摘　　要：国内需求增量是经济内循环的主要动力,能够为全国经济循环的良好运转提供重要支撑。数字化和智能化的发展使经济循环突破了本地化和实物化的限制,为经济循环注入新的特征。运用网络爬虫技术获取城际数字信息流数据,构建数字信息传输量、信息聚合能力和信息辐射能力3个要素刻画城际数字信息流,并结合微观个体、企业和城市3个层面的数据考察城际数字信息流对经济内循环动力的影响及传递机制。研究结果表明:一是增强城际数字信息流能够提升城市的经济内循环动力,其中,城市数字信息传输量对经济内循环动力的促进作用具有边际递增特征,而城市信息聚合能力和信息辐射能力的促进作用具有边际递减特征。二是城际数字信息流更密集、城市经济内循环动力更强和人均收入更高的城市通过城际数字信息流来促进城市经济内循环动力的作用更强,城际数字信息流的发展可能会加剧数字鸿沟现象。三是城际数字信息流通过人口移动效应增加居民消费,通过新建企业效应增加企业投资,通过技术进步效应延伸产业链和供应链,从而提升城市的经济内循环动力。The increase in domestic demand,as the main driving force of the internal circulation of the economy,can provide important support for the good operation of the national economic cycle.The development of digitalization and intelligence has enabled the economic cycle to break through the limitations of localization and materialization,and inject new characteristics into the economic cycle.This paper uses web crawler technology to obtain intercity digital information flow data,describes intercity digital information flow through three variables including digital information transmission volume,information aggregation capabilities and information radiation capabilities,and combines the data of micro individuals,enterprises and cities to investigate the impact and transmission mechanism of intercity digital information flow on the internal circulation power of the economy.The conclusions of this paper are as follows.First,enhancing the intercity digital information flow can enhance the economic internal circulation power of the city,in which the promotion effect of urban digital information transmission on the economic internal circulation power has the characteristics of marginal increase,while the promotion effect of urban information aggregation capabilities and information radiation capabilities has the characteristics of marginal decline.Second,cities with denser intercity digital information flows,stronger urban economic internal circulation power and higher per capita income play a stronger role in promoting the internal circulation of urban economy through intercity digital information flow,and the development of intercity digital information flow may exacerbate the phenomenon of digital divide.Third,the intercity digital information flow increases residents’consumption through the population movement effect,increases enterprise investment through the effect of new ventures,and extends the industrial chain and supply chain through the effect of technological progress,so as to enhance the city’s economic i
