This study empirically compared management behaviors of Japanese subsidiaries in Korea with those of subsidiaries from other countries using mail survey data. Japanese subsidiaries showed a general tendency toward localization in various aspects. First, they source(ratio of locally sourced input) and produce(ratio of locally produced sales) more locally than other foreign subsidiaries in the Korean market. They also showed a lower(higher) level of standardization(local adaptation) in marketing strategies. Between the bipolar points of `sticks to general Korean practices` and `sticks to Headquarters` practices` regarding management practices in Korea, Japanese subsidiaries are closer to the former, while the other subsidiaries are closer to the latter. Similar patterns also appear in the decision making location, which means Japanese subsidiaries tend to make decisions more locally at the subsidiary level. All these findings were reconfirmed in the regression analyses controlling for the equity ratio, which implies that higher localization level of Japanese subsidiaries is not just a result of their lower equity ratios.
