Business to Business (B2B) e-commerce promises a radical shift in the way in which enterprises trade with each other. How will this affect agricultural producers and manufacturers in developing countries? Will it open new and cheap access to global markets? Or, conversely, will it entrench the power of global buyers? Or will developing country producers find themselves marginalised by e-commerce trading relationships that depend upon not only sophisticated communication technologies, but also efficient logistics systems, payment systems and certification? IDS research sought to answer these questions.
