This study investigated stakeholder groups' perceptions regarding the appropriate level of expenditure for the fulfillment of corporate social responsibility, and surveyed and analyzed the actual expenditures of sample firms on corporate social responsibility. Accordingly, a questionnaire survey was conducted among stakeholder groups to examine their perceptions of the appropriate level of corporate social expenditure, and the actual social expenditure amounts of sample firms were investigated through interviews and on-site visits. The results of this study are as follows. First, the surveyed groups responded that firms should allocate 2.75–3.25% of sales revenue as expenditures for fulfilling social responsibility. This is a higher ratio than the 1.37% found in the 1984 survey conducted by the Federation of Korean Industries (FKI). Among social responsibility categories, the employee relations area showed a relatively higher ratio compared to other areas. Second, the results of investigating the actual social responsibility performance of sample firms revealed that they were spending more on social expenditures than the amount found in the 1984 FKI survey, and the expenditure ratio to sales revenue was also higher than that indicated in the questionnaire survey results of this study. Furthermore, when examining social expenditures by firm size, large firms were spending at a higher ratio than small and medium-sized enterprises, and by functional type, public enterprises were spending at a higher ratio than private enterprises.
