The positive relationship between unique resources and sustainable competitiveness of the company has been well understood and applies to almost all businesses. However, little is known about the specific effects of the uniqueness of resources and business strategies in this relationship. Using resource-based view (RBV), Porter's five-factor theory, and game theory, as well as imitation theory between companies, this study explains how the influence of company-specific resources and the uniqueness of the company's strategy as a sustainable competitive advantage affect performance. Analysis of data collected from surveys on 101 mining companies in Indonesia shows companies with distinctive resources are able to produce unique business strategies and insofar as they cannot be replicated, companies can enjoy sustainable competitive advantage. This implies that mining companies need to avoid their resources and business strategies to be imitated by their competitors if the company still wants to maintain competitive advantage and performance.

Companies that carry out continuous innovation are seen as a source of competitive advantage. In achieving competitive advantage, there are several other things that can be a measure, namely resource excellence, position advantage, and value advantage for customers. The superiority of resources consists of superior expertise and excellence in raw materials as well as marketing and capital performance. The position superiority which consists of relatively low of cost advantages and value advantages for customers is a value that is different from the others and is not easily replaced. In accordance with Porter's opinion, competitive advantage can be obtained from resources and capital, namely the strengths and weaknesses of marketing performance, while capital is defined as the company's ability to manage its resources to work together as a work team in one department, or in other words the high or low performance of marketing will affect the high or low competitive advantage of the company. Position excellence consists of relatively low of cost advantages and value advantages for customers. In a rapidly changing environment, competitive advantage is determined by creativity and innovation that can satisfy customer desires better than competitors. Every company that competes in an industry has a competitive strategy, explicit or implicit. This strategy might be developed explicitly through the planning process or it might also have developed implicitly through the activities of various functional departments of the company.
