Multinationals are increasingly taking internationalised approaches to the ways in which they generate new knowledge and develop innovative new products from it in the pursuit of global competitiveness. These new perspectives in MNEs' technological behaviour open up important additional possibilities for those countries that play host to operations of these companies. This book analyses in detail the new dimensions in MNEs' approach to global competitiveness and the role played in this by overseas R & D units, and discusses the implications of this for host countries' growth and welfare.
