Cultural proximity consists in shared language, codes , and norms of communication and exchange between actors. It is generally considered important for organizations, enhancing communication and facilitation interaction between actors. In such situation, diversity is often seen as a source of richness and originality. However, high levels of proximity might create some risk, leading to lock-in and inertia, with a negative impact on the innovativeness of the organization.While the role of cultural proximity is subject to much debate within organizations studies, a comprehensive understanding of cultural proximity remains elusive. This book explores the organizational implications of the concept of cultural proximity, delving into the managerial challenges posed by diversities and similarities in culture within a business environment using different levels of analysis. The key messages of the present book, grounded on original empirical evidence, can be summarized as follows: cultural proximity is a key factor for managing innovation in present times; innovation requires a deliberate orchestration of the dichotomy between cultural proximity/cultural diversity; there are specific circumstances where proximity can be beneficial for managers and entrepreneurs.The book will be of value to researchers, academics, managers, and students in the fields of management science, human resource management, innovation studies, and organizational studies.
