〔戦略経営論〕第6回 業界構造分析③

Summary

The lecture explains how to use Porter’s Five Forces to assess an industry’s profit potential, with particular attention to bargaining power between buyers and sellers. It then considers how industry structures can change and how companies can choose a strategic position.

1. Buyer and seller bargaining power

• Buyers generally want to pay less, while sellers want to charge more. Their competing interests shape prices and the distribution of profits.
• The same relationship applies throughout a supply chain. For example, an airline may bargain with passengers as a seller, but bargain with oil companies and aircraft manufacturers as a buyer.
• Buyers and sellers are not necessarily equal. The stronger party can influence the terms of trade, including price.

A central principle: Bargaining power depends in part on how replaceable each party is to the other.

• If one buyer accounts for a large share of a seller’s revenue, that buyer can exert strong pressure. Losing the buyer could seriously threaten the seller, making it more likely to accept a price reduction.
• If the seller has many other customers, losing one buyer is less damaging, and that buyer’s bargaining power is weaker.
• The lecturer connects this to the tofu-shop assignment: a supermarket that accounts for much of a tofu maker’s sales can demand discounts or threaten to switch to a competitor.
• Small companies can sometimes improve their bargaining position by combining their orders through centralized purchasing, gaining the leverage of a larger customer.

2. Factors affecting bargaining power

The lecture highlights several factors that can make a party more or less powerful:

• How significant a buyer is to the seller: A buyer responsible for a large share of sales is difficult to replace.
• Standardization and differentiation: If a seller’s product is undifferentiated and readily available elsewhere, buyers can switch more easily.
• Switching costs: When it is easy and inexpensive to change suppliers, buyers have more alternatives and greater leverage.
• The threat of entering the other party’s business: A business partner that could move into the same industry may become a potential competitor. The possibility of this kind of integration can affect negotiations.
• Information asymmetry: A party with information the other side lacks may gain an advantage. However, information that becomes widely known can lose its value or be used against its holder.

The lecturer uses examples from business, international relations, and personal relationships to illustrate the general point that a party’s power often depends on how difficult it would be for the other party to do without it.

3. Protecting information and negotiating ideas

• Cost and purchase-price information can be strategically valuable. Revealing a company’s costs may give customers a basis for pushing prices down, so the lecture advises keeping such information confidential.
• Information asymmetry can help a negotiator, but its advantage disappears if the other party acquires the same information.
• Selling an idea creates a particular problem, sometimes called the disclosure paradox: a buyer may need to understand an idea to judge its value, but once the idea is disclosed, the buyer may be able to use it without paying.
• This problem can also affect startups negotiating with large companies. Disclosing a technology or business idea may weaken the startup’s negotiating position or enable imitation.
• Collaboration and open innovation can create value, but they require clear prior agreements and fair arrangements for compensating those who contribute knowledge or ideas.

4. Substitutes and changing cost-performance

• Substitutes are alternatives that can serve a similar purpose, such as margarine for butter, digital photography for film, or email for letters.
• Complementary goods are used together, such as coffee and sugar, or cameras and film.
• A substitute becomes a more serious threat when its cost-performance improves rapidly. A product that seems inferior today may become a competitive alternative as its performance rises relative to its price.
• The lecture’s computer-storage example illustrates how quickly this kind of improvement can change competition.

5. Applying the Five Forces: Automotive batteries

The lecture applies the framework to automotive batteries:

• Competition within the industry: Described as relatively weak because there are few players, although the product itself is fairly standardized.
• Threat of new entrants: Some overseas entrants, particularly from China, may enter the Japanese market, though their effect on established manufacturers is described as limited at present.
• Threat of substitutes: Considered low because there is no direct replacement technology identified in the example.
• Supplier bargaining power: Considered limited because lead, a main material, is widely available.
• Buyer bargaining power: Considered strong. Vehicle manufacturers and major auto-parts retailers purchase in substantial volumes and can press battery makers for lower prices.

The overall implication is that a significant share of potential profit may be transferred to large buyers. The analysis helps identify where pressure on industry profits comes from.

6. Industry structure is not fixed

• Porter’s framework is useful for analyzing an industry at a particular point in time, but it can encourage a static view.
• Industry structures can change because of new technology, new entrants, regulation, and shifts in customer behavior.
• The lecture uses broadcasting as an example: changes in viewing habits, online services, and alternative distribution channels could weaken traditional broadcasters’ position.
• It also describes how the internet changed the travel industry. Customers can book directly through airline websites, bypassing the traditional travel agency role. Travel agencies therefore need to find new sources of business.
• The lecturer emphasizes that companies are not necessarily trapped in their current industry position. They may try to reshape the market, develop new customers, or move into a different position.

7. Porter’s generic strategies and positioning

The lecture presents Porter’s basic strategic choices:

• Cost leadership: Compete through lower costs.
• Differentiation: Offer distinctive value that customers recognize.
• Cost focus: Pursue a cost advantage within a narrower market.
• Differentiation focus: Serve a narrower market with a distinctive offering.

The lecture warns against trying to combine incompatible priorities without making clear choices. Porter calls this being “stuck in the middle”: a company that compromises on both cost and differentiation may fail to achieve either advantage. Companies should decide what they will prioritize and what they will not compromise.

Automakers are used as illustrative placements in the strategy framework: Toyota is presented as a broad-market, cost-oriented example; BMW as differentiated with wider reach; Suzuki and Daihatsu as cost-oriented with a narrower focus; and Porsche and Ferrari as focused, differentiated examples.
