中文摘要：

人的因素是影响过程质量成效的重要因素。由于质量的事后验证性和过程的不易监控，企业所有者和生产性员工之间存在关于过程的信息不对称，导致生产性员工往往注重量，有选择性地忽视质。基于信息不对称理论，构建企业所有者和生产性员工之间质量“委托一代理”模型，从经济学视角讨论如何激励生产性员工增加质量投入，提高过程质量成效，对如何在实践中推广模型的应用给出若干建议。

英文摘要：

Workers are key factors that affect product quality in process. Because of the asymmetric information between enterprise owners and their workers, with post-verification feature of quality and not-easy- to-monitor process details, workers tend to focus on quantity and selectively ignore quality. Based on the asymmetric information theory, a principal-agent model of product quality in process between enterprise owners and their workers is established and discussed from the perspective of economics and the effective ways to motivate workers in quality improvement, and finally several suggestions are given on how to promote the model＇s using in practice.
