This article analyzes the characteristics of Beijing’s financial operation in 2017，and believes that the growth rate of deposits and loans is generally stable. Among them，the growth rate of RMB deposits has dropped significantly，the growth rate of RMB loans has remained stable，the growth rate of foreign currency deposits has rebounded，foreign currency loans have continued to grow negatively，and direct financing has continued. The scale has dropped sharply，and loan interest rates and bond financing costs have generally risen. There has been an upside down between the two. It is necessary to pay attention to the “central-enterprise effect” of the transmission of monetary policy in Beijing，the potential risks and problems in the real estate market，the related risks in the “relearning” of the financial system，the adjustment of the benchmark interest rates of deposits and loans，and the adjustment of the monetary policy instruments’ operating interest rates，related influences and so on. It is suggested that monetary policy transmission channels and mechanisms should be further smoothed，and the stability of real estate financial control policies should be maintained and actively served in the construction of long-term control mechanisms. Various methods should be adopted to further increase the flexibility of interest rate policy adjustments and improve liquidity risk prevention and controlled mechanism.
