Non-R&D innovation increasingly plays a critical role in explaining firms' new product performance. Yet, there has been little research on the consequences and contingent mechanisms of non-R&D innovation for firms embedded in collaborative network environments. To address this research gap, we investigated a conceptual framework of non-R&D innovation using data drawn from Chinese manufacturing firms. First, we found that non-R&D innovation positively affects firms' new product performance. Second, we discovered that high R&D intensity positively strengthens the impact of firms' non-R&D innovation on new product performance. Third, we provided critical analysis of the role of non-R&D innovation in promoting new product performance, accomplished by enhancing R&D investment while simultaneously improving the degree of network embeddedness. Our findings extend both the non-R&D innovation literature and open innovation literature while providing managers with several key recommendations.
