Since years, e-business research is subject of many conferences and publications. While researchers and practitioners often focus on e-business systems and applications, so far little attention has been given to the development of innovative and sustainable e-business models and solutions. This publication fills this gap by discussing the following key issues: What are challenges and opportunities for international e-business? What are the barriers and risks for companies implementing e-business models? How can they succeed in the long-term? In this context, this publication provides in-depth studies of consumer needs, cultural requirements as well as conditions of economic efficiency and successful implementation of e-business solutions. It is intended for e-business novices as well as advanced researchers and practitioners.
