An evolutionary approach to understanding international business activity is explored in this assignment. The co-evolution of multinational enterprises (MNEs) and the institutional environment is examined as a key factor in shaping international business activity. The concept of MNEs' co-evolution with the institutional environment highlights the dynamic relationship between these two entities, emphasizing that both evolve simultaneously over time. This approach recognizes that institutions are not fixed or predetermined but rather are shaped by the actions of MNEs and other actors within the international business environment.
