Corporate effects as competitive heterogeneity:construct and scale development

This paper aims at developing the competitive heterogeneity construct and the related scale through a three-step methodology. First, we define the competitive heterogeneity construct as a multidimensional construct and clarified the relationship with its dimensions, and between these and their measures; then, we carry out face validity through literature review and expert validation; finally, we do a two-step empirical analysis to assess the competitive heterogeneity construct, the relationship with its dimensions, and the link between these and their measures. Our research suggests that competitive heterogeneity is a superordinate reflective multidimensional construct, and that its dimensions represent unidimensional reflective constructs
