Information Sharing in Global Supply Chain Alliances

ABSTRACT The post–WWII economic expansion of economies such as Japan, South Korea, Hong Kong, Taiwan, Singapore, and more recently China and India was enabled to a significant degree by the increasingly complex, global supply chain networks of large Original Equipment manufacturers (OEMs) in the United States, European Union, and Japan. By linking buyers and suppliers across countries and industries, supply chain management (SCM) practices have a large impact on the economic fortunes of companies and countries throughout the world. Nowhere has the effect of this mutual interdependence been felt more strongly than between the U.S. companies and the Asia-Pacific market. Although the benefits of SCM are well documented, some evidence suggests that the reality of SCM implementation can create additional pressures for suppliers. We identify key problem areas experienced by suppliers and their link to the type of information shared by buying firms. The problem area experienced by most suppliers relates to issues of dependence in the alliance. Mere information sharing is insufficient for a successful alliance, and more information can be associated with a number of problems. For example, lack of information sharing can be associated with a supplier's perception of the buyer expecting excessive support. However, greater information sharing can be associated with a supplier's perception of the buyer passing on an excessive burden. Sharing of financial information is perceived as intrusive and controlling. These apparent contradictions uncover the complexity of the supply chain alliance. The moderating factors appear to be open communication and joint sharing of problem solving procedures—factors identified by suppliers that define a world-class buyer.
