运用委托代理理论在双边道德风险条件下从供应链管理的视角分别构建了基于内部质量检测的担保契约和基于外部故障检测的担保契约,并对两种质量担保契约对Saa S供应链的协调效果进行验证及对比分析。研究结果表明,基于外部故障检测的担保契约只有在故障检测不会错误地判定软件开发商所承担的质量担保责任时才能实现供应链的协调,而基于内部质量检测的担保契约无需约束条件便可实现供应链协调;以Saa S提供商期望收益最大化作为决策标准,基于内部质量检测的担保契约优于基于外部故障检测的担保契约。
Using the principal-agent theory, we construct a guarantee contract based on internal quality inspection and a guarantee contract based on external fault detection from the perspective of supply chain management under the condition of bilateral moral hazard and the coordination effect of the two kinds of quality guarantee contracts on Saa S supply chain For verification and comparative analysis. The results show that the guarantee contract based on external fault detection can only supply chain coordination when the fault detection will not wrongly determine the responsibility of quality guarantee borne by software developers, and the guarantee contract based on internal quality inspection can be without constraint In order to maximize the expected profit of SaaS providers as a decision criterion, the guarantee contract based on internal quality inspection is superior to the guarantee contract based on external fault detection.
