摘要: 虚拟资源对于揭示农产品贸易隐含的资源流动及效应具有重要意义。随着我国农产品贸易量和贸易格局的变化,定量核算我国农产品贸易隐含的土地资源量变化,可以从资源利用的角度评价我国农产品贸易的合理性,为相关贸易政策的制定提供理论依据。研究重点探讨了农产品及加工制品的虚拟土地资源量的核算方法,分别从生产者角度和消费者角度对1986—2009年我国农作物产品及其加工制品贸易的虚拟土地资源量进行了核算。计算结果表明,我国农作物产品隐含的虚拟土地资源量由1986年的净出口442.6×104 hm2,转变为2009年的净进口2 889.0×104 hm2,假设进口农产品在本国生产的情况下,2009年我国所需的虚拟土地资源量为3 817.5×104 hm2。从虚拟土地资源进口结构和空间分布来看,我国虚拟土地资源净进口主要作物类别由谷物转变为油料作物,主要进口来源国由美国、加拿大、澳大利亚转变为美国、巴西、阿根廷。

Abstract: The liberalization has greatly accelerated the volume of international trade of agricultural products in past decades. International trade has become increasingly important in connecting areas with resource surplus and deficit. Trade in agricultural commodities is ultimately an exchange of services and resources incorporated into the traded goods. Resources flow and the associated ecological impacts have been a hotspot in agricultural trade and environment study. This paper attempts to contribute to both the calculation method of the virtual land use and China’s virtual land quantification of crop trade. It aims to: 1) explore the method to quantify the virtual land hidden in agricultural trade flows. The conversion factors have been used to calculate the processed products based on the caloric equivalent method and the product tree method. 2) The virtual land use hidden in the imports and exports of China’s crop trade was measured, considering both primary products and their processed products trade with other countries in 1986-2009, from both the producer and consumer’s perspective to illustrate the results more clearly. The results show that China’s crop products import has increased greatly during 1986-2009, the virtual land use hidden in international trade has increased from -442.6×104 hm2 in 1986 to 2 889.0×104 hm2 in 2009, the changing trend and the quantity varied between different categories, the main category of the virtual land use has changed from cereal crops to the oil crops, which take 88.0% of the whole virtual land use in 2009, soybean takes the major weight of the oil crops import; the geographic location of the virtual land use has changed from the North America to the South America, the North America and the Southeast Asia; the crop trade between China and other countries releases China’s land use pressure, but the socio-economic and environmental impact of the virtual land also need to be assessed in order to make the virtual land use sustainable.
