对山东淄博市这样一个老工业城市来说,改革、发展的难点挺多。这个市工业最突出的特点是“四多一低”。 “四多”,即国有企业多——全市国有经济占整个经济比重的70％以上;老企业多——区县属以上企业厂龄在40年以上的占60％;大企业多——全市大型企业占市属以上企业的50％;困难企业多——市属以上企业亏损面高达50％。 To an old industrial city like Zibo in Shandong Province, there are quite a few difficulties in reform and development. The city’s most prominent feature of the industry is “more than four low.” More than four state-owned enterprises, ie, the state-owned economy in the city accounts for more than 70% of the total economy; the old enterprises with more than 60% of the factory-owned enterprises in the districts and counties over 40 years old; the large enterprises Large enterprises accounted for more than 50% of municipal enterprises above; difficult enterprises - municipal enterprises above loss-making up to 50%.
