人们常常可以发现,一些物资企业在日常的经营中,尽管能够做到商品品种齐全,质量优异,价格合理,服务良好,但其销售状况和经济效益,有时却不令人满意。例如:A市公司和B市公司是同业公司,A市公司所作的促销努力,远比B市公司强,但却销售平平;某商店的机电产品质次价高,反而比近在咫尺的机电设备公司销售有佳;某采购人员,明知本市有资源,却舍近求远,外地采购,费时费力提高成本等等。由此看来,在物资流通过程中,除资源的品种、质量、价格、服务等影响营销的因素之外,还有其它的制约因素存在。 People can often find that in the day-to-day operations of some material companies, their sales and economic benefits are sometimes unsatisfactory, despite the fact that they have a wide range of goods, excellent quality, reasonable prices and good services. For example: A city company and B city company are fellow companies. A city company’s sales efforts are far stronger than those of B city companies, but they are sold at a mediocre level. The electromechanical products of a store are of high quality, but they are closer to electromechanical Equipment company sales are good; a procurement staff, knowing that the city has resources, but it is close to seeking far, outside procurement, time-consuming and costly to increase costs and so on. From this point of view, in the process of material circulation, in addition to factors such as the variety, quality, price, and service of the resources that affect marketing, there are other constraints.
