摘要
文章基于2013—2019年我国30个省份的面板数据,运用空间计量模型探究了数字经济驱动经济高质量发展的影响效应及时空差异。研究发现:数字经济发展指数稳步提升,但区域间差异较大,区域不平衡问题凸显。数字经济对经济高质量发展具有显著的空间集聚与溢出效应,但其边际效应趋于弱化。分维度来看,相比于数字基础设施和产业数字化,数字产业化对经济高质量发展具有更显著的空间集聚与溢出作用。分区域来看,东北和西部地区的数字基础设施、中部地区与东部地区南方省份的产业数字化、东部地区北方省份和东北与西部地区的数字产业化对经济高质量发展的正向作用明显大于其他地区。
Based on the panel data of 30 provinces in China from 2013 to 2019,this paper uses a spatial econometric model to explore the impact of digital economy driving high-quality economic development and its spatiotemporal differences.The results show that the development index of digital economy has increased steadily,but that the differences between regions are large,with prominent problem of regional imbalance.Digital economy has significant spatial agglomeration and spillover effect on high-quality economic development,but its marginal effect tends to weaken.From the perspective of dimension,compared with digital infrastructure and industrial digitalization,digital industrialization has more significant spatial agglomeration and spillover effect on economic quality.From a regional perspective,the positive effects of digital infrastructure in the northeast and western regions,industrial digitalization in the southern provinces of the central and eastern regions,and digital industrialization in the northern provinces of the eastern region and the northeast and western regions on high-quality economic development are significantly greater than those in other regions.
