The management paradigm shifted to ESG as the atmosphere demanding corporate social responsibility and the disclosure of ESG information became compulsory step by step. This study presents the family business formation activities of Gyeongju Choi's family as an example of ESG management and modernizes the management strategy and management policy. Gyeongju Choi's Family Business Formation Activities First, Choi's family carried out environmental conservation activities such as resource conservation, elimination of wasteful factors, and resource recycling. Second, he did not own more than 10,000 kuk of property, did not buy land in bad years, helped the poor in 100 li in all directions, and finally fulfilled his corporate social responsibility by donating all his property to society and the country. Third, labor-management conflicts were eradicated by not placing barms as part of corporate governance improvement activities, and tenant farmers were able to become self-reliant by pursuing only appropriate profits. In addition, from the perspective of a modern company, he respected the values of shareholders, employees, and customers, and maintained political neutrality by looking at the past but not serving as a government official. The management policy according to the modern management strategy and management strategy for the ESG management activities of Gyeongju Choi's family is as follows. First, the environment-friendly strategy achieves a circular economy that uses resources efficiently through resource saving and resource circulation. Second, the social responsibility strategy recognizes companies as members of the local community and strives for the survival and prosperity of the country by coexisting with the local community through social service, charity, and stable job creation. Third, the governance strategy maintains political neutrality by competing fairly according to laws and ethics, respecting customers, shareholders, and employees, and not using all corporate resources for political purposes. This study presents a traditional and exemplary case of ESG management and will be used as an example in which a family business can be succeeded without objection from members of society in Korea, which lacks long-lived companies. In addition, it suggests that the authenticity of CSR activities is strengthened when social responsibility is implemented horizontally and comprehensively, rather than step by step, as in the model of Carroll (1991), suggesting that all four responsibilities are due.
