Information sharing has been cited as one of the major means to enhance supply chain performance. It allows
companies to better coordinate their activities with their supply chain partners that lead to increased
performance. This study conceptualises and assesses several factors that influence the degree of information
sharing in supply chains, namely integrated information technologies, internal integration, information quality
and costs–benefits sharing. The relationship between the degree of information sharing and organisational
performance is then tested. Data from 150 manufacturing companies were collected and proposed relationships
are examined using structural equation modelling. The results show that integrated information technologies and
information quality have positive influence on the intensity of information sharing. However, internal integration
and costs–benefits sharing do not relate to the intensity of information sharing. This study finds that information
sharing does not directly relate to organisational performance. Its relationship is mediated by collaboration
practices with supply chain partners. This suggests that information sharing is essential but insufficient by itself to
bring significant performance improvements.
