Any socio-economic system cannot develop in an environment without competition. Competition drives progress, but to function and develop optimally, an enterprise must have an elevated level of competitiveness. Thus, the chosen topic is relevant. The purpose of this study was to analyse the main methods for assessing the level of competitiveness of an enterprise. The main advantages and disadvantages of the main methods of assessing the level of competitiveness of an enterprise were highlighted. Examples of using SWOT and PEST analysis were presented. It was found that the level of competitiveness of the enterprise should be understood as such a state in which the quality of competitive advantages on the market allows demonstrating a high, medium, or low level of competition. It was also noted that the state of security substantially affects the competitiveness of the enterprise and without effective security mechanisms, high indicators will be problematic to achieve. It was found that competitiveness should be considered as such a level of functional and structural organisation of the enterprise, at which one can discuss the ability to ensure production and sale of products and services at a level sufficient to meet demand and ensure high positions in the market relative to competing producers. The results obtained can be used in the activities of Ukrainian enterprises.
