In particular the internet information to obtain and dissemination plays important role on the purchase decisions of consumers. Therefore, the study of the influence of information network to the purchase decision is a worthy topic of emerging research. This article will apply information network theory to research the impact mechanism of networking groups on real estate individual purchase behavior and housing market.The theme of the research is the impact of network information on house buying decisions.
