This paper took the 2007-2020 industrial integration policies as the research object and used grounded theory to code the policies. Specifically, the integration policies were analyzed quantitively from the perspective of the supply, environment and demand sides. Furthermore, a gigantic complex social network diagram was constructed to visualize the intern connection of policies by adopting the social network analysis approach. Besides, extensive in-depth quantitative research was carried in terms of network density and centrality. The finds indicated that the policy of industrial integration is more comprehensive, but the synergy between the policies is poor. Then, policies in the supply and environment sides account for a comparatively large proportion compared with these in the demand side, and some keywords are located at the edge of the social network.
