中文摘要
农食价值链（AVCs）在主要处于农村的农民、渔民或牧民与日益城市化的消费者之间充当产品流动的中介。然而，历史上构建经济发展过程研究的理论模型假定排除了AVC功能，且AVC企业与工人必然被排除在生成农业与发展经济学文献中大部分实证发现的家庭数据之外。结果，本学科在某种程度上忽视了过去几十年来AVC的快速增长与结构变迁，这些变化使AVC成为主要的雇主与增加值来源，以及技术转移和外国投资的关键场所。本文提供了一个整合的、结构化的实证叙述，阐述AVC革命在发展中国家为何以及如何发生、这些变化的影响，以及这些结构变迁为经济学家提供的丰富经济研究机会。（JEL L14, L81, O13, O33, Q12, Q13, Q17）
Abstract
Agri-food value chains (AVCs) intermediate the flow of products between largely rural farmers, fisherfolk, or herders and increasingly urban consumers. The theoretical models that historically structured research on the economic development process assumed away AVC functions, however, and AVC firms and workers were necessarily omitted from the household data that generated most empirical findings in the agricultural and development economics literatures. As a result, the discipline has somewhat overlooked the rapid growth and structural change in AVCs over the past few decades that turned AVCs into major employers and sources of value addition, as well as key loci for technology transfer and foreign investment. This paper offers an integrated, structured, empirical narrative of how and why AVC revolutions occur in developing countries, the impacts of those changes, and the abundant economic research opportunities these structural changes afford economists.
