This study aims to better understand how a firm’s resources can be used to improve performance of supply chain. Extending prior research on the resources-based view, this study develops an integrated model, which delineates the relationship among three IT-related resources, absorptive capacity, and supply chain (SC) process performance. Through a field survey of 205 managers from Taiwan’s firms, most proposed hypotheses are supported, showing that IT-related resources in terms of managerial skills and partner support affect absorptive capacity, which in turn influences performance. This paper offers a new perspective on using firms’ resources from which their SC performance can be improved.
