食品伙伴网讯 据sciencedirec数据库消息，近日《食品政策》（Food Policy）杂志刊登了一项有关苹果和梨等水果农残限量法规对国际贸易影响的文章。
本论文中，作者研究了农药最大残留限量（MRLs）法规对苹果、梨和相关加工产品的国际贸易影响，目的是了解法规的相似性和差异性对贸易的影响。本次研究显示，各国的法规差异会阻碍国际贸易的进行。
部分原文报道如下：
In this paper we study the impact of the regulations on Maximum Residue Levels （MRLs） of pesticides on the trade of apples and pears and related processed products with the aim of understanding how their similarity （or dissimilarity） affect trade. Most studies investigate the impact of sanitary regulations introducing directly in the analysis the MRL put in force in the importing country.
They introduce in the analysis the level of the regulation in the importing country without taking into account the rule in force in the exporting country. Rather than focusing on a particular pesticide we take into account the entire list of substances set out by the various regulations. We then build a similarity index and introduce it into a gravity equation to assess the impact of the differences in MRL of pesticides on trade. Results suggest that the differences between regulations matter and may, in some case, hinder trade.
