Abstract:In the highly turbulent transformation environment, how to ensure the smooth transition and transformation of new and old innovation (system) is an important issue that is concerned by business circles and theorists. From the perspective of the innovation stream, this paper selects 6 high-tech enterprises that are undergoing or have undergone innovation transformation as the research objects, adopts grounded theory research method to analyze these cases, and constructs the risk control mechanism of mainstream innovation and newstream innovation transformation. The results show that the transformation risk identification of mainstream innovation and newstream innovation transformation is an important reason for the two-streams risk control behavior, which mainly includes the variation risk identification of pattern, capability, and resource. The results also show that on the basis of identifying and evaluating the innovation transformation risk of the two-streams, enterprises follow the logic of “risk identification, risk assessment, risk control, risk governance effect”, and control the innovation variation risks of two-streams by carrying out structural convention updating, resource elastic governance and transitional learning, and ultimately facilitates newstream innovation performance improvement. The research conclusions can provide enlightenment for enterprises in the innovation transformation period, that is, to ensure the rapid perception of the risk of two-streams innovation transformation, strengthen the establishment of the risk assessment criterion of innovation transformation, so as to improve the environmental adaptability of two-streams innovation transformation, reduce transformation risk, and promote the newstream innovation transformation.
