The graduate thesis examines the theoretical and practical point of view of corporate social responsibility. In the theoretical part of the work, I’ve investigated and described the concept of corporate social responsibility, its history, key factors, benefits, criticism, the main areas of work, its appearance and promotion in Croatia and the implementation of corporate social responsibility in the banking sector. During the research and writing of theoretical part of work, I used all the available scientific and technical literature. Through the empirical part of the work, I explored whether banks in Croatia apply the concept of corporate social responsibility, to what extent they apply it, in which part they invest most, who is in charge of socially responsible business within the bank and if they are planning further investments in the development of corporate social responsibility. The study was conducted via an online questionnaire and by using the method of content analyzing. By using the method of content analyzation, I analyzed banks' web pages. The study was conducted on a sample of ten banks, and the study includes all types of banks, from large, medium, to small ones. The results show that there are many banks who are referred to as socially responsible, even though in reality they are not. They use CSR as a marketing gimmick. Banks often emphasize donations as the main or only part of social responsibility, although they are only a small part of social responsibility. The paper contributes to a better understanding of the concept of socially responsible business and its practical application in Croatian banks.
