摘要
基于2013—2019年中国省际面板数据,运用耦合度模型计算各省数字经济发展与经济增长质量耦合度,并采用空间杜宾模型分析其驱动因素,得出以下结论:(1)中国省际数字经济发展水平和经济增长质量均呈现由东部沿海向中西部内陆逐级递减的空间分布特征;(2)数字经济发展与经济增长质量耦合度呈匀速增长的趋势,耦合度较高的省市由东部沿海向内陆延伸,呈“T”型分布格局,我国大部分省市经济增长质量提升领先于数字经济发展;(3)数字经济发展与经济增长质量耦合度的主要驱动因素有人均GDP、固定资产投资、人力资本、技术水平、外商直接投资,且耦合度的影响因素存在异质性。政府可在数字技术研发、数字要素市场建设、产业数字化转型等方面采取有效措施,推动数字经济发展和提升经济增长质量。
Based on China's provincial panel data from 2013 to 2019,the coupling degree model is used to analyze coupling relationship between development of digital economy and quality of economic growth,and the Spatial Durbin model is used to analyze driving factors of the coupling degree.The conclusions are as follows:(1)The development level of digital economy and the quality of economic growth in China's provinces are gradually decreasing from the eastern coastal areas to the central and western inland areas.(2)The coupling degree shows a trend of uniform growth,and the provinces with higher coupling degree extend from the eastern coast to the inland,showing a“T”distribution pattern.The improvement of economic growth quality of most provinces in China is ahead of the development of digital economy,and digital economy is still the short board of coordinated development of the two.The development degree of inland provinces and cities is generally low,and some provinces have low quality of both digital economy development and economic growth.(3)The main influencing factors of the coupling degree per capita GDP,fixed asset investment,human capital,technological level and foreign direct investment,and the influencing factors of coupling degree have heterogeneity characteristics.The government should take more effective measures in digital technology research and development,digital factor market construction and industrial digital transformation,so as to promote the development of digital economy and the improvement of the quality of economic growth.
