摘　　要：基于中国2013—2019年省际面板数据,选取数字经济基础设施建设、数字化产业、数字化应用以及数字化创新等四个方面共18项指标,采用熵值法进行赋权,计算中国30个省份数字经济发展情况综合得分,衡量中国不同省份数字经济的发展水平。然后从数字经济的直接传导机制与间接传导机制出发,构建空间杜宾模型,考察中国不同省份数字经济发展对区域GDP的促进作用及空间溢出效应。结果显示:各省份经济增长与数字经济的发展呈现空间集聚效应,数字经济的发展对GDP存在正向的外部效应,且作用明显,具有空间溢出效用。Based on Chinese inter provincial panel data from 2013 to 2019,18 indicators in four aspects of digital economy infrastructure construction,digital industry,digital application and digital innovation are selected.Weighted by entropy method,the comprehensive score of digital economy development of 30 provinces in China is calculated to measure the development level of digital economy in different provinces in China.Then,starting from the direct transmission mechanism and indirect transmission mechanism of digital economy,this paper constructs a spatial Dobbin model to investigate the promotion effect and spatial spillover effect of digital economy development on regional GDP in different provinces of China.The results demonstrate that the economic growth and digital economy development of each province show spatial agglomeration effect,and the development of digital economy has positive external effect on GDP,which has obvious effect and spatial spillover effect.
