中文摘要：

在对供应链运作柔性相关研究的评述基础上，区分物流分销柔性和需求管理柔性两个维度。收集有关制造商柔性和绩效的212份有效问卷，验证需求管理柔性在物流分销柔性与关系满意度之间的中介作用，利用以调节回归分析和有条件的非线性回归模型为基础的调节路径分析，深入、全面地探讨环境不确定性在这一中介关系中的调节作用。研究结果表明，在不确定的环境中，物流分销柔性对关系满意度的直接作用更强；在稳定的环境中，需求管理柔性对关系满意度的直接作用更强；物流分销柔性对关系满意度的总作用不受外部环境影响。因此，同时提高两种柔性显然会提高关系满意度，但是单独调整其中任意一种柔性都要首先考虑外部环境。

英文摘要：

Based on the literature review on supply chain operation flexibility , this study distinguishes two dimensions , i.e.phys-ical distribution flexibility and demand management flexibility .Collecting 212 valid questionnaires on manufacturers′flexibility and performance , we test the mediating effects of demand management flexibility on the relationship between physical distribution flexibility and relationship satisfaction .Employing moderated path analysis based on moderated regression analysis and condition -al nonlinear regression model , the paper takes an in-depth and comprehensive investigation on the moderating effects of environ -mental uncertainty on this mediation model .The results show that the direct effect of physical distribution flexibility on relation-ship satisfaction is stronger under an uncertain environment , while the direct effect of demand management flexibility on relation-ship satisfaction is stronger under a stable environment .In addition , the total effects of physical distribution flexibility on rela-tionship satisfaction cannot be influenced by external environment .Therefore, improving physical distribution flexibility and de-mand management flexibility together will increase relationship satisfaction , while the external environment should be considered first when each of the flexibilities is enhanced .
