For students studying GCSE Business, understanding market share is important as it indicates how well a business is performing relative to its competitors. A higher market share suggests a strong competitive position, while a lower market share may suggest it needs to improve its business strategies. Market share can influence pricing, marketing, and production decisions, making it a critical measure for assessing business success.
