#1 – Company Structure, Rivalry, and Strategy

This aspect of the theory focuses on the competition in the native markets that businesses have to excel against. The region in which the firms operate determines the structure and strategies to be framed to compete in the home market.

As a result, the strategies differ from nation to nation. For example, Italy, known for its fashionable clothing, will definitely have a different approach than Greece, which emphasizes tourism and related facilities.

In addition, rivalry plays an important role in driving every entity operating in the same sector to improve, innovate, and perform better than each other. Therefore, the businesses have to be consistent. This makes them trustworthy and reliable national companies around the globe in the long run.

#2 – Factor Conditions

Factor conditions include resources available to businesses that help them perform well. The availability of resources could be influenced by the skillset, strategies, infrastructureInfrastructureInfrastructure refers to fundamental physical and technological frameworks that a region or industry establishes for its economy to function properly.read more, or nature. For example, Italy performs well because of its ability to choose better fabrics; Greece’s tourism market is influenced by the weather, which might keep changing.

The natural resources constitute the basic factors, while the infrastructure, skilled experts, and capital form the advanced factors. A nation develops a real competitive advantage with the development of advanced elements. In contrast, the contribution of basic factors to regional advantage is comparatively lower.

#3 – Demand Conditions

The demand for a particular product or service also plays an essential factor. Porter Diamond model’s third attribute indicates how the increase in demand for an item among local customer boosts the growth of a brand or business.

When customers want a product, businesses strive to improve the quality and live up to their expectations. As a result, they become competent enough to acquire the number one position on the global platform.

Another factor that influences business growth is the complementary services that lend support to the companies of national advantage. For example, the tourism services in Greece would never be the best if the accommodation facilities and food units over there did not support the industry.

#5 – Government

The government also plays a vital role in developing and retaining the competitive advantage by offering a conducive environment for businesses to flourish. This includes developing a robust infrastructure, ensuring fair market practices, developing education institutions, etc.

#6 – Chance

In addition, chance or luck may also contribute to competitive advantage or disadvantage. For instance, unpredictable events like wars, natural disasters, political situations, etc., can positively or negatively impact an industry or nation, creating a competitive advantage or wiping it off.


Let’s consider the following Porter Diamond model example:

The car manufacturing industry of Germany is one of the best examples to be cited here. The economy’s best sector complies with all the attributes and, therefore, strives through global challenges easily. With several competitors in the home market, car manufacturers continuously innovate and excel. As a result, the nation manages to have the best car models. 

Having no speed limits and an aspiration of citizens to have a quality and speedy life encourages the demand for high-speed luxury cars in the nation. Besides, skilled resources like car engineers from globally-recognized German universities give car manufacturers an edge over others. Thus, the demand conditions and factor conditions are all met.

Next, the support from the metal industries that offer the best spare parts to the car manufacturers tends to be the best support system for the national market. Besides, the German government’s support in the form of better infrastructure and educational institutions creates a national competitive advantage for the car industry.
