长三角区域数字经济与科技创新耦合协调发展研究

Research on the Coupling and Coordinated Development of Digital Eeconomy and Scientific and Technological Innovation in the Yangtze River Delta Region

本文运用耦合协调模型和相对发展模型实证分析数字经济与科技创新的耦合协调状态和相对发展水平。研究发现:从时序发展来看,2013—2020年长三角数字经济发展指数、科技创新发展指数总体上呈稳步上升状态,耦合协调水平呈现出从低度迈向中度再进入高度的演变规律,实现了数字经济发展滞后向同步发展的转变;从空间发展来看,2018—2020年间三省一市陆续迈进高度协调阶段,2016年以后三省一市数字经济与科技创新相对发展状态相差较大,不同的相对发展状态相互作用对长三角两系统相对发展水平产生影响。

This article uses the coupling coordination model and relative development model to empirically analyze the coupling coordination status and relative development level of digital economy and technological innovation.Research has found that:(1)From the perspective of temporal development,the digital economy development index and technological innovation development index in the Yangtze River Delta from 2013 to 2020 showed a steady upward trend,and the coupling coordination level showed an evolution pattern from low to moderate and then to high,achieving a transition from lagging digital economy development to synchronous development.(2)From the perspective of spatial development,from 2018 to 2020,the three provinces and one city gradually entered a highly coordinated stage.After 2016,the relative development status of the digital economy and technological innovation in the three provinces and one city varied significantly,and the interaction of different relative development states had an impact on the relative development level of the two systems in the Yangtze River Delta.
