Once the Romania's EU access, the concept of social responsibility became more and more acquainted by the campaigns of Romania and the population as well. Within this context, campaigns are faced with a new challenge: adopting a responsible behaviour towards community and environment along their activities regarding the business environment. The purpose of our study is to answer the questions related to the Corporate Social Responsibility concept after the European Union accession: (1) How the social responsibility campaigns improved during the economic crisis? (2) Why the local and multinational companies in Romania have adopted the Corporate Social Responsibility practice? (3) What was the influence of these campaigns on community? The research is based on information about eighteen enterprises from Romania, obtained by analysing the specialized sites. Results show that there is a strong relationship between the concepts of the Lisbon Strategy - as social renewal, business competitiveness and sustainable development –and the social responsibility principles. Through this correlation we identified the main reasons why nowadays companies in Romania assume the responsibility on community. However, beside this social responsibility, which is fundamental, the Corporate Social Responsibility concept also means having an ethical behaviour regarding economic activities and respecting the law. This way we can affirm we have now a clear vision of the Corporate Social Responsibility concept, an ample subject regarding social behaviour of enterprises.
