科技和金融耦合协调度测度、空间差异与收敛性分析

Study on the Measurement,Spatial Variation and Convergence of Coupling Coordination between Technology and Finance

科技和金融的融合协调发展对于区域创新和经济发展具有重要推动力。基于中国284个地级市的面板数据,使用熵值法与耦合协调度模型测算中国城市科技和金融耦合协调度,并使用Dagum基尼系数与空间收敛分析其空间差异与收敛性。研究发现,在样本期间内各城市科技和金融耦合协调度逐年上升,但总体水平依旧偏低;东部与西部地区间耦合协调度存在显著差异,从而造成总体空间差异扩大;耦合协调度的正向空间集聚特征逐年强化且增长稳定;总体与分地区的耦合协调度存在着显著的绝对β收敛特征,在控制影响因素后的条件β收敛分析中依旧成立,其中中部地区的收敛速度最快,其次是东部地区与西部地区。

The integrated and coordinated development of science and technology and finance is an important driving force for regional innovation and economic development.Based on the panel data of 284 prefecture-level cities in China,the entropy value method and the coupling coordination degree model are used to measure the coupling coordination degree of science and technology and finance in Chinese cities,and the spatial differences and convergence of the coupling coordination degree are analyzed using the Dagum Gini coefficient and spatial convergence.It is found that the coupling coordination degree of science and technology and finance in each city increases year by year during the sample period,but the overall level is still low;the significant difference in the coupling coordination degree between eastern and western regions is the main source of the expansion of the overall spatial difference;the positive spatial agglomeration characteristic of the coupling coordination degree strengthens year by year and grows steadily;there is a significant absolute β convergence characteristic of the overall and sub-regional coupling coordination degree,and it still holds true in the conditionalβconvergence analysis after controlling the influencing factors.The convergence speed of the central region is the fastest,followed by the eastern region and the western region.
