If the primary determinant of a firm’s profitability is the attractiveness of the industry in which it operates, an important secondary determinant is its position within that industry. Even though an industry may have below-average profitability, a firm that is optimally positioned can generate superior returns.

 
A firm positions itself by leveraging its strengths. Michael Porter has argued that a firm’s strengths ultimately fall into one of two headings: cost advantage and differentiation. By applying these strengths in either a broad or narrow scope, three generic strategies result: cost leadership, differentiation, and focus. These strategies are applied at the business unit level. They are called generic strategies because they are not firm or industry dependent. The following table illustrates Porter’s generic strategies:

Barriers to Entry / Threat of Entry

It is not only incumbent rivals that pose a threat to firms in an industry; the possibility that new firms may enter the industry also affects competition. In theory, any firm should be able to enter and exit a market, and if free entry and exit exists, then profits always should be nominal. In reality, however, industries possess characteristics that protect the high profit levels of firms in the market and inhibit additional rivals from entering the market. These are barriers to entry.

Buyer Power

The power of buyers is the impact that customers have on a producing industry. In general, when buyer power is strong, the relationship to the producing industry is near to what an economist terms a monopsony – a market in which there are many suppliers and one buyer. Under such market conditions, the buyer sets the price. In reality few pure monopsonies exist, but frequently there is some asymmetry between a producing industry and buyers. The following tables outline some factors that determine buyer power.

Threat Of Substitutes

In Porter’s model, substitute products refer to products in other industries. To the economist, a threat of substitutes exists when a product’s demand is affected by the price change of a substitute product. A product’s price elasticity is affected by substitute products – as more substitutes become available, the demand becomes more elastic since customers have more alternatives. A close substitute product constrains the ability of firms in an industry to raise prices.

Potensi pengembangan produk substitusi
Produk substitusi merupakan produk lain yang bias menggantikan produk tertentu dalam memenuhi kebutuhan yang sama. Semakin banyak tersedia dan mudah diperoleh produk substitusi dari suatu industri semakin mengancam industri tersebut. Artinya persaingan tidak hanya bersal dari produk sejenis tetapi juga persaingan dariu produk lain yang bias menggantikan produk tersebut. (more…)

A MODEL FOR INDUSTRY ANALYSIS

The model of pure competition implies that risk-adjusted rates of return should be constant across firms and industries. However, numerous economic studies have affirmed that different industries can sustain different levels of profitability; part of this difference is explained by industry structure.

Michael Porter provided a framework that models an industry as being influenced by five forces. The strategic business manager seeking to develop an edge over rival firms can use this model to better understand the industry context in which the firm operates.
