数字化能否成为中国经济高质量发展的“新引擎”
Can Digitalization Become a “New Engine” for China’s High-Quality Development

基于中国2013年到2020年间省市级面板数据，运用动态面板模型和分位数回归模型分析了数字化对中国经济高质量发展的影响。熵权法结果表明，中国各省市经济高质量发展水平与数字化水平虽然都呈现上升趋势，但是都发展不均衡，都存在显著差异，并呈现明显的梯度特征。基准回归结果表明，数字化显著促进了中国经济高质量发展。非线性分析结果进一步表明数字化不仅能够助推经济高质量发展，而且随着其不断发展，助推作用也随之增强。异质性分析表明，与其他地区相比，东中部地区表现出显著的数字化异质性，凸显了数字化在高质量发展中的差异性。机制分析表明，产业结构优化和技术创新效应在数字化影响经济高质量发展的进程中都起到中介作用。本文讨论了数字化与经济高质量发展的关系，并为提升高质量发展水平、实现经济可持续发展提供有益建议。
Based on provincial and municipal panel data in China from 2013 to 2020, this paper analyzes the impact of digitalization on China’s high-quality economic development by using a dynamic panel model and quantile regression model. The results of the entropy weight method show that although the high-quality economic development level and the digital level of various provinces and cities in China show an upward trend, they are all uneven, there are significant differences and obvious gra-dient characteristics. The benchmark regression results show that digitalization has significantly promoted the high-quality development of China’s economy. The nonlinear analysis results further show that digitalization can not only promote high-quality economic development, but also enhance its role as it continues to develop. The heterogeneity analysis shows that compared with other re-gions, the East and Central regions show significant digital heterogeneity, highlighting the differ-ences in high-quality development of digitalization. Mechanism analysis shows that industrial structure optimization and technological innovation effects play an intermediary role in the process of digitalization affecting high-quality economic development. This paper discusses the relationship between digitalization and high-quality economic development, and provides useful suggestions for improving the level of high-quality development and achieving sustainable economic development.
