“…According to the legitimacy theory, only when an organization's behavior meets the expectations of society and can be accepted by stakeholders can it obtain legitimacy, so as to help the enterprise enjoy a good reputation among the public and attract more investors to support the development of the enterprise (Yu, 2020). The main assumption of the legitimacy theory is that organizations achieve recognition of their goals by fulfilling social contracts, that is, enterprises accept the conditions put forward by the society, undertake social responsibilities to gain acceptance and better understanding, and realize the understanding between society and enterprises, essentially for the purposes of legitimacy, harmonious coexistence, and mutual benefit (Ogunode, 2022).
