Moderating Effects of Environmental Uncertainty on Supply Chain Integration and Product Quality: An Empirical Study of Thai Automotive Industry

Although effective and efficient supply chain management requires integrated business processes that go beyond purchasing and logistics activities, some doubts are expressed concerning the applicability of supply chain integration practices. Specifically, a careful literature search reveals that no studies have included the effect of environmental uncertainty on the relationship between supply chain integration and product quality. This study, therefore, represents an attempt to provide the contribution in the field by developing a model to explore the relationships and to fulfill the gap between the literature on supply chain integration and environmental uncertainty. The findings indicate that the effects of supply chain integration on product quality are moderated by environmental uncertainty as demonstrated by Chow tests. The results also provide managerial insights about environmental uncertainty-supply chain integration practices connection.
