Book excerpt: Analyses of globalization and global governance frequently identify business actors, in particular TNCs, as the major beneficiaries of assoviated changes in the political capacities of state and non-state actors. This book examines in a systematic, comprehensive and theoretically grounded manner to what extent and in which aspects the political power of business really has risen. It thus analyses developments in business' lobbying, agenda- and rule-setting, and political communication activities at the national and supranational levels from a three-dimensional perspective on power. On that basis, Understanding Business Power in Global Governance delineates qualitative and quantitative changes business' political activities and links them to a differentiated view of developments in the instrumental, structural, and discursive power of business in the globalized world.
