The automotive industry dynamic character, which is shaped by fierce competition among car manufacturers, fluctuating customer demands and strong effect of environmental forces, provides an ideal context for examining the performance outcomes of MC and DC in non-static environments. This study aims to show whether better financial performance can be achieved through an integrated MC and DC framework; if the level of environmental dynamism (ED) influences the utilization of MCs; and the impact of MC and DC convergence on firm performance by using emerging market data, which is rare in the extant literature.\u0000\u0000\u0000Design/methodology/approach\u0000This paper empirically investigates the role of MCs on the relationship between DCs and firm performance and the effect of ED in marketing capability development through a study of 162 top level managers from the automotive industry in Turkey using multiple regression methods.
