Corporate Social Responsibility is a concept according to which enterprises voluntarily take social interests and environment protection as well as relations with diverse stakeholder groups into account at the stage of building their strategies. Indicating benefits to enterprises from implementation of the concept of Corporate Social Responsibility is the objective of this paper. Results of the authors' survey of 106 enterprises operating in the Mazovian region are compared to these of a national survey commissioned by the Polish Agency for Enterprise Development. They serve to demonstrate application of CSR is in direct proportion to size of a business. In addition, respondents designated improvement of company image as the key external benefit and perception of an enterprise as an attractive employer as the major internal benefit. Results of the authors' research in the region of Mazovia and of the national-wide survey show a marked similarity.(original abstract)
