Contingent effects of close relationships with suppliers upon independent restaurant product development: A social capital perspective

Despite recommendations that the restaurant industry more readily engage suppliers within their operations in order to expand capabilities, associations with restaurant business performance and supplier relationships remain unexplored in today's current restaurant literature. This study assessed restaurant-supplier relationships from the social capital perspective and evaluated roles social capital played in product enhancement and new product development within the independent restaurant context. Results demonstrated that independent restaurant product enhancement was positively and linearly associated with social capital derived from restaurant-supplier relationships. Results also found that building social capital within restaurant-supplier relationships positively influenced new product development, but when taken to an extreme, it exhibited a negative association through an inverted curvilinear effect. Results provide new insights for future research and practice regarding independent restaurant supply management practices.
