In the face of intense technical rivalry and economic globalization, sustainable development of the firm is becoming important to many companies. The majority of firms are addressing it strategically. fostering sustainable corporate development, enhancing brand competitiveness, and building a company's reputation all depend on the successful implementation of corporate social responsibility. The degree of corporate governance is also a critical component in the future development of a firm. Thus, the present research employs empirical analysis to achieve the objective of this study, to shed light on whether corporate social responsibility contributes to the sustainable growth of businesses. From the standpoint of corporate governance, it also examines the impact of internal governance elements on the link between both. From 2018 until 2022, the fixed-effects regression test was performed on a sample of shareholding firms listed in the first market in the Amman Stock exchange. The findings indicate that proactive corporate social responsibility may support sustainable development. Moreover, the corporate social responsibility process on sustainable development of the firms is moderated by corporate governance elements including the quality of accounting information, management capabilities, and internal control. There are also limitations to this investigation, such as the study focused on top firms and ignored the other listed firms, while future research can discover other types of firms. Finally, combining corporate social responsibility with corporate governance may increase sustainability, boost competitiveness, and support long-term economic stability, particularly in emerging nations like Jordan that are important for employment and economic growth.
