Abstract: As the core production factor of the digital economy, how can digital asset value (DAV) promote regional economic development has become an urgent academic issue to be explored. On the basis of reviewing relevant theories, this paper constructed a statistical regression model with regional economic growth as the explained variable, DAV as the explanatory variable,digital technology level as mediating variable, and data mobility as moderator?variable.We employed panel data from 28 provinces in mainland China from 2011 to 2020, excluding Xinjiang, Tibet, and Inner Mongolia since the data availability. Our results show: (1) DAV have a significant promoting effect on regional economic growth; (2) Digital technology level plays a mediating role between DAV and economic growth; (3) Data mobility can strengthen the positive impact of DAV on economic growth. (4) Further heterogeneity analysis illustrate that DAV have no significant promoting effect on regional economic growth within the central and western regions, and the key reason is the overall low level of digital technology in these regions.

摘要： 作为数字经济核心生产要素的数据要素，能否以及如何促进地区经济发展，已成为当前亟待探究的一个学术问题。在回顾相关理论的基础上，以数据资产价值代替数据要素规模，构建了以地区经济增长为被解释变量、地区数据资产价值为解释变量、数字技术水平为中介变量以及数据流动性为调节变量的回归模型，并利用我国大陆除新疆、西藏和内蒙古外的28个省份的2011-2020年十年间的面板数据进行实证研究。研究发现：（1）数据要素(资产)对地区经济增长具有显著的促进作用；（2）数字技术水平在地区数据要素(资产)与其经济增长之间起到中介作用；（3）数据流动性在地区数字技术水平和经济增长之间起到正向的调节作用，即数据流动性越高，数字技术水平对地区经济增长的促进作用越显著。（4）地区数据要素(资产)对经济增长的促进作用存在着异质性，中西部地区数据要素对地区经济增长仍无明显促进作用，其关键原因在于该地区的数字技术水平的整体低下。
