摘要
中国广大欠发达地区城市正在寻求一系列方案措施来激发数字经济带来经济增长的红利效应。为探讨数字经济发展对欠发达地区城市经济高质量发展的赋能作用及影响机制,根据数字经济和经济高质量发展内涵构建城市层面的数字经济及经济高质量发展评价指标体系,在熵值法测算相关指数的基础上,采用双向固定效应模型对2012—2021年广西14个地市面板数据进行分析,同时用个体与时间双向固定模型检验科技创新因素的中介效应。实证结果表明:欠发达地区城市数字经济与经济高质量发展水平稳步上升,但存在发展不平衡、不充分问题;数字经济显著促进欠发达地区城市经济高质量发展,同时政府干预程度、产业结构水平、高等教育水平及城镇化率提升能有效促进欠发达地区城市经济高质量发展;科技创新在数字经济促进欠发达地区城市经济高质量发展过程中起重要中介作用。基于结论,提出实施差异化数字发展战略、推动传统产业数字化转型升级等推动欠发达地区城市经济高质量发展的政策建议。
Cities in underdeveloped areas are seeking various solutions to stimulate the dividend effect of digital economy on economic growth.To explore the empowering role and impact mechanism of the development of digital economy on the high-quality economic development of cities in underdeveloped regions,an indicator system for digital economy and high-quality economic development at the urban level is constructed based on the connotation of digital economy and high-quality economic development.Using the entropy method to calculate relevant indices,a two-way fixed effects model is applied to analyze panel data of 14 cities in Guangxi from 2012 to 2021.Additionally,an individual and time two-way fixed effects model is used to test the mediating effect of technological innovation.Empirical results indicate that digital economy and high-quality economic development of cities in underdeveloped areas is steadily increasing,but problems of imbalanced and insufficient development persist,and the digital economy significantly promotes the high-quality economic development.Besides,factors such as the degree of government intervention,industrial structure level,higher education,and rising urbanization rate can effectively enhance the highquality economic development of these cities.In addition,technological innovation plays an crucial intermediary role in the process of the digital economy advancing high-quality economic development of cities in underdeveloped areas.From these conclusions,policy suggestions are proposed,including implementing differentiation strategies,promoting the digital transformation and upgrading of traditional industries,and so on,to promote the high-quality economic development of cities in underdeveloped regions.
