| 摘 要： | 基于经济学演化范式的观点和产业的复杂适应系统特征，构建了以目标产业为核心的产业供求关系网络分析框架。在回顾以往产业集中度与利润率关系的研究成果的基础上，利用国内消费类产业集中度与毛利率的相关系数分析，对以往研究结论做了进一步印证。在此基础上，基于对产业供求关系网络的认识，提出将产业集中度与产业盈利水平关系的研究，从目标产业本身扩展到与其密切相关的上下游产业，深入分析产业间集中度差异对产业盈利水平产生的影响。

| Abstract: | This paper,base on the viewpoint of evolutionary paradigms in economics and the industrial CAS(Complex Adaptive System)characters,a analytical furame of the industrial supply and demand network was founded,to look back on the previous works of scholars in the relation between industrial concentration and profit margin.The previous conclusion was verified by the correlativity analysis between concentration level and gross profit of the Chinese consumption industries.On this base,according as understanding of the industrial supplys and demand network,the correlativity research between concentration level and gross profit level was expanded from a target industry to interrelated industries in the supply and deman network.The influence upon industrian profit level which is made by difference of concentration level between interrelated industries was analyzed by the influence upon price. |
