Abstract: Based on evolutionary game theory, the innovation modes selection of enterprises were analyzed, then the impacts of absorptive capacity on innovation modes selection were discussed. The results show that, with growth of absorptive capacity, the expected return of enterprises increases no matter whether enterprises select radical innovation mode or incremental innovation mode, but the expected return increases more remarkably when enterprises select radical innovation mode; the growth of absorptive capacity can lead enterprises to select radical innovation mode in higher probability and select incremental innovation mode in lower probability.
