Impact of External Knowledge Inflow on Product and Process Innovation of Korean SMEs: Absorptive Capacity as a Mediator

Abstract

We examine the role of external knowledge inflow in improving the product and process innovation of Korean exporting small- and medium-sized enterprises (SMEs) in the textiles, apparel, and footwear industries. Building on the resource-based view (RBV), we investigate how five sources of knowledge inflow (suppliers, customers, competitors, universities, and government agencies) contribute to product and process innovation through absorptive capacity (AC) as a mechanism to explain the link between external knowledge inflow and innovation. Conducting a path analysis, we found that knowledge inflow from customers and government agencies had a positive effect on AC, subsequently enhancing product and process innovation. Additionally, knowledge inflow from universities and government agencies also affected process innovation and product innovation, respectively. We also demonstrated the mediating role of AC in the relationship between external knowledge inflow and innovation. Korean SMEs should thus invest in developing the knowledge sources of customers, universities, and government agencies to enhance AC and innovation.
