Although previous studies have considered the antecedents and outcomes of absorptive capacity, much remains to be learned on this subject. Firms need to absorb breadth and depth of knowledge and form absorptive capacities that are contingent on various social capitals to improve innovation and performance. The purpose of this study is to explore the antecedents and outcomes of the breadth and depth of absorptive capacity from the perspective of social capital theory. Based on a sample of 218 Chinese firms, empirical results suggest that weak tie sources and knowledge breadth can enhance the breadth of absorptive capacity, and that strong tie sources and knowledge depth can strengthen the depth of absorptive capacity. The results also suggest that the breadth of absorptive capacity positively impacts the depth of absorptive capacity, and that both breadth and depth of absorptive capacity are positively related to innovation performance.
