This study aims to empirically investigate the influence of levels of supply chain integration (SCI) as a moderating variable on the relationship between corporate competitive capabilities (CCC) and business performance. Data was collected from a postal questionnaire from 135 Malaysian manufacturing SMEs. The data was tested using confirmatory factor analysis, cluster analysis and multi-group SEM analysis. The findings confirm that the levels of SCI in a given firm moderate the relationship between CCC and business performance for that firm. The study also contributes to the body of knowledge by expanding the understanding of levels of SCI as a moderator.
