2、化工業(yè)發(fā)展期將至少延續(xù)10年,直到2015年。因此,在未來10年中,隨著中國重化工業(yè)進(jìn)程的推進(jìn),中國企業(yè)規(guī)模、產(chǎn)品技術(shù)、質(zhì)量等都將得到大幅提升,國產(chǎn)機械產(chǎn)品國際競爭力增強,逐步替代進(jìn)口,并加速出口。目前,機械行業(yè)中部分子行業(yè)如船舶、鐵路、集裝箱及集裝箱起重機制造等已經(jīng)受益于國際間的產(chǎn)業(yè)轉(zhuǎn)移,并將持續(xù)受益;電站設(shè)備、工程機械、床等將受益于產(chǎn)業(yè)轉(zhuǎn)移,加快出口進(jìn)程關(guān)鍵詞:數(shù)控工業(yè)化發(fā)展刀具機床AbstractTransferofworldmanufacturing,Chinaisgraduallybecomingtheworld'sfactory.UnitedState
