Corporate Social Responsibility (CSR) Paradigm in its extended form is defined as a complex strategy encompassing four kinds of responsibility: economic one − understood as imperative of financial gain; legal one − obliging to follow the rule of law; ethical one − introducing moral limits of any activity; voluntary philanthropic responsibility − which is displayed by voluntary charitable and welfare expenses. Studies concerning relations between public, private and social (NGO concerning) sector are of great theoretical and practical importance. They require interdisciplinary approach combining common efforts of representatives of legal and economical sciences, social philosophy, ethics, sociology and political science. Corporate Social Responsibility Paradigm is a subject of many controversies. One may distinguish two radical mainstreams of the discussions: conservative and reformist. Conservative mainstream bases on liberal fundaments, criticizes corporate social expenses, identifies corporate social responsibility as an obligation to follow free market rules. Reformist mainstream opts for corporate involvement in solving social problems and natural environment protection.
