The invention discloses a virtual platform system based on user behavior data. The virtual platform system comprises a network server, a relational database server, a user management server, a virtual tool management server, a scene management server, a voice server, an image capturing server, a data collection server, a data analysis server, a message transmission server, a virtual scene client terminal, a user image capturing client terminal, a voice client terminal, a user management client terminal, a virtual tool client terminal and a behavior collection client terminal. The virtual platform system based on the user behavior data has the advantages that a collection system is that a user enters the virtual reality environment and acts, and meanwhile behavior data generated in the virtual reality environment of the user is captured; through the system, realistic user behavior can correspond to a virtual reality platform, the behavior data in the virtual reality environment of the user is captured, collected, finished and subjected to modeling analysis, and therefore collection and analysis based on mass data are achieved.
