In the contemporary dynamic and changing environment, technology becomes a key resource that leads the firm to compete successfully, and at the same time, technology transfer becomes a non-substitutable approach to acquire technology Because most technology transfer is now transacted through firm network, it bears great significance to study technology transfer on the ground of firm network Based on the questionnaires, we conduct a positive analysis of the factors (including transferor’s characteristic, recipient’s characteristic, the extent of communication, the nature of technology, the firm network structure and so on) influencing technology transfer performance based on firm network, so the mechanism and extent of each factor’s impact becomes clear At last, we bring forward some feasible means and countermeasures for firms to implement successful technology transfer
