The book "Local Cluster Development and Global Brain Circulation" by Cristiano Richter offers a comprehensive analysis of the role of high-tech clusters in the global economy. It examines how local clusters in emerging economies are connected to global networks and the impact these connections have on innovation and production dynamics. A central theme is inter-cluster brain circulation (IBC), which describes the exchange of knowledge, technologies, and practices between different clusters. The book highlights the complex interactions between larger, established clusters and smaller, emerging clusters, and discusses the governance strategies that are crucial for the growth and development of these clusters. The insights from this study are of great significance for understanding cluster connectivity and the strategies that emerging economies can employ to succeed in global competition.
