摘要
基于2013—2021年中国31个省(区、市)面板数据,运用熵值法和耦合协调度模型测算中国31个省(区、市)区域技术创新和数字贸易发展评价指标体系及二者的时空耦合协调特征。研究发现:a) 2013—2021年中国31个省(区、市)区域技术创新水平和数字贸易发展均呈上升趋势,但东部、西部、中部、东北部地区仍呈现出不同程度的差距。b)区域技术创新与数字贸易耦合协调度持续增强,耦合协调度等级都有不同程度的提升,但耦合协调度差异较大,整体呈“东南强,西北弱”的空间分布格局。c)区域技术创新与数字贸易耦合协调局部空间效应较为显著,从东南至西北地区呈现明显的梯度分异,“高—高”集聚、“高—低”集聚以及“低—高”集聚主要分布于长江上中游经济区与东南沿海经济区,“低—低”集聚分布于青藏高原和西北边疆地区。针对耦合协调现状,提出制定因地制宜的区域协调发展政策、加强区域协同、提高发达地区的辐射效应、培育“极化区域”等政策建议。
Based on the panel data of 31 provinces(autonomous regions and municipalities)in China from 2013 to 2021,the entropy method and coupling coordination degree model were used to measure the evaluation index system of technological innovation and digital trade development in 3l provinces(autonomous regions and municipalities)in China and the spatiotemporal coupling and coordination characteristics of them.Three conclusions were drawn.First,from 2013 to 2021,the level of technological innovation and digital trade development in 31 provinces(autonomous regions and municipalities)in China showed an upward trend,but there were still different degrees of disparities in the eastern,western,central,and northeastern regions.Second,the coupling coordination between regional technological innovation and digital trade continued to strengthen,moving from varying degrees of imbalance to the primary coordination stage.However,there were significant differences in coupling coordination,and the overall spatial distribution was"strong in the southeast and weak in the northwest".Third,the coupling and coordination of regional technological innovation and digital trade had significant local spatial effects,showing a significant gradient differentiation from southeast to northwest."High-high"clustering,"high-low"clustering,and"low-high"clustering were mainly distributed in the upper and middle reaches of the Yangtze River Economic Zone and the Southeast Coastal Economic Zone.The"low-low"clustering mode was distributed in the Qinghai Tibet Plateau and the northwest border region.In view of the current situation of coupling and coordination,some policy suggestions are put forward,such as formulating regional coordinated development policies according to local conditions,strengthening regional coordination,improving the radiation effect of developed regions,and cultivating"polarized regions".
