Barriers to entry can protect existing firms from which of Porter's Five Forces?
A
Bargaining power of suppliers
B
Bargaining power of buyers
C
Threat of substitute products
D
Threat of new entrants
Verified step by step guidance1
Understand that Porter's Five Forces framework analyzes the competitive forces that shape every industry and market.
Identify that 'Barriers to entry' refer to obstacles that make it difficult for new firms to enter an industry.
Recall the five forces: (1) Threat of new entrants, (2) Bargaining power of suppliers, (3) Bargaining power of buyers, (4) Threat of substitute products, and (5) Industry rivalry.
Recognize that barriers to entry specifically protect existing firms from the 'Threat of new entrants' by preventing or limiting new competitors from entering the market.
Conclude that barriers to entry do not directly protect firms from the bargaining power of suppliers or buyers, nor from the threat of substitute products.
