数字金融与区域经济发展的耦合协调性测度及其动态演进

Measurement of the Coupling Coordination between Digital Finance and Regional Economic Development Level and its Dynamic Evolution

以中国八大综合经济区为例,运用耦合协调度模型分析数字金融对区域经济发展的耦合协调关系,并基于Dagum基尼系数与Kernel核密度揭示数字金融与区域经济发展之间协调关系的地区差异及动态演进规律。结果表明:八大综合经济区的经济发展水平总体呈现稳定增长态势,具有“东高西低”阶梯形的异质性和阶段性特征;数字金融与区域经济发展之间协调发展水平逐年提升,八大综合经济区普遍由失调阶段跨入协调阶段;数字金融与区域经济发展之间协调关系存在明显的地区差异,沿海经济区的协调水平明显高于内陆经济区,但地区间协调程度的差距呈现逐渐缩小的演进态势。

This study,using China's eight major comprehensive economic zones as a case study,employs a coupling coordination model to analyze the coupling coordination relationship between digital finance and regional economic development and reveals the regional differences and dynamic evolution patterns of the coordination relationship between digital finance and regional economic development based on the Dagum Gini coefficient and Kernel density.The results indicate that the overall economic development level of the eight comprehensive economic zones shows a stable growth trend,characterized by heterogeneity and periodic features with"higher in the east and lower in the west."The coordination development level between digital finance and regional economic development has increased year by year,and the eight comprehensive economic zones have generally transitioned from a state of imbalance to a coordinated stage.There are significant regional differences in the coordination relationship between digital finance and regional economic development,with coastal economic zones showing a significantly higher coordination level than inland economic zones;However,the regional gap in coordination degree tends to gradually narrow.
