摘　　要：基于2004-2019年中国内地280个地级市面板数据,运用引力模型测度创新要素流动与数据要素流动环境指数,采用SBM-Undesirable模型测算城市绿色创新发展效率,使用空间杜宾模型分析创新要素流动对城市绿色创新发展的空间影响,并探究数据要素流动环境的空间调节效应。研究发现:创新要素流动仅通过改善绿色技术效率促进本地绿色创新发展,而对邻近地区绿色创新发展起抑制作用。在数据要素流动环境的调节作用下,从本地效应看,人才要素流动通过影响绿色技术效率和绿色技术进步促进城市绿色创新发展,呈“双轨驱动”特征;资本要素流动仅通过改善绿色技术效率提升城市绿色创新发展水平,呈“单轨驱动”特征。从空间溢出效应看,数据要素流动环境能合理调节人才和资本要素的空间流动,缓解创新要素的空间错配,进而对邻近地区绿色创新发展存在正向空间溢出效应。In the high-quality development stage of China’s economy,green innovation is the fundamental driving force for green growth and green welfare which are the ultimate goals of green innovation.Strategies of green sustainable development and innovative development are inevitable choices for China’s high-quality economic development.It is also a must to realize the domestic cycle to promote the free flow of innovation elements in the construction of a unified national market.In addition,a good sharing and circulation environment of data element can not only promote the effective flow of data elements and deeply tap the potential of data elements and fully release the dividends of data elements,but also guide the orderly flow and precise matching of innovative elements such as talents and capital.Then does innovation elements mobility promote urban green innovation development?What exactly is the role of the flow environment of data elements in the development of urban green innovation?An in-depth exploration of the above two issues provides an empirical reference for the formulation of policies related to the synergistic development of"innovation"and"green"in cities in the digital economy to fully explore the potential value of data elements and enable the development of urban green innovation.This study uses the panel data of 280 prefecture-level cities in China from 2004 to 2019,and employs the gravity model to measure the flow of innovation elements and the environment index of data-flow.Then it measures the development efficiency of urban green innovation by the SBM-undesirable model,and uses the spatial Durbin model to empirically analyze the spatial impact of the flow of innovation elements on the development of urban green innovation,and explore the mitigation effect of innovation element mismatch in the flow environment of data elements,as well as its spatial adjustment effect on the development of urban green innovation.The research finds that firstly,the flow of innovation elements only promotes the dev
