摘　　要：基于2011—2019年中国省级面板数据,构建数字经济发展评价体系,并运用双向固定效应模型探究数字经济对地区出口产品质量升级的影响。研究结果表明:数字经济显著促进出口产品质量的升级,且存在区域异质性,表现为东、中部地区出口产品质量升级从数字经济发展中获益更多,西部未获得显著红利。进一步发现,数字经济在通过驱动区域创新提升出口产品质量过程中存在显著的创新主体异质性,作用强度表现为“企业>高校>科研机构”。最后,借助门限模型研究发现,数字经济对出口产品质量升级存在非线性影响,即数字经济对数字化程度较高的地区促进作用更强,存在后发劣势。Based on the provincial panel data of China from 2011 to 2019,this paper constructed the evaluation system of digital economy development,and used the two-way fixed effect model to explore the impact of digital economy on regional export product quality upgrading.The results showed that digital economy significantly promoted the upgrading of export product quality,and there was regional heterogeneity,indicating that the upgrading of it in the eastern and central regions benefited more from the development of digital economy,while the western region did not receive significant dividends.Furthermore,it was found that digital economy has significant innovation subject heterogeneity in the process of driving regional innovation to improve export product quality,and the effect intensity of enterprises was greater than universities,and that of universities was greater than scientific research institutions.Finally,with the help of the threshold model,it was found that the digital economy had a non-linear impact on the quality upgrading of export products,e.g.,the digital economy had a stronger promotion effect on regions with high digitization.A latter inferiority did exist.
