Abstract: S&T-based enterprises are regarded as the most dynamic, potential and growth-oriented innovation groups, but they often step into the predicament of " can’t get in, can’t stand, can’t grow up” because of " new entry defects”. In the study of this universal phenomenon, the discussion of the technical strategy of the initial stage is relatively scarce from the perspective of the evaluation of technological innovation attributes. Firstly, it traces and sorts out the research status of technology-based enterprises and the research status of the initial period. Secondly, it summarizes the technical innovation attributes and evaluation methods from the perspective of " technology”, and then reviews the technical strategy research. Under the premise of open thinking, the paper reviews the related research on patent portfolio and technology alliance strategy, and analyzes the different technological development logic between them and traditional technology strategy. Finally, the research lack and future research directions in this field are proposed.
