中国农产品国际贸易中虚拟土含量测算及其结构调整分析——基于粮食安全视角

选取谷物类、油料油脂类、糖料类、主要畜产品和棉花、蔬菜等农产品作为研究对象,运用热量当量法、产品树法以及料肉比法,进口从消费者角度,出口从生产者角度,对各类农产品在1995—2019年的进出口量进行虚拟土资源含量测算并观察净进口结构的动态调整特点。结果表明,我国农产品虚拟土进口总量呈明显的增长趋势,且不同类型农产品对节约国内土地资源的贡献度不同,在考察期内,贡献度的大小出现了明显的结构调整。最后,就合理配置国内土地资源以及高效利用国际土地资源以规避新的粮食安全问题提出相应建议。

Calculation of Virtual Soil Content and Analysis of Structural Adjustment in International Trade of Chinese Agricultural Products:From the Perspective of Food Security

Cereals,oils and fats,sugars,main livestock products,cotton and vegetables were selected as the research objects.The calorie equivalent method,product tree method and feed-to-meat ratio method were used,and import from the perspective of consumer while export from perspective of Producer,the virtual soil resource content of 1995-2019 import and export volume of various agricultural products was measured and the dynamic adjustment characteristics of the net imports structure were observed.The results show that:the total volume of virtual soil imports of agricultural products in China shows a clear growth trend,and the contribution of different types of agricultural products to the conservation of domestic land resources has undergone structural adjustment.Finally,it puts forward corresponding suggestions on how to rationally allocate domestic land resources and efficiently use international land resources to avoid new food security issues.
