Abstract
The extensive practice of applying social responsibility tools shows that corporate social responsibility determines the sustainable development and competitiveness of a business. However, the mechanism of this influence remains incompletely studied. Currently, there are only fragmentary studies of the impact of business reputation and company image on its value, customer satisfaction, and staff satisfaction. However, such a mechanism has not yet been proposed. This is a gap in modern knowledge. The article proposes a model for the formation of sustainable development of a quasi-public company in the environment of the principles of effective CSR management. The results of the study showed that the algorithm of the CSR management improvement process is the weakest point. However, in general, the lag in the profile of compliance with CSR principles is not critical and amounts to only 26.4%. The overall value of the cognitive matrix for assessing the implementation of the principles of effective CSR management was 132.5.
