Manufacturer structural embeddedness and the network rent: the intervening role of relational embeddedness in the triadic supply chains

The purpose of this paper is to investigate whether the manufacturer that occupies the central position in the triadic supply chain is capable of enhancing relationships within both dyads to produce the network rent and extra profit shared among all supply chain actors.

The paper opted for an exploratory study using a survey of triads forming supply chains. To reveal the capability of yielding the network rent in the examined triads, multiple regression analysis with Interaction effects was used. Having confirmed the existence of supernormal profit, the partial least square path model was developed to investigate the effects of manufacturer structural embeddedness on relational embeddedness and the resulting impact on the network rent.

The obtained findings show that manufacturer structural embeddedness has a direct and positive effect on relational embeddedness and relational embeddedness of two dyads (represented as a higher order factor) has a direct and positive effect on the network rent. In addition, relational embeddedness mediates the positive relationship between manufacturer structural embeddedness and network rent, as the null model with no mediation appears to underestimate the direct and positive effect between manufacturer structural embeddedness and the network rent.

The study makes three key contributions. First, it extends the application of both relational and structural embeddedness to grasp the network architecture of the triadic supply chain. Second, the concept of manufacturer structural embeddedness is used to elaborate on the role of the manufacturer in establishing relationships of high quality with the supplier and the customer. In connection to the previous point, the calculated network rent demonstrates that establishing collaborative relationships in triadic supply chains may bring a significant supernormal profit, derived as the outcome of mutual interplay between the relational performances of two dyads.

The study shows that manufacturers intending to use their central position to develop collaborative relationships with both partners, and the supplier and the customer, ought to appreciate the role of social ties embedded in interorganizational networks. The paper also implies that in parallel with using formal contracts as a governance mechanism, the manufacturer centrally positioned in the triadic supply chains ought to deliberately shape relational embeddedness of both dyads. Finally, managers can consider the ways to enhance relational embeddedness in a triad by improving relational embeddedness of a certain dyad.

This study provides a novel framework for studying two basic dimensions of embeddedness (structural and relational) and their impact on the network rent in triadic supply chains that goes beyond the dyadic perspective and incorporates the extended supply chain.
