The purpose of this book is to draw up a picture of the transformations in the innovation systems induced by globalization - or globalization. We understand the latter as the existence of new macroeconomic solidarities. These are attested since about the middle of the 1980s, with the observation of a tripolar world drawn up by Kenichi Ohmae. The book intends to explain all theories of globalization, as well as to clarify its relations with innovation. It constitutes an unprecedented synthesis on this theme, illustrated by examples from many sectors of activity.
