摘　　要：数字经济在全球经济增长中的地位不断攀升,并逐渐发展成为推动对外贸易重要的“加速器”和“稳定器”,而对外贸易与对外直接投资之间存在替代、互补和互动关系。为研究数字经济与对外直接投资的关系,选取2011—2021年31个省(区、市)面板数据,进行了基准回归分析、门槛效应分析、调节效应检验和异质性检验分析。结果表明:数字经济的发展显著正向促进对外直接投资水平的提升;数字经济对对外直接投资的影响具有门槛效应;技术创新水平在数字经济对对外直接投资水平的影响中发挥显著调节作用;数字经济正向影响东部地区的对外直接投资水平,但对中部和西部的对外直接投资水平影响不显著。The digital economy has been rising in the global economic growth and gradually developed into an important“gas pedal”and“stabilizer”to promote foreign trade.There are substitutions,complementarity and interactive relationships between foreign trade and foreign direct investment.To study the relationship between digital economy and foreign direct investment,this study selects the panel data of 31 provinces and cities from 2011 to 2021,and carries out benchmark regression analysis,threshold effect analysis,moderating effect test and heterogeneity test analysis.The results show that the development of digital economy significantly and positively promotes the level of OFDI;the impact of digital economy on OFDI has a threshold effect;the level of technological innovation is significant in the moderating effect of digital economy on the level of OFDI;the digital economy positively affects the OFDI level in the eastern regions,but its impact on the OFDI levels in the western and central regions is not significant.
