分析师认为，部分钢厂采取限价措施，主要是为了稳定市场，但这种限价措施不会对市场有太大的影响。

“目前经销商也想涨价，但涨价之后他们的货销售不出去，在供大于求的情况下没有经销商愿意囤货。限价措施只能在短期内稳定价格，市场终究还是要回归基本面。”分析师说。

光大期货矿钢研究员夏君彦表示，在钢材市场“金九”旺季不旺、下游需求疲弱的情况下，限价措施实际效果不大。不过，钢厂再度限价说明生产亏损比较严重，限价也是无奈之举。

据了解，目前采取限价措施的主要是北方的一些钢厂。“现在北京的钢材价格太低了，钢厂生产钢材每吨要亏损150元。”夏君彦告诉记者。

多位行业人士在接受记者采访时均表示，由于目前正处于第三季度末期，钢企普遍面临还贷压力，资金状况堪忧，对后期的市场也缺乏信心。

一位钢铁行业资深人士表示，国内钢铁需求全面下滑才刚开始，制造业的“寒冬”将使国内钢铁企业的日子更加难过。钢企的资金状况还会持续恶化，随时可能出现大面积停产，这还会对铁矿石需求造成冲击。

Analysts believe that part of the steel mills to take the limit measures, mainly in order to stabilize the market, but this limit will not have a big impact on the market.
"At present, dealers also want to rise in price, but after the price of the goods they sell do not go out, under the situation of oversupply of no dealers willing to hoard goods. Limit price measures can only be in a short period of stable prices, the market will eventually return to the fundamentals." Analysts say.
Xia Junyan, said China Everbright futures steel researcher, in the steel market, Kim Gu season is not prosperous, weak downstream demand, the actual effect is not limited to the actual effect. However, the steel mills to limit the production of a more serious loss is more serious, the price is also helpless.
It is understood that the current price fixing measures are mainly some steel mills in the north. "Now Beijing's steel prices are too low, steel production of steel per ton to a loss of 150 yuan." Xia Junyan told reporters.
Many industry insiders said in an interview with reporters, due to the current is in the end of the third quarter, steel prices are generally faced with the pressure on the loan, the situation is worrying, the market is also a lack of confidence in the late.
A steel industry veteran said that the domestic steel demand has just begun to decline, the manufacturing industry's winter will make the domestic steel enterprises more difficult days. Steel prices will continue to deteriorate the situation of funds, at any time may occur in a large area, which will also impact on the demand for iron ore.
