Korea companies in China often encounter a series of problems such as Chinese employees frequent job quitting，antipathic to authoritarianism management in Korean companies, mistrust and labor disputes caused by increasing labor disputes and etc. through a deep analysis I found the root to these questions is the cultural differences between China and Korea. Traditional korean culture emphasizes community consciousness, the features of which are authoritarianism, collectivism, and exclusivecronyism. in addition, hierarchical army culture has great impact in Korean society and culture, therefore, Korean companies are featured as collective communities with clear hierarchical employment system. different from korea, as enforcing Communist Party and collapse of feudal Confucianism, hierarchy culture emphasizing differences between gender, age and social level is diminishing, instead, equal consciousness is growing,"everyone is equal" is greatly emphasized in human relations. Korean companies in China needs to get rid of Korean-centered thinking mode and rethink more about Korean way of management, which means to improve parental authoritarian management and use "democratic" management fitting Chinese present situation. creating equal working environment and enhancing democratic communication is important in decreasing cultural differences and increasing humane trust. therefore effective human resources management can be realized.
