Final answer:
A shift in demand or supply is a change in market conditions altering trading willingness, while a movement along a curve is a response to price changes. Technology and globalization have expanded market access and competition, significantly through B2B platforms.
Step-by-step explanation:
The difference between shifts of demand or supply and movements along a demand or supply curve is fundamental in economics. A shift in demand or supply refers to a change in the market conditions that alters the willingness of consumers or producers to buy or sell at all prices, such as income levels, preferences, number of consumers, or resource costs - leading to a new demand or supply curve. In contrast, a movement along a demand or supply curve is a response to a change in price for the good or service, representing an increase or decrease in the quantity demanded or supplied without shifting the original curve.
Technological advancements and globalization have transformed the market landscape, providing the ability to access global markets through the internet, affecting local and international competition. These changes have also facilitated the emergence of business-to-business (B2B) platforms that enable international trade and procurement in ways traditional commerce networks cannot match.
