德国有一家服装厂,每年生产许多手套在附近城市销售,销量一直很平稳。有一年,他们得知不远的地方新建了一家专门生产手套的小工厂,由于这个小厂业务量不大,对他们似乎没什么影响,服装厂也就没太在意。但是,一年后,他们发现：自己生产的手套在市场上不吃香了,而那个小厂生产的手套几乎占领了80％的市场份额…… There is a garment factory in Germany, which produces many gloves every year and sells it in the nearby cities. The sales volume has been very steady. One year after they learned that a small factory specialized in the production of gloves was built not far from the factory, the garment factory did not care too much because it did not seem to have much impact on the small factory. However, a year later, they discovered that the gloves they produced were not popular in the market, while the gloves produced by that small factory occupied almost 80% of the market.
