Abstract: The integrated development of Chengdu, Deyang, Meishan and Ziyang, as the focus of efforts to start the"first move" in Chengdu-Chongqing economic circle, plays an important role in accelerating the economic development of the four cities. This paper uses DEA model to measure and analyze the efficiency level of financial resources cooperation of the four cities from 2015 to 2019, and studies the level of financial collaborative development. The results show that: though a certain foundation for the financial coordinated development of the four cities exists, there are great differences in the spatial distribution of financial resources, the deepening and specialization of financial industry development, and the relative efficiency and super-efficiency of allocation. In particular, Chengdu has obvious leading advantages in all aspects, and the financial development of the other three places is unbalanced, and this imbalance is difficult to bridge in the short term, which will hinder the coordinated development of the four cities. In this regard, the financial coordinated development of the four cities needs to make multiple efforts in reform planning, financial management, financial market entities, financial infrastructure, financial service standards, financial ecological construction and other aspects, so as to form a joint force and effectively promote the coordinated development of finance.
