Knowledge absorptive capacity and innovation performance in KIBS

Purpose The purpose of this paper is to discuss whether the three knowledge sources, knowledge input, knowledge spillover and knowledge absorptive capacity, really increase the innovation performance of firms in the Taiwan IC design industry, one of the most important knowledge‐intensive business services (KIBS) industries in Taiwan. Design/methodology/approach Based on the knowledge‐based theory, this study uses pooled regression analysis and tests with fixed effect model to analyze the influence of three knowledge sources on innovation performance in the KIBS sector. Findings The results demonstrate that: knowledge input is positively related to innovation performance; knowledge spillover effect is partial positively to innovation performance; and knowledge absorptive capacity is positively related to innovation performance. Originality/value The paper advances the concept of absorptive capacity by defining it as the interactions between knowledge input and knowledge spillover and refines the measurement of absorptive capacity as the multiplication of knowledge input and knowledge spillover effects. Moreover, knowledge spillover effects and knowledge absorptive capacity are both divided into four kinds which help us distinguish clearly different sources of knowledge spillover and absorptive capacity. In addition to that, this study also contributes to the empirical evidence to innovation activities by using firm‐level micro data.
