Since the 1970s, we have witnessed unprecedented diff usion of digital technologies in both speed and geographic coverage. These technologies are pervasive and disruptive, and lead to profound shifts and transformations in societies and economies.

Many claim that emerging network externalities are the principal phenomenon driving the process of technology diff usion and determining its in-time dynamics. This book analyzes the unique role network eff ects play in the process of digital technology diff usion.

Using the time span of 1980–2022 and data from over 180 countries, the authors examines the strength and determinants of emerging network externalities in the process of digital technology diffusion across the world. Moreover, using international case studies it traces the process of technology convergence and technology convergence club formation, intending to answer whether cross-country gaps are diminishing or rather growing, and if countries form unique ‘clubs’ within which a rapid convergence occurs.

Global Digital Technology Convergence is written for scholars and researchers in the fi elds of technology and innovation management, information and communication technology, economic development and the economics of innovation. .
