Social responsibility has begun to draw attention in Vietnam in recent years. Corporate Social Responsibility (CSR) is still a very new concept and pioneers, both researchers and practitioners, in this area are facing numerous challenges in executing CSR programs in Vietnam. For the purpose of studying the impact of CSR on the financial performance of the firm, we studied a sample of 30 listed Vietnamese firms in the food industry over the period of 2013-2015. We used archival data as the input data for the quantitative research method to produce regression models and examine the relationship between CSR and corporate financial performance (CFP) in Vietnam. The results show that there is no significant relation between the two factors. On the basis of the findings, some suggestions are made for rational directions to improve the social responsibility of enterprises in Vietnam.
