Corporate citizenship is a significant concept of corporate social responsibility and sustainable business. It has also become an important issue in the academic field. Past studies used to discuss the issue of corporate citizenship from the viewpoints of management and marketing. However, these previous studies cannot clarify the structural relationship between the corporation and the society. Therefore, this study adopts the concept of civil society to discuss the meaning of corporate citizenship. Moreover, this study applies the concepts of issue management, social agenda building, and media advocacy to analyze the corporate citizenship activities in civil society. Last, this study chooses a case, 'Keep Walking Fund,' to explain its corporate citizenship practices in terms of the concept of civil society.
