A correct setting method of minimum efficient scale (MES) was obtained by using the accounting method, the survivor technique and the engineering technique according to the practice of Pb and Zn metallurgy industry in China. The results showed that the MES of Pb metallurgy industry is 40 000 t/a, and that of Zn is 74 000 t/a, the economies of scale level of the Pb and Zn metallurgy industry is rather low comparing with the same line abroad. So it concluded that it is important to increase the economies of scale...

A correct setting method of minimum efficient scale (MES) was obtained by using the accounting method, the survivor technique and the engineering technique according to the practice of Pb and Zn metallurgy industry in China. The results showed that the MES of Pb metallurgy industry is 40 000 t/a, and that of Zn is 74 000 t/a, the economies of scale level of the Pb and Zn metallurgy industry is rather low comparing with the same line abroad. So it concluded that it is important to increase the economies of scale level to make the Pb and Zn metallungy industry in our country be more competitive and profitable.

根据规模经济的原理,对3种确定最小经济规模(MES)的方法进行了分析和比较,并运用这些方法对我国铅锌冶炼行业进行MES估算,得出铅冶炼企业MES为4万t/a,锌冶炼企业MES为7.4万t/a。采用3个实物指标,对我国24个铅锌冶炼企业进行研究,评估我国铅锌冶炼产业规模经济水平。结果表明企业平均规模与经济规模的比值,铅冶炼为38.1%,锌冶炼为39%,企业平均规模显著偏小;MES企业产量占全部产量的比例,铅冶炼为49.3%,锌冶炼为53.2%,MES企业产量占全部产量的份额不高;分散生产经营状态较严重,且全部企业开工率偏低,在80%左右,铅锌生产能力过剩,缺乏市场竞争能力。由此,可以看出我国铅锌冶炼产业规模经济水平较低。所以,提高我国铅锌冶炼企业经济规模,增强市场竞争力是提高经济效益的一个重要问题。

Since Zhuzhou smelter estabilished before fourty years,it has expanded lead /zinc production,also has raised success ively technology and economy guideline through the reconstruction and improvement of lead /zinc technolog y.In addition,the author introduces Zhuzhou smelter' s achievement in comprehensive exploitation on re source and the development of new pro ducts and deeply -producting,and also envisions Zhuzhou smelter' s future during“The Fifteen”.

The world output of lead concentrates was somewhat decreased in2001and the market prices were on the slide,and the world zinc ingot output was sustainly increased with result of over supply of world zinc market.And domestic output of lead/zinc was on the sustained increase in2001.Although domestic inventory of refined lead was increased with the decrease of its consumption,the lead acid storage cells exports were increased by a big margin.The situation of domestic zinc market had been serious with its price...

The world output of lead concentrates was somewhat decreased in2001and the market prices were on the slide,and the world zinc ingot output was sustainly increased with result of over supply of world zinc market.And domestic output of lead/zinc was on the sustained increase in2001.Although domestic inventory of refined lead was increased with the decrease of its consumption,the lead acid storage cells exports were increased by a big margin.The situation of domestic zinc market had been serious with its price dropped by a big margin.On the other hand the lead price in2002is predicted to bottom out and strongly bounce upwards,and the zinc price in2002is predicted to recover with its price increased by a small margin.

2001年,全球铅精矿产量有所减少,但价格下滑,锌锭产量持续增长,导致供应过剩、价格大幅下跌。然而,国内铅锌生产继续保持增长。虽然精炼铅的进口量下降,库存增加但由于铅酸蓄电池出口量大幅增加,从而支持了国内铅价的平稳。国内锌市场形势严峻,锌价大幅下跌。2002年铅价有望走出低谷,出现强劲反弹,锌价则有望小幅回升。
