中文摘要：

本文从供应商——制造商关系发展这一动态的角度探讨供应商专项投资与其感知合作风险之间的关系以及契约和关系规范的不同调节作用。通过对中国家电行业261对供应商与制造商的关系的问卷调查，采用因子分析和多元回归的方法对概念模型及假设进行验证。本文研究结果表明：（1）在不同的关系发展阶段供应商专项投资与其感知的合作风险有着显著的差异。（2）尽管契约和关系规范对供应商专项投资与其感知的合作风险间的正向关系有着负向调节作用，但在关系发展的不同阶段，这种调节作用也存在着显著的差异。本文对于认识和了解关系发展阶段中供应商专项投资带来的合作风险感知水平的变化以及两种不同控制机制调节作用的差异性具有重要的理论和现实意义。

英文摘要：

On a dynamic perspective, this paper examines the change of suppliers＇ perceived relational risks from the TSIs in the relationship with their manufacturers and investigates the moderating effects of contracts and relational norms on the perceived relational risks during the process of manufacturer- supplier relationship development. Through researching on the data from 261 supplier enterprises in Chinese household electrical appliances sector, the hypotheses are tested by using the factor analysis and multi- regression analysis. It argues that （1） Each relationship phase differently moderates the positive relationship between suppliers＇ TSIs and their perceived relational risks. （2） Although contracts and relational norms both have negative moderating effects on the positive relationship between suppliers＇ TSIs and their perceived relational risks, these moderating roles are different in various phases of a relationship. The research has drawn both the theoretical and managerial implications for understanding the changing of suppliers＇ perceived relational risks with TSIs involved in different rela- tionship phases and the differences of moderating effects of contracts and relational norms on the positive relationship between the suppliers＇ TSIs and their perceived relational risks.
