Finance is the core of modern economy，and The coordinated development of Beijing-Tianjin-Hebei financial cooperation is an important promoter of Beijing-Tianjin-Hebei cooperation. As an important growth pole in the economic development of the north of China，the regional economy of Beijing，Tianjin and Hebei is large in size and rich in resources，but the development of the region is seriously unbalanced. Correspondingly，the irrational distribution of financial resources，the coexistence of idle and scarce financial resources，the convergence of industrial structure，the greater than the cooperation of financial competition and the large gap between regional industrial development are the main problems that restrict the coordinated development of Beijing-Tianjin-Hebei regional finance. Promote the coordinated development of financial cooperation between Beijing and Tianjin，to break the administrative barriers，strengthen innovation，and further promote the three financial infrastructure，cooperation platform，cooperation mechanism and other construction.
