转基因食品标签管制方式的经济学分析

An Economics Analysis on Labeling Administration for Transgenosis Foods

目前各国对转基因食品采取了"不加贴标签"、"自愿加贴标签"以及"强制性加贴柝签"等三种标签管制方式。本文应用消费者拟线性效用函数模型,对强制性加贴标签管制方式对消费者福利的影响进行了深入探讨。在此基础上通过对现有三种标签管制方式的比较分析,确定了各种标签管制方式实施的条件与影响,并认为在我国现有条件下,只要检测成本不高到难以承受的地步,对转基因食品应采取强制加贴标签管制方式。

Three labeling administration as 'no labeling', 'voluntary labeling' and 'compulsory labeling ' are applied in different countries. The paper develops a model of quasi-linear consumer utility function to make analysis on welfare of consumers under administration of compulsory labeling, and draws up the possibility of such measure as long as the testing cost for transgenosis foods is affordable.
