Which factors are included in Porter's 5 Forces model?

Porter's 5 Forces model is a framework designed to analyze the competitive forces within an industry, which can influence its overall attractiveness and profitability. The correct choice identifies the five key factors that form this model: potential new entrants, buyer power, supplier power, threat of substitutes, and rivalry among existing competitors.

Potential new entrants refer to the barriers that exist for new companies trying to enter a market. The ease or difficulty with which new competitors can arise affects the competition landscape significantly. Buyer power assesses how much influence customers have on pricing and quality, which can pressure companies to enhance their offerings. Supplier power reflects the control suppliers have over pricing and quality, affecting a company's cost structures and profitability. The threat of substitutes measures the availability of alternative products that can fulfill the same need as the original offering, creating additional competition. Lastly, rivalry among existing competitors examines how fiercely businesses compete for market share and resources, which ultimately impacts profitability.

In contrast, the other choices include factors unrelated to the five forces framework. While market growth and product demand are important for understanding market dynamics, they do not fit into the structural analysis of competitive forces. Similarly, innovation and market share may play a role in success but are not part of the five forces that Porter outlined. Lastly,
