The main objective of the study is to investigate the impact of the supply chain innovation, supply chain transaction cost, supply chain risk and supply chain responsiveness as antecedents of the supply base and its complexity. The study attempted to understand the way in which transaction costs, supplier responsiveness, supplier innovation, and supply risk are affected by the supply base complexity, and the study also expressed them in liner relationships. With the supply base complexity, it became easier to understand ways for managing supply base. |
