Abstract
In recent years, the concept of sustainable development of the company occupies an increasingly large place, both in theoretical research and in practice. The idea does not imply a fixed state of harmony, but a progressive goal that directs company development and management to change the exploitation of resources, technologies, institutions and investments. The new challenges pose a number of questions - what motivates the owner, the manager in this direction, what is the relationship between sustainable development and long-term success in business (building competitive advantages); what are the factors that determine the choice of a sustainable strategy in the company. This determines the purpose of the research - to analyze the relationship between the sustainable development of the company and the building of competitive advantages, which is mediated by the company strategy, a function of market and company characteristics.
