数字经济、技术创新与经济高质量发展研究

Research on digital dconomy,technological innovation and high-quality economic development

通过对2011年至2020年中国30个地区(除西藏、港澳台)的面板数据集进行分析,运用空间杜宾模型和中介效应模型,探讨了数字经济对经济高质量发展的影响机理和空间异质性。计量结果表明:(1)数字经济对中国经济高质量发展有正向影响。(2)数字经济水平的提升对相邻地区的经济发展具有抑制作用。(3)数字经济在东部、中部和西部均对经济高质量发展具有显著的促进作用,且中部地区效果最明显。(4)中介效应模型的结果表明,数字经济可以通过技术创新来推动经济的高质量发展。综上所述,数字经济在促进经济高质量发展方面起到了积极作用。然而,我们也需要注意数字经济发展可能导致的区域差异和数字隔离问题,为此需要制定针对性的政策来推动经济的均衡发展。同时,技术创新在数字经济中的关键地位也需要得到重视,促进技术进步将有助于实现经济的高质量发展。

Based on the analysis of panel datasets from 30 regions in China(excluding Tibet,Hong Kong,Macao and Taiwan)from 2011 to 2020,and using the spatial Durbin model and the mediating effect model,the impact mecha-nism and spatial heterogeneity of the digital economy on high-quality economic development are discussed.The measurement results show that:(1)The digital economy has a positive impact on the high-quality development of China's economy.(2)The improvement of the level of digital economy has an inhibiting effect on the economic de-velopment of neighboring regions.(3)The digital economy has a significant role in promoting high-quality economic development in the eastern,central and western regions,and the effect is the most obvious in the central region.(4)The results of the mediating effect model show that the digital economy can promote the high-quality development of the economy through technological innovation.To sum up,the digital economy has played a positive role in pro-moting high-quality economic development.However,we also need to pay attention to the regional disparities and digital segregation that may result from the development of the digital economy,and to this end,we need to formu-late targeted policies to promote balanced economic development.At the same time,the key position of technological inno-vation in the digital economy also needs to be paid attention to,and promoting technological progress will help achieve high-quality economic development.
