The overall influential power of China development on international community was misunderstood. What we see is the role of ＂China Factor＂ in different fields. In the process of economic globalization, what economic system of capitalist market has seen is ＂China＇s cheap labor＂, ＂China＇s loose economic system environment＂, ＂earlier abuse of unlimited resource environment＂, ＂China＇s broad consumption market＂ and ＂demographic dividend＂. In global or Asian financial crisis, what other countries valued was China＇s ＂foreign currency＂ accumulated over the years. In global gov- ernance or crisis management, what international community expected was ＂China＇s obligations and responsibilities＂ without the right of speech, etc.. All these are the ＂passive＂ roles produced by ＂a single factor＂ in definite fields. The active and initiative role China will play in international community still needs time and the continuous efforts of several generations. China once was a big country that had significant inftuential power on the world, and China＇s renaissance is a normal process of development of things. What excessive talks about its influential power reflect may be the lack of China＇s influence.展开更多
