This study investigated the relationship between the change in corporate social performance and financial performance in Taiwan. According to stakeholder theory, financial performance should be improved, no matter by diminishing cost, increasing competitive advantage, or elevating operative efficiency, when firms satisfy the demands of multiple stakeholders. Through the finding of this empirical research, the change in corporate social performance was positively related to change in return on sales and growth in sales at the same year, indicating that improvement of corporate social performance may lead to improvement of financial performance in the short-term.
