数字经济、技术创新与高质量发展

Digital Economy,Technological Innovation and High-quality Development

当前,数字经济作为一种新经济形态,正逐渐成为我国高质量发展的重要引擎。文章以2011—2020年我国31个省份的面板数据为样本,基于新发展理念视角,从创新、协调、绿色、开放、共享五个维度衡量高质量发展水平,通过构建有调节的中介效应模型对数字经济、技术创新与高质量发展之间的关系及作用机制进行实证检验。研究发现:(1)在全国层面,数字经济和技术创新均能对高质量发展产生显著的促进作用,且数字经济能够通过技术创新产生中介效应。(2)受到地区发展基础、发展阶段迥异等因素影响,数字经济促进高质量发展的影响存在地区异质性和维度异质性。其中,分地区来看,在东部和西部地区呈现显著正向激励作用,而在中部地区则呈现显著的抑制作用;分维度来看,创新、协调、绿色、共享均呈现显著的促进作用,而开放在现阶段的促进作用尚不显著。(3)有调节的中介效应检验结果显示,全要素生产率能够在数字经济促进技术创新与高质量发展的过程中起到正向调节作用。

At present,as a new economic form,digital economy is becoming an important engine for China to achieve high-quality development.Taking the panel data of 31 provinces from 2011 to 2020 as samples,and based on the perspective of new development concept,this paper measures the high-quality development level from the five dimensions of innovation,coordi-nation,greenness,openness and sharing,and then empirically tests the relationship and mechanism between digital economy,technological innovation and high-quality development by constructing a regulated intermediary effect model.The results are shown as the following:(1)At the national level,digital economy and technological innovation can significantly promote high-qual-ity development,and digital economy can produce intermediary effects through technological innovation.(2)Influenced by factors such as different regional development bases and stages,the impact of digital economy on high-quality development has regional heterogeneity and structural heterogeneity.Among them,the eastern and western regions show significant positive incentives,while the central region shows significant inhibition.In terms of structure,innovation,coordination,greenness and sharing have all been significantly promoted,while the role of openness is not significant at this stage.(3)It is found that TFP can play a positive regulatory effect in the process of digital economy promoting technological innovation and high-quality development.
