Abstract:
OBJECTIVE:To investigate the rule for circulation system structure of drug market,and to analyze drug circulation costs.METHODS:The rules for macrostructure and microstructure of drug circulation were analyzed.The quantitative conception of circulation links(y),circulation extents(n),last nodes(m) and transaction relations were introduced and their relationship were investigate using mathematic model.The proportions of transaction relation in various sections were adopted to analyze circulation cost.RESULTS:There were rules for macrostructure and microstructure of drug circulation.The microstructure showed as a dendrogram circulation structure.Last nodes(m) and circulation extents(n) determinated circulation links(y),relationship between them was y=lnm/lnn.The proprotion of transaction relations in the last link was much higher than in the middle links.CONCLUTIONS:According to the mathematic model,transaction relations mainly concentrate in the last link.As a result it is not possible for us to cut down the quantity of transaction relations and the circulation costs through compaction of the middle links.
