Final answer:
The concentration of marketing activities refers to the practice of centralizing marketing efforts in one or just a few locations worldwide, a trend often associated with globalization and multinational corporate strategies.
Step-by-step explanation:
The term concentration of marketing activities refers to the extent to which activities related to marketing are performed in one or a few locations. This is often a result of globalization, which affects economic growth and the integration of markets worldwide. Having marketing activities concentrated in few locations allows a business to unify its marketing efforts and possibly gain economies of scale. However, this concentration can also lead to a dependence on these locations, where an estimated 25% of regions rely on other areas for at least one crucial type of good. Furthermore, the existence of multinational corporations, like McDonald's, demonstrate the widespread diffusion of business and cultural entities, underscoring the interconnectedness of global markets and opportunities for competition beyond local boundaries.
