中国科技金融与产业结构转型升级耦合协调的时空演化研究

Spatial-temporal Evolution of the Coupling Coordination Between Sci-tech Finance and Industrial Structure Transformation and Upgrading in China

科技金融与产业结构转型升级的良性互动已成为实体经济高质量发展的关键支撑力。运用耦合协调度模型、Dagum基尼系数分解法和空间Kernel密度估计法考察科技金融与产业结构转型升级耦合协调的时空演化特征。研究发现:科技金融与产业结构转型升级耦合协调发展向优质阶段迈进的关键是提升产业结构转型升级水平;我国科技金融与产业结构转型升级耦合协调度空间差异的主要来源是超变密度和区域间差异;东部地区耦合协调度的空间均衡格局逐渐完善,中部、西部和东北地区耦合协调度分布均存在不同程度的多极化特征;在考虑空间因素和时间跨度的条件下,我国多数省份与相邻省份科技金融与产业结构转型升级耦合协调的空间关联作用得到显现。研究有助于推动科技金融与产业结构转型升级的耦合协调发展,为实现区域实体经济高质量协同发展提供科学合理的决策参考。

The benign interaction between sci-tech finance and the transformation and upgrading of the industrial structure has become a key supporting force for the high-quality development of the real e-conomy.The spatial-temporal evolution characteristics of the coupling coordination between sci-tech fi-nance and industrial structure transformation and upgrading are investigated by coupling coordination degree model,Dagum Gini coefficient decomposition and spatial Kernel density estimation.The research found that improving the level of industrial structure transformation and upgrading is the key to the coupling and coordination of sci-tech finance and industrial structure transformation and upgrading to a high-quality stage.The main sources of spatial dfferences of the coupling coordination degree between sci-tech fi-nance and industrial structure transformation and upgrading in China are super variable density and inter-regional differences.The spatial equilibrium pattern of coupling coordination degree in eastern China is gradually improved,and the distribution of coupling coordination degree in central,western and northeast China has different degrees of multi-polarization characteristics.Under the condition of considering spa-tial factors and time span,the spatial correlation effect of the coupling coordination of sci-tech finance and industrial structure transformation and upgrading in most provinces and their neighboring provinces in China has emerged.It is conducive to promoting the coupling coordinated development of sci-tech fi-nance and industrial structure transformation and upgrading,and provides scientific and reasonable deci-sion-making reference for realizing the high-quality coordinated development of the regional real econo-my.
