摘　　要：数据要素作为推动经济高质量发展的新动能,在构建新发展格局中发挥着关键作用。基于2005—2019年中国283个城市的面板数据,将国家级大数据综合试验区的设立看作一项准自然实验,采用多期DID和PSM-DID方法,实证检验大数据试验区设立对城市经济增长质量的影响。研究结果如下:(1)大数据试验区设立能显著推动城市经济高质量发展,且该促进作用持续增强。(2)机制分析发现,大数据试验区设立主要通过激发创业活力、促进人力资本积累以及推动绿色技术创新等渠道提升城市经济增长质量。(3)异质性分析发现,大数据试验区设立对东部地区、较大规模和高等级城市经济高质量发展具有更强的驱动效果;城市创新水平、互联网发展水平和市场化水平越高,大数据试验区设立的经济增长质量效应越显著。(4)进一步研究发现,大数据试验区设立不但能推动本地经济高质量发展,而且对邻地经济增长也具有正向的空间溢出效应。As a new driving force for high-quality economic development,data elements play a key role in the construction of a new development pattern.Based on the panel data of 283 cities in China from 2005 to 2019,the establishment of national comprehensive big data pilot zone is regarded as a quasi-natural experiment,and the multi-stage DID and PSM-DID methods are used to empirically test the impact of the establishment of big data pilot zone on the quality of urban economic growth.The quality effect of data factors on economic growth is investigated from the aspects of urban location,urban scale,urban grade and urban characteristics.On this basis,the influence mechanism of entrepreneurial vitality,human capital and green technology innovation is analyzed as moderating variables.Finally,whether it has spatial spillover effect is discussed.The results show that:(1)On the whole,the establishment of big data pilot zone can significantly promote the high-quality development of urban economy,and the promotion effect is continuously enhanced.(2)Mechanism analysis shows that the establishment of big data pilot zone can improve the quality of urban economic growth mainly through stimulating entrepreneurial vitality,promoting human capital accumulation and promoting green technology innovation.(3)Heterogeneity analysis shows that the establishment of the big data pilot zone has a stronger driving effect on the high-quality economic development of the eastern region,large-scale and high-grade cities.Meanwhile,the higher the level of urban innovation,internet development and marketization,the more significant the quality effect of the establishment of the big data pilot zone on economic growth.(4)Further research shows that the establishment of big data pilot zone can not only promote the high-quality development of local economy,but also has a positive spatial spillover effect on neighboring areas.This study provides important policy implications for further mining the potential value of data elements and enabling high-quality dev
