Convergence Measurement and Convergence Mechanism Test of China's Financial Development
Financial development has played an important leading role in the economic growth of the economy.It has reached a consensus in the academic community.The imbalance of regional financial development is one of the factors that restrict the coordinated development of China's regions.The financial convergence hypothesis refers to the process in which the financial development level of low-level economies catches up with and draws close to high-level economies in the long run,that is,the process in which the financial development gap of economies gradually narrows to zero.It provides a complete analysis paradigm for the study of development gap,which can directly show the degree of narrowing the gap between economies,and can give a reasonable explana-tion for the causes of inter-regional gap.It is of great significance to narrow the gap of regional financial develop-ment for coordinating the balanced development of regional economy.Based on the convergence hypothesis,this paper identifies the convergence of financial development at the overall,regional and provincial levels in China,and further explores the influencing factors of China's financial convergence process,so as to provide ideas for explaining the imbalance of regional financial development in China.Firstly,in order to comprehensively measure the level of financial development in China,this paper selects multiple indicators at the three levels of banking,securities and insurance and uses the time series principal com-ponent analysis(GPCA)to construct a comprehensive evaluation standard.On this basis,this paper uses the nonlinear time-varying factor model to test the convergence of financial development at the overall,regional and provincial levels in China.The model breaks through the limitations of the homogeneity hypothesis of the tradi-tional identification method,and can accurately identify the phenomenon of short-term divergence and long-term convergence,and can realize the endogenous division of the convergence group.Further,this paper identifies the existing financial convergence groups in China through the convergence endogenous recognition algorithm,and analyzes the distribution of convergence groups and the change of convergence path.The results show that,first,under the premise of allowing the existence of heterogeneous convergence tran-sition path,China's financial development does not have the characteristics of national convergence,and the four major economic regions of the east,middle,west and northeast also show the characteristics of dispersion.Secondly,this paper further identifies four financial convergence groups endogenously,indicating that China's financial development converges to four different steady-state levels.Thirdly,the distribution of convergence groups presents a pyramid distribution pattern of"fewer members of high-level groups and more members of low-level groups",and there is a financial polarization phenomenon of"developed in the east,underdeveloped in the middle,west and northeast".However,with the evolution process,the gap between groups has gradually narrowed.Based on this,this paper argues that the convergence group should adopt differentiated development strategies according to local conditions,and the group should build a development mechanism in which competi-tion and cooperation coexist,so as to accelerate the speed of financial convergence and promote the coordinated development of financial levels in various regions.
