Abstract:s:This paper mainly discusses the mechanism of the technological logic orientation on the innovation behavior of start-ups, and the impact of the innovation behavior of start-ups on the innovation performance under the technological logic orientation. Based on the development stages of start-ups, this paper empirically studies the relationship between technological logic orientation, innovation behavior and innovation performance. Empirical research finds that the coupling form of technological innovation behavior and organizational institution innovation behavior is different in different development stages of start-ups under the technological logic orientation, and only technological innovation behavior is adopted in the founding stage. In the survival stage, start-ups will adopt both technological innovation behavior and organizational institution innovation behavior, but it will focus on the organizational institution innovation behavior and the technological innovation behavior as the supplement. In the growth stage, the start-ups will also adopt two kinds of innovation behavior, but at this time, it will take the technology innovation behavior as the main body and the organizational institution innovation behavior as the supplement. To a certain extent, Adopting the strategy of technological logic orientation will improve the innovation performance of start-ups.
