“双循环”视角下中国八大综合经济区金融资源配置效率分布动态、空间差异及收敛性研究

The Efficiency of Financial Resources Allocation of Eight Comprehensive Economic Zones in China from the Perspective of“Double Cycle”Study on Spatial Difference and Convergence

矫正金融资源失衡错配,促进构建国内经济大循环的前提是掌握金融资源配置效率的空间异质性。运用超密度DEA模型、Kernel密度估计、Dagum基尼系数及分解法、σ收敛和β收敛研究中国八大综合经济区2007—2018年金融资源配置效率水平、历史演进、空间差异和收敛性。研究发现:2007年以来全国及八大综合经济区金融资源配置效率均呈波动下降趋势,其中北方各经济区金融资源配置效率水平最低,下降趋势最大;八大综合经济区金融资源配置效率差异空间异质性特征突出,空间分布趋于发散,差异不断扩大,差异来源主要是区域间差异;全国、东北经济区、黄河中游经济区与西北经济区金融资源配置效率不存在σ收敛,差异趋于扩大。东部沿海经济区存在σ收敛,差异趋于缩小;全国、北部沿海经济区、东部沿海经济区、南部沿海经济区、黄河中游经济区、长江中游经济区、西南经济区与西北经济区存在显著的绝对β收敛和条件β收敛,金融资源配置效率将收敛至各自的稳态水平,东北经济区存在不显著的绝对β收敛和条件β收敛。不同经济区收敛的影响因素各不相同,在制定政策时一要转变思想观念,树立金融资源配置效率的质量观;二要重视金融资源配置效率的差异问题;三要促进金融资源跨地域合理流动,打通金融资源流动堵点,重视金融资源配置的空间合作;四要立足于不同经济区的经济社会特征,具体问题具体分析,多策并举,因地制宜。研究结论对于从区域层面了解金融资源配置效率面貌,精准施策促进金融资源配置效率从量到质转变,推进区域协调发展战略,促进要素流通,加快构建“双循环”新发展格局,具有积极的现实意义。

The premise of correcting the imbalance and mismatch of financial resources and promoting the construction of domestic economic cycle is to grasp the spatial heterogeneity of financial resource allocation efficiency.Using superdensity DEA model,kernel density estimation,Dagum Gini coefficient and decomposition methodσConvergence andβConvergence studies the efficiency level,historical evolution,spatial difference and convergence of financial resource allocation in China’s eight comprehensive economic zones from 2007 to 2018.It is found that the efficiency of financial resource allocation in China and the eight comprehensive economic zones has fluctuated and decreased since 2007,among which the level of financial resource allocation efficiency in the northern economic zones is the lowest and the downward trend is the largest;The spatial heterogeneity of the efficiency difference of financial resource allocation in the eight comprehensive economic zones is prominent,the spatial distribution tends to diverge,and the difference continues to expand.The source of the difference is mainly inter regional differences;The efficiency of financial resource allocation does not exist in the whole country,the Northeast Economic Zone,the middle reaches of the Yellow River Economic Zone and the Northwest Economic ZoneσConvergence,the difference tends to expand.Existence of the eastern coastal economic zoneσConvergence,the difference tends to narrow;There are significant absolute differences in China,the northern coastal economic zone,the eastern coastal economic zone,the southern coastal economic zone,the middle reaches of the Yellow River Economic Zone,the middle reaches of the Yangtze River Economic Zone,the southwest economic zone and the Northwest Economic ZoneβConvergence and conditionsβConvergence,the efficiency of financial resource allocation will converge to their respective steady state,and there is no significant absolute difference in the Northeast Economic ZoneβConvergence and conditionsβConvergence.The influencing factors of convergence in different economic zones are different.When formulating policies,we should change our ideas,establish the quality concept of financial resource allocation efficiency,and promote the allocation of financial resources to play a greater role in expanding domestic consumption and promoting the upgrading of industrial structure.Therefore,pay attention to the differences in the efficiency of financial resource allocation.Promote the rational flow of financial resources across regions,open up the blocking points of financial resources flow,and pay attention to the spatial cooperation in the allocation of financial resources.Measures should be taken accurately according to local conditions,and specific problems should be analyzed.The above conclusions are of great significance for understanding the efficiency of financial resource allocation from the regional level,accurately implementing policies,promoting the transformation of financial resource allocation efficiency from quantity to quality,promoting regional coordinated development strategy,promoting factor circulation,and accelerating the construction of a“double cycle”new development pattern.
