E-commerce diffusion in high-income developing countries : determinants of e-commerce adoption and post-adoption of Saudi enterprises

The ubiquitous nature of e-commerce in developing countries demands an innovative conceptualisation of its adoption and post-adoption that responds to various contextual circumstances. Despite efforts made to investigate e-commerce adoption in developing countries, the literature suggests that the focus is mostly on a single perspective of a single adoption stage and concentrates on specific locations. To extend our understanding of the phenomenon, an exploratory phase is undertaken through a literature review as well as an exploratory investigation. Consequently, a holistic framework is integrated that includes organisational and environmental factors, in addition to innovation attributes. The framework is empirically validated using a statistically representative sample size of 384 enterprises of various sizes and industries in a highincome developing country from a poorly investigated region. The empirical analysis shows that perceived benefits as well as mimetic pressure are more influential for the adoption of e-commerce and scope of use than the utilisation amongst adopter organisations. In addition to coercive pressure, the readiness of financial institutions, IT industry and the government affect the scope of ecommerce use. For adopter firms, the extent of e-commerce adoption is influenced by business process readiness, government readiness and security. Commitment, especially from top managers, is a key determinant that links e-commerce adoption to the extent of adoption and the scope of e-commerce use. The findings indicate that the proposed models are sufficiently reliable in discriminating not only adopters from non-adopters, but also the extent of adoption and use across the value chain. Together, this research offers a multi-perspective framework of e-commerce adoption and post-adoption in highincome developing countries and identifies the factors that affect ecommerce adoption, and how these effects vary across adoption stages. It presents insight into various issues that influence e-commerce adoption and post-adoption in this littleexplored region, which will be of interest to researchers, practitioners and policy makers.
