Abstract:At present, the science popularisation in China includes two main subjects, which are popular science institutions and individuals. The popular science media mainly includes mobile social platform accounts, popular science APPs, and popular science websites. “Mobile internet +”science popularisation has the characteristics of multi-subjects, popular audiences, three-dimensional contents and variant dissemination channels. In order to realise the effective closed-loop integration between offline science popularisation activities and online science popularisation activities, this paper establishes the conceptual model of “mobile internet" + science popularisation integration model, which based on three principles: integration, extensiveness and effectiveness. Combined with the practice of Fintech science popularisation in Guangzhou, this paper analyses the specific implementation path of the “mobile Internet+” science popularisation integration model. This model can effectively increase the breadth of popular science information dissemination, deepen the depth of popular science information and enhance popular science efficiency.
