数字经济发展、政府介入与城市经济韧性

Development of digital economy,government intervention,and urban economic resilience

“十三五”以来,数字经济正在重塑区域经济格局,城市间数字联系日益紧密。利用2011-2021年全国277个地级及以上城市面板数据,基于产业视角从理论和实证方面检验数字经济对城市经济韧性的影响机制。研究发现:第一,数字经济发展会增强城市经济韧性,并放大冲击时的城市经济韧性,但其发展趋势为倒“U”型,下降原因是各主体处理效率提升下政府缺位引发的市场无序;第二,政府财政会拓宽数字经济影响渠道,但需通过市场机制及政府职能转变来实现;第三,数字经济加速中心城市经济韧性外溢,并且其在全国层面上存在中心-外围格局,要素虹吸会减弱经济韧性;第四,城市群层面则会促进规模相近的邻近城市经济韧性增长,并基于城市群行政结构产生异质性。研究结论从产业发展的角度分别对市政府、城市、城市群、区域间加强数字建设,强化城市经济韧性提供了政策参考。

Since the 13th Five-Year Plan,the digital economy has been reshaping the regional economic pattern,and the digital connection between cities has become increasingly close.Based on the panel data of 277 cities at the prefecture level and above in 2011-2021,this paper tests the effective impact mechanism of digital economy on the resilience of urban economy from the theoretical and empirical perspective of industry.The study found that:first,the development of the digital economy will enhance the resilience of urban economies and amplify the resilience of urban economies at the time of impact.However,the development trend is inverted"U"type,and the decline is the market disorder caused by the second,the government finance will broaden the influence channels of digital economy,but the transformation should be realized through the market mechanism and the transformation of government functions;third,the digital economy accelerates the economic resilience spillover of central cities,and the central-peripheral pattern at the national level will weaken the economic resilience;fourth,the urban agglomeration level will promote the economic resilience growth of neighboring cities with similar scale,and produce heterogeneity based on the administrative structure of urban agglomeration.From the perspective of industrial development,the conclusion provide policy reference for the municipal government,cities,urban clusters and regions to strengthen digital construction and strengthen the resilience of urban economy.
