Abstract：Based on the network perspective of regional multi-dimensional networks， the theoretical analysis framework of multi-dimensional cyberspace structure was established， and the multi-dimensional cyberspace structure， correlation characteristics and influencing factors of China's five major urban agglomerations were deeply studied. The results are shown as follows. 1) In terms of the network spatial structure， the multi-dimensional network of the five major urban agglomerations has obvious polar core characteristics and relatively significant hierarchical structure， with the network connection strength presenting a clear geographical attenuation law. 2) In terms of the overall network structure， the urban multi-dimensional network exhibits a multi thread， multi city and cross regional network distribution pattern， with significant “local area network” and small world characteristics. The stability and superposition effect of network connections need to be strengthened. 3) In terms of network centrality， the outward degree centrality of information contact network of the five urban agglomerations 〉 high-speed rail links 〉 Science and technology links 〉 capital links， and the inward degree of high-speed rail links 〉 Science and technology links 〉 capital links 〉 information links. 4) In terms of network similarity， the overrall multidimensional networks of the five major urban agglomerations show significantpositive correlation， and the correlation strength between different urban agglomerations and different dimensional networks has certain differences. 5) In terms of influencing factors， the multi-dimensional networks of the five major urban agglomerations are affected by geographical space， economic differences， institutional differences and cognitive differences to varying degrees. The significance and role of influencing factors show considerable regional heterogeneity.
