Bar Codes Lead to Frequent Deliveries and Superstores
研究条形码和计算机库存跟踪等新信息技术对零售最优组织的影响，发现信息技术与频繁送货互补，且采用该技术会增大商店规模，与近年零售业高频送货和大卖场模式的成功一致。
This article explores the consequences of new information technologies, such as bar codes and computer tracking of inventories, for the optimal organization of retail. The first result is that there is a complementarity between the new information technology and frequent deliveries. This is consistent with the recent move in the retail sector toward higher frequency delivery schedules. The second result is that adoption of the crew technology tends to increase store size. This is consistent with recent increases in store size and the success of the superstore model of retail organization. Copyright 2001 by the RAND Corporation.
