Emerging economies are affecting global supply chains in several ways: 1) The economic center of gravity is shifting towards Asian and emerging economies due to their lower costs, strategic locations, and growing middle classes. 2) This is challenging existing supply chain models and infrastructure as logistics and transportation networks struggle to keep up with increasing trade volumes to and from these new economies. 3) Improvements in areas like customs processes, infrastructure, and reducing trade barriers can significantly boost trade and business profitability by lowering supply chain costs and inefficiencies.
