Introduction Since its publication in 1990, Michael Porter's book "National Competitive Advantage" has gained a lot of attention. The main analysis tool of this book is diamond with a competitive advantage (Figure 1). This model is based on four country-specific "determinants" and two external variables. Porter's four determinants and two external forces interact within the "diamond" of competitive advantage, and the nature of the international competitiveness of the country varies with the type and quality of these interactions.
Porter's Competitive Advantage Diamond provides a useful framework for analyzing the interactions among the L-specific key assets of each country. In addition, his analysis of other factors will affect the extent to which companies adjust their value activities across national borders. Human resources, material resources, knowledge resources, capital resources and infrastructure are all included in the factor condition of the Porter Diamond model, which is important for its competitiveness. Buyers from local markets are pressured to innovate new products and advanced products faster than competitors, and this is called the demand condition of the Porter diamond model. Related industries and supporting industries will provide information to promote innovation, internationalization and cost effectiveness. A solid strategy, structure and competition are the fourth determinants of competitiveness. (Traill and Pitts, 1998)
In 1990, Michael Porter developed his own book "The Competitive Advantage of the Country", a porter diamond also known as a diamond model. The four decision elements of Porter Diamond must function as a system, not as separate systems. It provides an answer "Why does the country achieve international success in a particular industry" (Porter, 1998: 71). Potter 's diamond framework is generally applicable, but many critics think the model is defective. - Diamond diamonds are the most famous gem. It is known as its glow and the hardest mineral on the planet "King of Jewels". (Foa, page 50) That feature serves it for many different purposes. Since diamond is the hardest diamond on the Mohs scale, it provides tools useful for industrial applications such as drilling of hard materials. However, they are very rare, which makes them very valuable. Their beauty and glow make them a perfect choice for jewelry.
