In this study, using field data such as ESG, employee satisfaction, and customer satisfaction data collected from a wide range of industries, the ESG activities of companies and individual activities have an integrated study on the relationship between internal and external customer satisfaction from the perspective of internal and external customers.
The analysis results are as follows. First, through text mining analysis, it was confirmed that there is a relationship between ESG activities and internal and external customer satisfaction. Second, as a result of conducting empirical analysis using field data such as KCGS’s ESG rating, Job Planet’s employee satisfaction, and KMAC’s KCSI data, ESG activities have a positive effect on both internal and external customer satisfaction. In particular, ESG activities were found to have a relatively greater impact on customer satisfaction than employee satisfaction. Third, in the empirical analysis using KEJI, it was found that environmental activities have a positive effect on both internal and external customer satisfaction. Corporate governance activities had a positive effect only on employee satisfaction. Social activities did not have a significant effect on employee satisfaction, but rather showed a negative relationship with customer satisfaction. The interpretations of these findings and the implications are also discussed.
