摘　　要：数字经济蓬勃发展对改善收入机会不平等有着重要意义。本文基于CFPS2014-CFPS2018微观调查数据,从“互联网使用”和“数字普惠金融指数”两个维度测度数字经济发展,并通过构建理论和实证模型多层次讨论数字经济发展对代际收入流动产生的影响及其机制。研究发现,数字经济发展显著促进代际收入流动,且这种影响具有明显的“门槛效应”特征。引入工具变量和其他替代性检验后,该结论仍具有可靠性。数字经济对代际收入流动促进作用对低收入家庭更显著。机制检验表明:数字经济通过社会资本、财富资本和借贷资本影响代际收入流动。政策制定应着眼于加强互联网基础设施建设工作,拓宽数字普惠金融服务边界,制定动态化、差异化的数字经济政策。The flourishing development of digital economy holds significant importance in improving income opportunity inequality.This study utilizes micro data from the CFPS2014-CFPS2018 surveys to measure the development of digital economy from the dimensions of“internet usage”and“digital inclusive finance index.”By constructing the theoretical and empirical models,the paper discusses the multi-level impact of digital economy development on intergenerational income mobility and its mechanisms.The findings indicate that digital economy development significantly promotes intergenerational income mobility,exhibiting distinct“threshold effect”characteristics.Even after introducing the instrumental variable and alternative test,the result remains robust.Specially,the positive impact of digital economy development on intergenerational income mobility is more pronounced for low-income families.Mechanism analysis demonstrates that social capital,wealth capital and debt capital act as mediators between digital economy development and intergenerational income mobility.Policymaking should focus on strengthening internet infrastructure,expanding the boundaries of digital inclusive financial services and formulating dynamic and differentiated policies for digital economy.
