Final answer:
The power balance in today's supply chain can shift due to factors like technology, globalization, and increased competition facilitated through B2B platforms. Policies and investments in technology and labor can also influence the power dynamics.
Step-by-step explanation:
The power dynamics in today's supply chain can vary between the supplier-manufacturer relationship and the supplier-retailer relationship. Factors such as advancements in technology, globalization, and market competition have influenced these dynamics significantly. With the emergence of business-to-business (B2B) websites, suppliers and buyers across the world can find each other more easily, increasing competition and potentially shifting power balances.
Also, in regard to supply chain resilience, there is an increasing need for policies, technology improvement, and respect for labor rights to maintain efficiency during national emergencies. Companies that invest in these areas, potentially, could gain more power within the supply chain. Finally, the ease of long-term expansion for producers suggests that those capable of scaling production may find themselves in a position of greater power over the long run.
