and2013 resulted in the rapid spread of the epidemic because of the lack of effective control of the epidemic in a short period of time. Based on the analysis of the current situation of public health cooperation between the three provinces and municipalities of Beijing, Tianjin and Hebei, this paper believed that there were still lack of horizontal and joint mechanisms, imbalance of government functions, and sharing of government information in the process of joint prevention and control of public health in the three provinces of Beijing, Tianjin, and Hebei and inadequate monitoring of public opinion and lack of legal safeguards. In addition, the causes of the problems in the joint prevention and control of public health in the three provinces and cities of Jing-Jin-Ji-Zu were summarized. It is believed that the lack of awareness in the administrative division system and regional games and government cooperation is an obstacle to the joint prevention and control of public health in the three provinces and cities of Beijing, Tianjin and Hebei.
