Through studies of four representative Chinese companies – Stone, Legend, Founder, and Great Wall – this book presents the development of China's information technology (IT), and that of the computer industry in particular, in the past two decades. It argues that such development has been built on a different technology learning process from the traditional, bottom-up, linear technology transfer approach that starts with importation substitution, followed by assimilation, absorption and localization, product redesign, and finally product design.
