中文摘要：

运用企业资源理论在竞争优势方面的研究成果及作者以往的研究，提出供应链竞争优势来源的租金贡献分析与评价方法．文章首先概括了资源理论对竞争优势问题的解释，以及作者在供应链资源观模型构建，供应链上下游成员在交易价格与变动成本之间存在的传递关系等方面进行的研究．随后，提出成员企业租金贡献的概念，并给出成员企业租金贡献和供应链竞争优势的相应表述，由此认为供应链竞争优势来源于各个成员企业的租金贡献，但不是它们的简单加和，而是通过水平结构上的依次传递，逐步汇集到供应链最终成员企业而形成的．最后，文章给出供应链竞争优势来源的租金贡献评价方法的模拟评价，说明了该方法在供应链竞争优势分析、供应链构建、成员企业选择与评价等方面的应用．

英文摘要：

Using the research work of The Resource-Based View （RBV） theory, combining our former study, this paper pus forward the rent contribution analyzing and appraising method of supply chain competition advantage source. First, this paper sums up the main achievements in the RBV in competition advantage explaining, our study of supply chain model in RBV and the transfer relationship between trade price and variable cost among chain partners. Then this paper brings forward the definition and formula of partner rent contribution and presents the supply chain competition in this way. Based on these, this paper considers that the supply chain competitive advantage is composed of partners＇ rent contributions, and it is not the simply parallel summation of those contributions, but rather the transferring of those contributions one partner after another and gathering to the final partners that form the supply chain competitive advantage. Finally, this paper provides the rent contribution method and gives a simulation to appraise and explain the usage of this method in supply chain competition analyzing, supply chain construction, partner selection and evaluation.
