5 Conclusions
This study analyzes the correlation among integrative IT, SCI, and firm performance. The findings of this research are summarized as follows. The results show that integrative IT is positively associated with firm performance through SCI (H1 and H3). This suggests that firm performance is engendered by integrative supply chain strategy (integrative IT and SCI). This result is consistent with that of the study by Vickery et al. (2003), which emphasized the importance of integrative supply chain strategy. However, the results of this study show that integrative IT does not have a positive correlation directly with firm performance (H2). Such a result is in agreement with the study by Tippins and Sohi (2003), Kim et al. (2011), but not with that of Sanders and Premus (2005). If this is interpreted on the basis of the results of the study by Vijayasarathy (2010), it can be seen that the use of IT has different impacts on performance depending on the extent of partnership on the supply chain. Thus, it is considered that in the relationship between IT and firm performance, a new approach such as business process-oriented view arguing that performance is yielded through the primary influence of IT is necessary rather than a traditional view that sets up their direct correlations.
