This text tries to research from the concept of logistics" and it is in our current development condition;" Logistics" is the person whom a the economy that kind is all new operation mode reflect to acculturate the exaltation of the degree; Make use of the mark thinks to develop the three greatest appearances theories concerning the person, to the economic condition of merchandise first the person"s existence appearance of analytical wait three aspects, made the first step investigation to the " logistics" and the persons acculturation degree.

由"物流"这一企业经济运作模式所反映的人类当代生存的"物化"与"社会化"状态只是人类历史发展到一定阶段的产物，随着社会生产的发展，科学技术的进步，人类必将摆脱"物化"这一生存状态而达至人的全面发展。市场经济时代的"物流"实践呈现出科技化及强化人的"物化"倾向的趋势，这些趋势是人的"物质变换"水平提高的表现，但同时也蕴含着破坏人与社会和谐发展的危险因素，需要加以警惕和控制。但是，在人"以物的依赖性为基础的独立性阶段"，只有通过发展"物"的方式才能为人的自我依赖阶段提供坚实的物质基础。
