中文摘要：

在现有的质量规制政策下，食品质量安全事故频繁发生的原因是强制性公共规制难以有效地介入食品供应链的质量生产过程。对供应链生产过程的公共规制失灵，为被规制者以质量手段谋求利益最大化留下了充分的对策性空间。由供应链核心厂商实施的私人质量规制，以其信息成本优势、对策性行为少和规制的可持续性，能够有效地弥补公共规制对供应链的质量规制空白。

英文摘要：

Under the current quality regulation policies, the causes of many food safety incidents are that it is difficult for mandatory public regulation to intervene in the production process of food supply chain. The quality regulation failure of food production process leaves enough space for the regulated firms to make a profit by means of quality degradation. The private quality regulation conducted by core firm in food supply chain can fill the gap that pubilc regulation cannot intevene in the production process with the advantages of information cost, few games behavior and regulation sustainability.
