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。
　　未来10年将是中国机械行业发展最佳时期。美国、德国的重化工业发展期延续了18年以上，美均延续了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2020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，并加速出口。目前，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。
Pick to
World manufacturing transfer, China is becoming the world factory. The United States, Germany, South Korea and other countries have entered industrialization development high technology intensive era and microelectronics era, steel, machinery, chemical and other heavy industry is gradually transferred to developing countries. Our current economic development has been the development initial period is in heavy industry development mid-term.
The next 10 years will be China machinery industry development is the best period. The United States, Germany's heavy industry development lasted 18 years, America, Germany, Korea four developing heavy industry average lasted for 12 years, we estimate that
China would at least continue developing heavy industry, 10 years, until 2020. Therefore, in the next 10 years, along with the advancement of heavy industry of China, China enterprise scale, product technical, quality, etc will have boosted, domestic mechanical product enhancement, the international competitiveness, and accelerate gradually replace imported export. At present, the machinery industry molecular industries such as ships, central railway, container and container crane manufacturing has benefited from the international industrial transfer between, and will continue to benefit; Power station equipment, engineering machinery, bed etc will benefit from the industrial trans
