毋庸讳言，中国制造业与国外相比有很大的差距， 主要表现在产品性能低、质量差、寿命短，几乎所有的产品都可以一言以蔽之。 以矿山机械中的采掘设备为例，差距不仅仅在数量和品种，更在于设备质量性能和配套程度，８０％处于８０年代中期以前水平，能达到８０年代天９０年代? Needless to say, there is a big gap between China’s manufacturing industry and foreign countries, mainly because of low product performance, poor quality, and short life span. Almost all products can be covered in a word. Taking mining equipment in mining machinery as an example, the gap is not only in quantity and variety, but also in equipment quality performance and supporting degree. 80% is in the level before the mid-1980s. Can it reach the 1980s and 1990s?
