摘 要: 根據(jù)規(guī)模經(jīng)濟(jì)的原理， 對3種確定最小經(jīng)濟(jì)規(guī)模（MES）的方法進(jìn)行了分析和比較， 并運(yùn)用這些方法對我國鉛鋅冶煉行業(yè)進(jìn)行MES估算， 得出鉛冶煉企業(yè)MES為4萬t/a， 鋅冶煉企業(yè)MES為7.4萬t/a。 采用3個實(shí)物指標(biāo)， 對我國24個鉛鋅冶煉企業(yè)進(jìn)行研究， 評估我國鉛鋅冶煉產(chǎn)業(yè)規(guī)模經(jīng)濟(jì)水平。 結(jié)果表明企業(yè)平均規(guī)模與經(jīng)濟(jì)規(guī)模的比值， 鉛冶煉為38.1％， 鋅冶煉為39％， 企業(yè)平均規(guī)模顯著偏小； MES企業(yè)產(chǎn)量占全部產(chǎn)量的比例， 鉛冶煉為49.3％， 鋅冶煉為53.2％， ＭＥＳ企業(yè)產(chǎn)量占全部產(chǎn)量的份額不高； 分散生產(chǎn)經(jīng)營狀態(tài)較嚴(yán)重， 且全部企業(yè)開工率偏低， 在80％左右， 鉛鋅生產(chǎn)能力過剩， 缺乏市場競爭能力。 由此， 可以看出我國鉛鋅冶煉產(chǎn)業(yè)規(guī)模經(jīng)濟(jì)水平較低。 所以， 提高我國鉛鋅冶煉企業(yè)經(jīng)濟(jì)規(guī)模， 增強(qiáng)市場競爭力是提高經(jīng)濟(jì)效益的一個重要問題。

Abstract: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 40000 t/a, and that of Zn is 74000 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.
Key words: Pb and Zn metallurgy industry economies of scale MES
