超大城市数据跨域流通:形态、路径和技术框架OA

Cross-domain data circulation constitutes a core link in the construction of a national integrated data market,however,it is confronted with a series of challenges including complex business forms,intertwined technical pathways,and the absence of a unified framework.Furthermore,the prominent characteristics of megacities-such as decentralized data sources,data heterogeneity,and scenario coupling-impose greater challenges on cross-domain data circulation.To address these challenges,five business forms and seven technical pathways of cross-domain data circulation are systematically collated and summarized.On this basis,drawing on the distinct data characteristics of public and private domains,an innovative"federation-confederation"dual-layer architecture is proposed,which enables complex data circulation within the public domain,within the private domain,and between the two domains via a multi-agent collaboration mechanism.Finally,a"scenario matrix"for cross-domain data circulation is developed,with cross-domain federated training of medical data adopted as a case study for empirical analysis.
