摘 要
  世界制造业转移,中国正在逐步成为世界加工厂。美国、德国、韩国等国家已经进入工业化发展的高技术密集时代与微电子时代,钢铁、机械、化工等重工业正逐渐向发展中国家转移。我国目前经济发展已经过了发展初期,正处于重化工业发展中期。
、德国的重化工业发展期延续了18年以上,美国、德国、韩国四国重化工业发展期平均延续了12年,我们估计中国的重化工业发展期将至少延续10年,直到2015年。因此,在未来10年中,随着中国重化工业进程的推进,中国企业规模、产品技术、质量等都将得到大幅提升,国产机械产品国际竞争力增强,逐步替代进口,,机械行业中部分子行业如船舶、铁路、集装箱及集装箱起重机制造等已经受益于国际间的产业转移,并将持续受益;电站设备、工程机械、床等将受益于产业转移,加快出口进程

Abstract
Transfer of world manufacturing, China is gradually becoming the world’s factory. United States, Germany, Korea and other countries have already entered the era of industrialization and the development of microelectronics era of high-tech intensive, steel, machinery, chemicals and other heavy industry is gradually transferred to developing countries. China's current economic development has been the early stages of development, the development of heavy industry is in the middle. ﻫThe next 10 years will be the best period of China’s machinery industry。 United States, the development of heavy chemical industry in Germany more than 18 years of continuity, the United States, Germany, South Korea four countries on average continue the development of heavy chemical industry for 12 years, we estimate that the development of China's heavy chemical industry will continue through at least 10 years, until 2015 . Therefore, in the next 10 years, with China to promote the process of heavy and chemical industries, the Chinese firm size, product technology, quality and so will be significantly improved international competitiveness of domestic machinery products increased, and gradually replace imports and exports accelerate。 Currently, the central molecular machinery industry sectors such as shipbuilding, railway, container
