摘 要：
全球经济危机引发了各国对于贸易限制措施的迫切需求,贸易限制会导致农产品种类的减少,而农产品种类的减少又会引发农产品进口国福利的相关变化。本文在WTO框架下思考贸易限制措施,从福利测算的新视角——产品种类出发,分析贸易限制与商品种类的关系,并对金砖国家的农产品进口的集约进口边际、广义进口边际以及进口福利进行测算分析。研究发现,金砖国家农产品广义进口边际值总体上远高于集约进口边际值,这意味着金砖国家农产品贸易的增长主要源于新产品种类的逐渐丰富,而不是单纯依赖原有农产品量的扩张;从产品种类和福利变化上看,金砖国家的农产品进口关税与其福利基本呈现逆向关联。

摘 要：
Present global economics crisis triggers the compelling demand of trade control measures,trade limit will lead to the reduction of agricultural variety,which will result with corresponding variety gains change of agricultural importing countries. This paper thinks over trade control measures under the framework of WTO,selects a new method to estimate countries' welfare from the variety change and analyses the relation between trade limit and product variety. Making use of the Brics' agriculture importing data of CEP Ⅱ- BACI database,and of relevant research methods of dual margin and newnew trade theory,this paper figures out the IM,EM and variety gains of the Brics' agriculture. The empirical results show that the Brics' agriculture EM is much higher than IM,signifying the growth of the Brics agricultural products trade mainly from gradually rich product category,rather than the volume expansion of original agricultural products. Judging from the variety gains,the Brics' agricultural products import duties have a reverse relationship with their welfare. Based on these results,this paper puts forward the policy suggestions from four aspects to promote the Brics' multilateral cooperation.
