Exploring Dynamic Embeddedness: a Network Analysis of the Global Pharmaceutical Industry 1991-2012
نویسندگان
چکیده
We analyze the global pharmaceutical industry network using a unique database that covers strategic transactions (i.e. alliance, financing and acquisition collaborations) for the top 90 global pharmaceutical firms and their ego-network partnerships totaling 4735 members during 1991-2012. The network evolution is traced via a novel method based on the concept of dynamicity that quantifies individual network members (i.e. actors) contribution to the longitudinal period. Specifically, we observe dynamic embeddedness defined for key network centrality measures, and capture the impact of the 2007-2008 global financial crises and the subsequent global and Eurozone recession effects on the strategic transaction flows between the industry’s key players as well as their partners. Results suggest the feasibility of dynamicity as a dynamic network indicator as well as the importance of constellation strategic transactions in the study of large network perturbations.
