There has been much theoretical debate on issues of business ethics during the last decades, but there has been little research which could concretise the content of these issues in terms of practical business. Although business life must frequently deal with concepts such as corporate social performance, business ethics and the acceptability of operations, the content and meaning of these concepts has remained flexible. In addition, rapid internationalisation and globalisation have introduced a number of new phenomena related to corporate social performance. An attempt at defining the concepts more precisely and searching for a potential indicator was considered necessary in order to concretise the business environment facing corporations engaged in internationalisation and globalisation. The connection between corporate social performance and stakeholder theory provides a basis for the proposal put forward here that acceptability of operation could be employed as an indicator of corporate social performance. This approach was then applied to developing a model which could be used to assess corporate social performance.
