灰市是指不正当地投市场需求之机,以过高的价格现货成交稀缺商品的市场,灰市价格是指在上述市场上成交的价格。灰市和灰市价格开始出现于第二次世界大战以后的西方国家,当时供货商不能满足战时形成的潜在需求。一方面虽然物价管制已经取消了,但是许多生产者仍然继续将他们的货物配售给他们的老主顾而没有趁机抬高价格。另一方面,某些制造商和中间商则将他们得到的配给物资以三、四倍于他们支付的价格转售出去。因此,灰市和灰市价格产生的前提条件是一种商品物资存在两种不同的供给渠道,不同的渠道有不同的价格。一种是受优待的顾客支付的价格,另一种是不受优待的顾客支付的高得多的价格,即灰市价格。前一种顾客由供货商配售给一定数量的货物,后一种顾客必须到灰市上去搜罗以满足其需要。灰市交易和黑市买卖的区别在于灰市交易虽可能不符合道德标准,但它并不是非法 The grey market refers to the market that improperly invests in market demand, and sells scarce commodities at high prices, and the grey market price refers to the price in the above market. The grey market and grey market prices began to appear in Western countries after the Second World War, when suppliers could not meet the potential needs of wartime formation. On the one hand, although price controls have been eliminated, many producers continue to sell their goods to their regular customers without taking the opportunity to raise prices. On the other hand, some manufacturers and middlemen resell their distribution supplies three or four times the price they paid. Therefore, the precondition for the gray market and grey market price is that there are two different supply channels for a commodity material, and different channels have different prices. One is the price paid by the preferential treatment customers, and the other is the much higher price paid by the preferential treatment customers, namely the gray market price. The former customer is placed by the supplier to a certain amount of goods, and the latter customer must go to the gray market to meet their needs. The difference between a gray market transaction and a black market transaction is that while a gray market transaction may not be ethical, it is not illegal.
