This paper applies Porter's Five Forces framework to the carbonated soft drink (CSD) industry, evaluating the competitive dynamics between Coca-Cola and Pepsi. It examines barriers to entry, the threat of substitutes, customer buying power, supplier bargaining power, and the intensity of rivalry between the two dominant players. The paper also explores how Coke and Pepsi have maintained their duopoly through consolidation, strategic pricing, and control of distribution channels. Additional considerations include bottler power, location strategy for bottling operations, structural changes from the mid-1980s onward, and how globalization — particularly in emerging markets — may sustain their competitive advantage.
Threat of Entry of New Competition: Low. The economy of scale within the carbonated soft drink (CSD) industry requires an enormous amount of capital to enter this market, making this threat relatively insignificant.
Threat of Substitutes: High. Colas now compete against many different categories of drinks. Health and medical experts also contribute to this threat by steering consumers away from sugary carbonated beverages.
Threat of Customer Buying Power: Medium. The customer base will purchase soft drinks with disposable income, but harsh economic conditions force consumers toward cheaper alternatives.
Threat of Suppliers' Bargaining Power: Low. Concentrate providers are significantly tied to the success of this industry and have few outlets with comparable buying power.
Threat of Intense Rivalry: Medium. The decades-long cola wars between Pepsi and Coke explicitly demonstrate a relatively two-sided competitive battle.
This industry is both profitable and attractive for concentrate producers (CPs) due to the simple and minimal ingredients contained in the product and the willingness of bottlers to absorb packaging and higher labor costs.
Coke and Pepsi have created strong barriers to competition by acquiring and controlling all threatening products. When bottled water became a profitable category, both companies easily shifted into that new market, demonstrating the power of controlling a broad industry portfolio.
Bottlers do hold power, but only when their efforts are combined. The widespread influence of the larger CPs makes it difficult for bottlers to organize collectively and reduce costs.
Since Coke and Pepsi have divided the market between fountain and retail sales, it appears that an informal agreement to avoid destroying the market has emerged. Their true competitive advantage arises when consumers choose CSD over free water or alcoholic beverages.
