class="khcont">　　合計獲利340億美元(約合2176億元)。而根據(jù)中國鋼鐵工業(yè)統(tǒng)計，同期國內(nèi)重點鋼鐵企業(yè)僅實現(xiàn)利潤564億元，前者是后者近4倍。由于全球鐵礦石市場呈壟斷局面，近年來業(yè)界一直有“礦山吃肉、鋼廠喝湯”說法。　　以2010年為例，三大礦山合計實現(xiàn)凈利480億美元，是中國鋼鐵業(yè)盈利5倍。如今，這一極端不均衡局面非但沒有被糾正，反而進(jìn)一步加劇了。知名鋼鐵現(xiàn)貨交易平臺“西本新干線”總經(jīng)理助理盛志誠認(rèn)為，下半年鋼鐵行業(yè)形勢，可以兩句話形容：一是產(chǎn)量增速可能進(jìn)一步放緩。　　今年7月份粗鋼日均產(chǎn)量，已較6月環(huán)比下滑5%。二是困難大于上半年。中鋼協(xié)指，雖然下半年保障房和水利建設(shè)會提振鋼材需求，但造船、汽車等行業(yè)增長趨緩以及受阻，將部分抵消這一因素。再加上生產(chǎn)成本、資金成本居高不下，行業(yè)降本。　　第四季度精密鋼管需求端大概率回暖面對無錫精密鋼管廠全行業(yè)產(chǎn)能過剩，采取了多項措施，對珩磨精密鋼管企提了減產(chǎn)、限產(chǎn)甚至停產(chǎn)要求。并進(jìn)一步建立健全淘汰退機(jī)制，通過控制產(chǎn)能，關(guān)閉部分中小珩磨精密鋼管礦，對違規(guī)珩磨精密鋼管加大治理力度，讓優(yōu)質(zhì)珩磨精密鋼管企有更廣闊發(fā)展空間。
