Porter's Diamond Model is a strategic economic theory that seeks to understand why some nations become competitive in particular industries and others do not. Developed by Michael Porter, a professor at Harvard Business School, the model is a tool for analyzing the competitive advantage of nations, regions, or cities. It is based on four attributes of a nation that shape the environment in which local firms compete, and these attributes promote or impede the creation of competitive advantage.
We've interviewed dozens of senior Strategy & Operations leaders to hear how they've built and scaled the function at their high-performing organizations.

The model has been widely used in economic geography and strategic management, among other fields. It has also been used to analyze the competitive advantage of nations in international trade and to understand the competitive dynamics of global industries. Despite its widespread use, the model has also been criticized for its lack of consideration of the global business environment and the role of multinational corporations.
The Diamond Model is based on four interlinked attributes, or determinants, that create an environment in which companies can become nationally competitive. These determinants are: Factor Conditions, Demand Conditions, Related and Supporting Industries, and Firm Strategy, Structure, and Rivalry. Each of these determinants is influenced by chance events and government, which are also part of the model.
Understanding these determinants can help companies and policymakers to identify the sources of competitive advantage and to formulate strategies that leverage these advantages. The determinants are not static, but change over time as a result of economic development and technological progress. Therefore, the model is dynamic and can be used to analyze the evolution of industries and nations over time.
Factor conditions refer to the inputs necessary for competitive advantage. These include human resources, physical resources, knowledge resources, capital resources, and infrastructure. Specialized factors, which are more specific and specialized for particular industries, are more important for competitive advantage than general factors, which are basic inputs that can be obtained by any company.
Factor conditions are not static, but can be created or improved by investment and effort. For example, a country can invest in education and training to improve its human resources, or in research and development to create new knowledge. Therefore, the model emphasizes the role of investment in creating and maintaining competitive advantage.
Demand conditions refer to the nature of home demand for an industry's product or service. Strong, sophisticated, and demanding customers can pressure companies to innovate and improve. Home demand is particularly important for industries that are sensitive to user needs, such as consumer electronics or fashion.
Home demand can also create advantages in global markets if it anticipates or shapes global demand. For example, a country with high environmental awareness and strict environmental regulations can create a competitive advantage for its clean technology industry in global markets.
Related and supporting industries refer to the presence or absence in the nation of supplier industries and related industries that are internationally competitive. Having access to capable, locally based suppliers and related industries can increase efficiency and facilitate innovation. It can also create advantages in terms of coordination, problem solving, and knowledge sharing.
Related industries can also create advantages through clustering, which is the geographic concentration of interconnected companies and institutions in a particular field. Clusters can increase productivity, drive innovation, and stimulate new businesses.
Firm strategy, structure, and rivalry refer to the conditions in the nation that determine how companies are created, organized, and managed, and the nature of domestic rivalry. Different nations are characterized by different management ideologies, which can either help or hurt the ability of firms to innovate or to build a competitive advantage.
Intense domestic rivalry can stimulate innovation and improvement, and can result in a competitive advantage in global markets. Domestic rivalry can be influenced by factors such as corporate governance, labor relations, and capital markets.
In addition to the four determinants, the Diamond Model also includes two additional variables: chance and government. Chance events are occurrences that are outside of the control of firms and that can disrupt the national diamond. These can include technological breakthroughs, political changes, or natural disasters.
Government can influence each of the four determinants through policies and regulations. It can also influence the national diamond directly by coordinating activities, stimulating demand, or promoting change. However, the role of government in the model is complex and can be both positive and negative.
The Diamond Model has been widely used in strategic management and economic geography to analyze the competitive advantage of nations, regions, or cities. It has also been used to understand the competitive dynamics of global industries, and to formulate business and policy strategies.
Despite its widespread use, the model has also been criticized for its lack of consideration of the global business environment and the role of multinational corporations. Some critics argue that the model is too static and does not consider the dynamic nature of international business. Others argue that the model is too nationalistic and does not consider the role of global strategies and global market forces.
In strategic management, the Diamond Model can be used to analyze the competitive position of a firm in a global industry. It can help to identify the sources of competitive advantage and to formulate strategies that leverage these advantages. The model can also be used to analyze the impact of location on the competitive advantage of a firm.
The model can also be used to analyze the competitive dynamics of global industries. By comparing the national diamonds of different countries, it is possible to understand the relative strengths and weaknesses of different countries in a global industry. This can help to identify opportunities and threats, and to formulate competitive strategies.
In economic geography, the Diamond Model can be used to analyze the competitive advantage of regions or cities. It can help to identify the sources of competitive advantage and to formulate strategies that leverage these advantages. The model can also be used to analyze the impact of location on the competitive advantage of a region or city.
The model can also be used to analyze the competitive dynamics of regional or urban economies. By comparing the regional or urban diamonds of different regions or cities, it is possible to understand the relative strengths and weaknesses of different regions or cities in a regional or urban economy. This can help to identify opportunities and threats, and to formulate regional or urban development strategies.
Despite its widespread use, the Diamond Model has also been criticized for its lack of consideration of the global business environment and the role of multinational corporations. Some critics argue that the model is too static and does not consider the dynamic nature of international business. Others argue that the model is too nationalistic and does not consider the role of global strategies and global market forces.
Another criticism is that the model is too deterministic and does not consider the role of managerial decision-making and strategic choice. Some critics argue that the model overemphasizes the role of national factors and underemphasizes the role of firm-specific factors in creating competitive advantage.
Despite these criticisms, Porter's Diamond Model remains a powerful tool for understanding the competitive advantage of nations, regions, or cities. It provides a framework for analyzing the sources of competitive advantage and for formulating strategies that leverage these advantages. However, like all models, it should be used with caution and should be complemented with other tools and perspectives.
In conclusion, Porter's Diamond Model is a strategic economic theory that seeks to understand why some nations become competitive in particular industries and others do not. It is based on four attributes of a nation that shape the environment in which local firms compete, and these attributes promote or impede the creation of competitive advantage. The model has been widely used in economic geography and strategic management, among other fields, but it has also been criticized for its lack of consideration of the global business environment and the role of multinational corporations.
