中文摘要：

探讨供应商感知的承诺不对称性影响供应商信任的边界条件，用多元层次回归分析方法检验了两个假设。结果显示：①供应商感知的承诺不对称性对企业间信任确有显著影响；②在供应商认为自己的承诺水平高于分销商的承诺水平时，分销商的交易专有资产投入会强化供应商感知的承诺不对称性对信任的负向影响，而在供应商认为自己的承诺水平低于分销商的承诺水平时，分销商的交易专有资产投入会强化供应商感知的承诺不对称性对信任的正向影响。最后讨论了研究结论在企业渠道管理中的应用。

英文摘要：

The boundary conditions of the impact of suppliers＇ perceived asymmetry of commitment on interfirm trust was investigated, and two hypotheses by using hierarchy regression analysis were verified. The results show that： firstly, the suppliers＇ perceived asymmetry of commitment has significant influence on interfirm trust; secondly,when suppliers＇ commitment is higher than the distributors＇ commitment, distributors＇ transaction specific asset investments strengthen the negative influence of perceived asymmetry of commitment on interfirm trust; When suppliers＇ commitment is lower than the distributors＇ commitment, distributors＇ transaction specific asset investments enhance the positive relationship between perceived asymmetry of commitment and interfirm trust. The applications of the findings in marketing channel management was discussed in the last part.
