数实融合与经济高质量发展耦合协调的时空演进及差异分析

Spatio-temporal evolution and differential analysis of the coupling and coordination between data-reality integration and high-quality economic development

数实融合是中国共产党二十大报告的明确要求,对助推经济高质量发展具有重要作用。从基础融合、创新融合、应用融合、效益融合和生态融合5个维度构建中国数实融合发展评价指标体系,基于2010-2021年中国30个省区市的面板数据,对数实融合、经济高质量发展及二者的耦合协调水平进行测算,并运用核密度估计和Dagum基尼系数法对其时空演进与区域差异进行了研究。结果表明:各省耦合协调水平总体不断提升;在研究期内,耦合协调度较低的地区上升幅度较大,呈现追赶趋势,但增长速率逐步放缓。全国范围内,耦合协调水平呈先集聚后分散的趋势,虽差距逐步缩小,但已经出现多级分化特征;不同区域的耦合协调水平演进呈现不同趋势。数实融合与经济高质量发展的耦合协调区域差异有所缓解,主要差异来源于区域间差距。东部地区省份之间的耦合协调水平差距最大,与其他地区之间的耦合协调发展水平差距也最为显著。

Digital-real integration is explicitly mandated in the Twentieth National Congress report and plays a pivotal role in fostering high-quality economic development.This paper had established an evaluation index system for China′s digital-real integration development,encompassing five dimensions:basic integration,innovation integration,application integration,benefit integration,and ecological integration.Utilizing panel data from 30 provinces in China spanning the period 2010 to 2021,this paper measured digital-real integration,economic high-quality development,and the coupling and coordination level between the two.This paper studied the spatio-temporal evolution and regional differences using kernel density estimation and Dagum′s Gini coefficient method.The results indicated that the level of coupling coordination in all provinces had shown a general increase.During the study period,regions with lower levels of coupling coordination experienced a significant rise,demonstrating a catching-up trend,although the growth rate has gradually slowed down.Nationally,the coupling coordination level exhibited a pattern of initial agglomeration followed by dispersion.While the gap was narrowing,it was marked by multilevel differentiation,and the evolution of coupling coordination levels across regions also displayed diverse trends.Regional disparities in the coupling coordination of digital-real integration and high-quality economic development had eased,primarily stemming from inter-regional gaps.The largest gap in coupling coordination levels between provinces was observed in the eastern region,with the most significant disparity in coupling coordination development levels compared to other regions.
