금융위기 이후 원가관리 실무의 변화와 적절성:한-일 간의 비교

This study explores and compares changes in cost management practices by companies in Korea and Japan in response to demand changes and strategic direction changes therein subsequent to the global financial crisis in 2008. The study aims to provide an empirical evidence as to how properly companies meet the environmental changes in terms of cost management. Regression analyses of cost stickiness are employed to compare and evaluate how differently sales change rates explain the cost change rates between the pre and post crisis periods in the two countries. Japanese companies experienced substantial reductions in demands after the crisis. On the other hand, Korean companies maintained high levels of demands with slight reductions in demand growth. We analyzed whether changes in the cost management practices in each country are commensurate with the demand changes in that country by dividing companies into sales increase group and decrease group. The results show that Korean companies increase their input levels in various cost items and exhibit more stickiness in costs, which are consistent with relatively higher demand levels in the post period. On the other hand, Japanese companies show their cost management efforts to adapt to reduced demands after the crisis. The empirical findings of the current study can be interpreted as an evidence that cost management practices by companies in both countries are consistent with their demand and strategic changes.
