Strategic knowledge disclosure is an important channel for enterprises to participate in open value creation,but its relation-ship with product innovation performance is not yet clear.Based on the resource orchestration theory,the mechanism and boundaries of the impact of strategic knowledge disclosure on product innovation performance were explored in this paper,and a fixed-effects negative binomial regression model was constructed for empirical analysis by using the 213 Chinese automobile manufacturing enterprises'experi-ential data.The results showed that strategic knowledge disclosure can enhance product innovation performance.The influence mecha-nism test indicated that strategic knowledge disclosure can drive product innovation through channels such as enhancing relational reci-procity,releasing cooperation signals,and expanding the public knowledge pool.The moderating effect test found that knowledge mod-ularization capability,knowledge retrieval capability,and the synergy of the two can positively moderate the relationship between stra-tegic knowledge disclosure and product innovation performance,and in terms of difference in effects,the moderating effect of knowl-edge modularization capability is the strongest.This paper has expanded the research on the mechanism of strategic knowledge disclo-sure to promote product innovation from the perspective of external knowledge acquisition,and it will provide some reference for how enterprises utilize dynamic capabilities to facilitate open product innovation.
