In Porter's model, what is the sixth force that can influence market attractiveness?

• A. Government
• B. Customers
• C. Technology
• D. Competitors

Answer: (A)

Government policy and regulation can shift how attractive an industry is beyond the five forces. While the five forces capture competitive dynamics from rivals, suppliers, buyers, substitutes, and entry barriers, government actions shape those dynamics from the outside. Through regulation, licensing, tax regimes, subsidies, procurement rules, and competition policy, the government can raise or lower barriers to entry, alter costs, influence supplier or buyer power, encourage or limit substitutes, and affect rivalry. Because these policy and regulatory influences can broadly tilt profitability across industries, they’re often described as a sixth force that can influence market attractiveness. The other options—customers and competitors—are already part of the five forces, and technology affects dynamics but is not typically treated as an extra formal force.
