Abstract: Based on the theory of organizational learning and absorptive capacity, this paper incorporates the knowledge search rhythm and knowledge reuse trajectories into the research framework from the time dimension, and analyses the moderating effect of knowledge search rhythm, knowledge reuse frequency and knowledge reuse lag on the relationship between knowledge search magnitude and firm innovation performance.Patent data from 81 firms in the wind power industry from 2008 to 2017 and the negative binomial regression model are used to verify the relevant assumptions. It is found that the new knowledge search magnitude has an inverted U-shaped effect on firm innovation performance; the rhythm of knowledge search positively moderates the relation between knowledge search magnitude and firm innovation performance; the knowledge reuse frequency negatively moderates the relation between knowledge search magnitude and firm innovation performance; and the knowledge reuse lag negatively moderates the relation between knowledge search magnitude and firm innovation performance.
