摘要：以角色外利他行为和渠道行为治理的相关研究作为理论基础，讨论经销商角色外利他行为对渠道关系中合作效率和合作公平的影响，并检验合同治理和关系治理的调节作用。从经销商的角度收集到有效问卷343份，使用多元层次回归分析的方法进行假设检验。本文的实证结果表明：第一，经销商角色外利他行为能够促进其同供应商之间的合作效率和合作公平；第二，与关系治理相比，合同治理会强化经销商角色外利他行为对合作效率的影响；第三，与合同治理相比，关系治理会强化经销商角色外利他行为对合作公平的影响。最后，文章从理论贡献、管理启示和研究不足及未来研究方向等方面对本文的研究结果进行了讨论。

Abstract: Based on related researches such as extra-role altruistic behavior and channel behavior governance theory, this paper studies the influence of dealers' extra-role altruistic behavior on the efficiency and fairness of channel governance, and examines the moderating role of contract governance and relationship governance. Taking the cooperative relationship between suppliers and distributors as the research situation, 343 valid data were collected from the perspective of distributors, and statistical methods were applied to analyze the data and test the hypothesis. The research results show that: firstly, dealers' extra-role altruistic behavior can promote the cooperation efficiency and cooperation fairness between them and suppliers. Secondly, compared with relationship governance, contract governance will strengthen the dealers' extra-role altruistic behavior on cooperation efficiency. Thirdly, compared with contract governance, relationship governance will strengthen the impact of dealers' extra-role altruism on cooperation fairness. Finally, the research results are discussed in terms of theoretical contributions, implications for practical applications, research deficiencies, and future research directions.
