This article analyzes how value chains play a role in the political economy of agricultural and food policy by (1) discussing historical insights; (2) reviewing an emerging literature on political economy of trade policy and value chains and drawing implications for agricultural and food policy; (3) discussing market power issues with increasing concentration in agri-food value chains and its implications for government regulations; and (4) presenting a political economy case study of recent regulations that have explicitly targeted value chain structures in the agri-food sector: the EU regulations on “unfair trading practices (UTPs)”. The case study is of wider relevance since it addresses a key concern in global value chains.

从不公平的价格到不公平的贸易行为：政治经济、价值链和 21 世纪的农业食品政策

本文通过以下方式分析价值链如何在农业和食品政策的政治经济中发挥作用：（1）讨论历史见解；(2) 审查关于贸易政策和价值链的政治经济学的新兴文献，并对农业和食品政策产生影响；(3) 讨论随着农业食品价值链日益集中的市场支配力问题及其对政府监管的影响；(4) 对近期明确针对农业食品部门价值链结构的法规进行政治经济学案例研究：欧盟关于“不公平贸易做法 (UTP) ”的法规。该案例研究具有更广泛的相关性，因为它解决了全球价值链中的一个关键问题。
