新基建与产业升级耦合协调发展的空间格局及影响因素

Spatial Pattern and Influencing Factors of Coupling and Coordinated Development of New Infrastructure and Industrial Upgrading

新基建已成为新时期产业转型升级与经济高质量发展的重要载体。为洞察我国新基建与产业升级耦合协调发展的空间格局及影响因素,构建新基建发展水平的综合评价指标,利用2013~2020年的省级面板数据,运用TOPSIS-熵值法和耦合协调模型测度新基建与产业升级的耦合协调度,继而使用ArcGIS18.0刻画其时空演化格局,并利用空间计量模型揭示其影响因素。结果发现:(1)我国新基建及其三大子系统(信息基建、融合基建和创新基建)发展水平逐年攀升;(2)我国新基建发展水平存在较大的空间异质性,东部高于全国平均水平,西部和东北相对滞后;(3)全国各省新基建与产业升级耦合协调度从2013到2020年总体提升幅度较大,但其与产业合理化的耦合协调度整体高于其与产业高级化的耦合协调度;(4)新基建与产业升级耦合协调度受到经济发展、城市规模、环境污染等多种因素的影响。对我国新基建与产业升级耦合协调演化特征及影响因素进行研判,期望为我国新基建与产业升级交互发展提供决策参考。

New infrastructure has become an important carrier of industrial transformation and upgrading and high-quality economic development in the new era.In order to understand the spatial pattern and influencing factors of the coupling and coordinated development of China’s new infrastructure and industrial upgrading,this paper first constructs a comprehensive evaluation index of the development level of new infrastructure.Secondly,using the provincial panel data from 2013 to 2020,it uses TOPSIS entropy method and coupling coordination model to measure the coupling coordinative degree between new infrastructure and industrial upgrade.Then,it uses ArcGIS18.0 depicts its spatio-temporal evolution pattern,and reveal its influencing factors by using spatial econometric model.The results show that:(1)the development level of China’s new infrastructure and its three subsystems(information infrastructure,integrated infrastructure and innovative economy)is rising year by year.(2)There is great spatial heterogeneity in the development level of China’s new infrastructure.The East is higher than the national average level,and the West and northeast are relatively lagging behind.(3)From 2013 to 2020,the coupling coordinative degree between new infrastructure and industrial upgrade in all provinces in China has increased significantly,but its coupling coordination degree with industrial rationalization is higher than that with industrial intensify.(4)The coupling and coordination degree of new infrastructure and industrial upgrading is affected by many factors,such as economic development,urban scale,environmental pollution and so on.This paper studies and judges the coupling and coordinated evolution characteristics and influencing factors of China’s new infrastructure and industrial upgrading,hoping to provide decision-making reference for the interactive development of China’s new infrastructure and industrial upgrading.
