Corporate Social Responsibility (CSR) is a concept suggesting that good business is about more than maximizing profit. In order to achieve social legitimacy a corporation must pay attention to a complex web of values and relations, and different CSR strategies and policies can be viewed as ways to manage this complexity. The corporate legitimacy matrix introduced in this article represents the strive for social legitimacy as a balancing act along three lines: a) The sustainability dimension: Balancing economic, social and environmental (...) considerations, b) The stakeholder dimension: Balancing considerations of stakeholders at the local, national and global level, and c) The trust dimension: Balancing rational argumentation, credibility and emotional appeal. This article explores these three aspects of corporate legitimacy and how they are related. It is intended as a theoretical contribution towards a better understanding of the relationship between CSR and corporate legitimacy, as well as a practical tool to support the analysis of actual corporate legitimacy challenges.
