智慧是经验之女。1930年8月,美国人迈克尔·库仑在纽约州依靠贷款开设了全球第一家理论上的超级市场,也就是后来的超市鼻祖——金库仑联合商店。他根据自己几十年的食品经营经验,精确设计了低价策略,并首创按商品品种特别定价方法。它的超级市场平均毛利率只有9%,这和当时美国一般商店25-40%的毛利率相比,实在是低的令人吃惊。 Wisdom is the daughter of experience. In August 1930, the American Michael Coulomb relied on loans to set up the world’s first theoretical supermarket in the State of New York, which was later known as the cousin of the Supermarket, the Coulomb-Column Store. Based on his decades of experience in food operations, he has accurately designed low-cost strategies and pioneered special pricing methods for commodity varieties. Its average gross profit margin for supermarkets is only 9%, which is surprisingly low compared with the 25-40% gross margin of US general stores at the time.
