摘要
文章基于城市经济韧性的科学测度,利用中国2005-2019年260个地级及以上城市的面板数据,从理论与实证两个方面检验了数字经济对市域经济韧性的影响效应及其作用机制。研究发现:①数字经济发展显著促进了中国市域经济韧性的提升,这一结论在系列稳健性检验后仍然成立。②机制检验表明,数字经济发展通过激发创业活跃度和创新活跃度两大机制最终促进市域经济韧性提升。③空间效应检验表明,数字经济对经济韧性提升存在正向溢出效应。④异质性分析发现,相对于中西部城市及外围城市而言,东部城市及中心城市数字经济发展对市域经济韧性的促进效应更强。文章具有重要的政策启示含义:加大数字经济发展力度,促进数字经济与实体经济深度融合,充分发挥数字经济促进“大众创业、万众创新”的作用,是提升中国市域经济韧性的重要途径。
Based on the panel data of 260 cities at prefecture level and above in China from 2005 to 2019,this paper examines the impact and mechanism of digital economy on urban economic resilience from both theoretical and empirical perspectives.It is found that:1)The development of digital economy has significantly improved the resilience of urban economy,and this conclusion still holds after a series of robustness tests.2)The mechanism test shows that stimulating entrepreneurial activity and innovation activity is the way of digital economy to promote the urban economic resilience.3)The spatial spillover effect test shows that the development of digital economy has a positive impact on the economic resilience of surrounding cities.4)According to the heterogeneity analysis,compared with central and western cities and peripheral cities,the digital economy development in eastern cities and central cities has a stronger promoting effect on the urban economic resilience.This study has important policy implications:strengthening the development of digital economy,promoting the deep integration of digital economy and real economy,and giving full play to the role of digital economy in promoting"mass entrepreneurship and innovation",which is an important way to enhance the resilience of China’s urban economy.
