【正文】 ch other and form a tendency of new integration and establish a working research and development center, and the establishment of a system for the transnational corporations39。 global research and development center has quickened the process of this separation. Basing themselves on the new understanding of the epoch of informationization, experts believe that in the process of its march toward a “world factory”, China has the conditions to bee a “dual world factory”the “duality” characteristic has manifested itself: On the one hand, China gives prominent expression to itself in the aspect of the traditional manufacturing industry。 on the other hand, it has experienced rapid development in the manufacturing of information technology and other hightech products. The fact that China has a huge consumer market must not be neglected. It is the view of experts that regions most hopeful to bee the “world factory” are currently the Pearl Rive and the Yangtze River deltas with a concentration of industries。 whereas the core force is nongovernmental and foreign investments. However, in regard to the question of whether or not China is a “world factory” and whether or not it can bee a “world factory”, the conclusion, after all, cannot be drawn through study, discussion or analysis. Just as Wang Zhongming, director of the Information Center of the State Economic and Trade Commission, one of the host units of the recent forum, said in his summary, a “world factory” is the will of our times and the strength of social logic on the development of a kind of history. Whether you want it or not, history invariably and stubbornly express its will, if the world factory is to e, nobody can block it. Many people believed that with more than two decades of market reforms and opening up, China has bee a “world factory”, a title first given by the Japanese Ministry of International Trade and Industry in a white paper and adopted by other countries time and again. However, some argue that China now is only a “world workshop” as the capability of manufacturing sophisticated products in China is not strong and the overall petitiveness is not high. China is still a material processing center instead of a manufacturing center due to the current manufacturing level, particularly the big gap between the level of China39。s manufacturing industries and that of the world39。s advanced, in terms of the overall economic strength, quality and the petitive power of the manufacturing sector, especially proportion of possession of patented core technologies. In fact, much of manufacturing in China is heavily concentrated on labor intensive, simple processing and assembly operations. China today is a vital part of the global supply chain for it is the world39。s largest producer in a range of products including textiles and clothing, telephones, color TVs and microwave ovens. Multinationals have kept establishing procurement centers across China. Shanghai alone is home to procurement anizations founded by many multinationals. The challenge for China now is not just to be a part of the global supply chain, but to move up the value chain as well. China39。s neighboring countries are following with awe and veneration as China is undergoing change into a “world factory” with its unchallenged position on many world markets for manufactured goods Wang Zhongming said creation of a world factory is a historical process as well as a plicated system engineering. Many experts agree that presently China is still not a “world factory”, we need to do many preparations, which involve problems related to property rights, ownership, technological progress, management, and the improvement of laborers39。 qualities. This system project has many tentacles, has extensive connections and involves various aspects, this is also destined that to turn the world factory into a reality in China cannot be acplished at one stroke. 教師評(píng)語(yǔ) 成 績(jī)： 教師簽名： 2021年 3月 12日
