近几年来,随着计划经济向市场经济转换,商品经济逐渐繁荣起来,由于市场经济刚刚起步,在体制上还有很多不健全之处,许多商品处于好坏兼有、优劣共存的现象。在众多商品中,农机配件更是如此,据国家有关部门抽样调查表明,农机配件平均合格率在20％左右,大量伪劣农机配件充斥着农机市场。 In recent years, with the transition from a planned economy to a market economy, the commodity economy has gradually prospered. Since the market economy has just begun, there are still many imperfections in the system, and many commodities are in good and bad conditions and have advantages and disadvantages. Among many commodities, agricultural machinery and accessories are even more so. According to the sample survey conducted by the relevant state agencies, the average qualified rate of agricultural machinery parts is about 20%, and a large number of fake and inferior agricultural machinery accessories are flooding the agricultural machinery market.
