With global economic development and growing international competition, supply chain collaboration has become both an important strategic and operational issue. The organisation therefore must rethink both its electronic business (e-business) and global supply chain management (SCM) strategies. The development of e-commerce technology can help with supply chain integration and improve firm competitive advantage. This thesis investigates electronic supply chain (e-supply chain) integration through business-to-business (B2B) electronic commerce (e-commerce) application in the Taiwanese information technology (IT) industry. The purpose of the study is to explore and understand the critical factors impacting on e-supply chain collaboration and relationship development. The aim of the study is the identification of the key impacts of B2B e-commerce on supply chain integration and collaboration. Six case studies of Taiwanese companies were investigated. They were all members of the government supported 'industrial automation and electronic business programme' (IAEBP) - e-supply chain project. A 'qualitative coding matrix' (QCM) approach was adopted to ensure that the qualitative data collected was analysed in a rigorous manner. The research findings indicate that organisational use of B2B e-commerce technologies to communicate and integrate primary buyers or customers, have a positive and significant influence on supplier performance and customer satisfaction. There are numerous factors influencing the successful implementation of B2B e-commerce technologies by the firms. This includes: manufacturers' efforts in e-business projects implementation; international technology transfers; knowledge sharing and business process integration; information and communication technologies (ICTs) investment; and developing supplier partnerships. In respect to small suppliers, in the sample these do not have appropriate information systems (IS) and they tend to lack the internal resources for linking together future or current inter-organisational information systems (lOISs). Therefore the e-commerce solution a firm decides upon needs to be in alignment with the needs and networking capabilities of their customers. A number of important implications are derived from the doctoral research and an emergent model is generated. This provides academic and practical insights into e-commerce technology as it impacts on supply chain collaboration.
