Innovation as a determinant of suppliers’ roles and performances: an empirical study in the food machinery industry

Abstract

The basic premise of this study is that suppliers, in order to compete successfully in the marketplace, have to develop certain innovative capabilities that, in turn, depend on the type of relationship that is established with customers (in other words, the strategic role assumed by the supplier in the supply chain). Based on a study of 198 suppliers operating in the food packaging machinery industry, structural equation modelling has revealed that customers actually assign suppliers different roles and give them varying levels of responsibility in the product development and manufacturing stages. These roles are correlated to the supplier's distinctive innovation capabilities. Clustering analysis is used to divide the suppliers into homogeneous groups. Innovative capabilities are not only associated with traditional competencies in R&D and product/process innovation but also in supportive capabilities in the form of absorptive capacity, technological scanning, innovation-oriented culture, skills and know-how of individuals and managerial practices. The impact of different innovative capabilities (both technological and managerial) on critical performance factors such as price, quality, time and flexibility is measured for each type of supplier in turn. The research findings lend support to the hypothesis that the level of investment in technology and the acquisition of specific managerial capabilities are, to a large extent, a determinant of supplier–customer interdependence.
