数字经济与实体经济的耦合协调及对经济增长的空间效应

Coupling Coordination of Digital Economy and Real Economy and Its Spatial Effects on Economic Growth

推动数字经济与实体经济融合发展是促进经济高质量发展的重要路径。通过分析数字经济与实体经济耦合协调机制,利用2011—2019年我国31个省份的面板数据,测算数字经济与实体经济的耦合协调度,研究其对我国经济增长的空间效应。研究发现,数字经济与实体经济的耦合协调度呈现出自东向西依次递减的分布格局,且具有明显的空间集聚特征。从地区层面上看,数字经济与实体经济耦合协调能显著促进经济增长,这种促进作用在中西部地区表现最为明显,同时它会通过发挥溢出效应来抑制邻近地区经济增长,且其溢出效应存在区域异质性:东部地区溢出效应为负,中部地区溢出效应为正,而西部地区溢出效应并不显著。此外,从实体经济的不同方面来看,数字经济与工业、建筑业、邮电运输业耦合协调能显著促进本地经济增长,同时存在负向溢出效应,而数学经济与批发业耦合协调仅对本地经济增长起促进作用,与住宿业耦合协调仅存在负向溢出效应。

Promoting the integrated development of digital and real economy is an important path for high-quality economic development.By constructing a coupling coordination mechanism between digital and real economy,using the panel data of 31 provinces in China from 2011 to 2019 to measure the coupling coordination,and its spatial effect on economic growth is studied.The study found that the coupling coordination of real and digital economy shows a distribution pattern that decreases sequentially from east to west and has obvious spatial agglomeration characteristics.From the regional perspective,deepening the integration of digital and real economy promotes economic significantly,which is mainly reflected in the central and the western.At the same time,it suppress the economic growth of surrounding areas by exerting its spillover effect,and there is a regional heterogeneity in the spillover effects,with negative spillover effects in the east,and positive spillover effects in the central,while the spillover effects in the western regions are not significant.In addition,from the perspective of different levels of real economy,the coupling coordination of digital economy and the industry,the construction industry,the post and telecommunications transportation industry promotes the growth of local economic significantly,and have negative spillover effects to other regions,while the coupling coordination of digital economy and the wholesale industry only promotes the growth of local economic,while the coupling coordination of digital economy and the accommodation industry only has a negative spillover effect.
