【摘要】：我国已成为农产品进口大国,而所有农产品中都隐含有一定的耕地资源,论文基于农产品虚拟耕地资源的分析和评价,系统研究了我国大宗农产品贸易格局及对外依存度。论文所涉及的大宗农产品及其制品主要是土地资源密集型产品,包括粮食、油料、木薯、植物油、棉花、糖、饲料粕类等7大类,24个具体品种,以2000—2016年分国别的贸易数据为基础,从消费者的角度对大宗农产品虚拟耕地资源贸易量进行了分析和评价。研究结果显示,我国大宗农产品虚拟耕地资源净进口量由2000年的675×10~4 hm~2增加到2016年的5 928×10~4 hm~2,其中美国和巴西是中国农产品虚拟耕地进口量最大的国家,进口量分别由2000年的342×10~4 和146×10~4 hm~2,增加到2016年的2 101×10~4 和2 192×10~4 hm~2,占我国虚拟耕地进口总量比例超过70%;2016年农业耕地资源对外依存度达到30.5%,对巴西和美国的依存度分别为11.3%和10.8%。土地密集型农产品的大量进口,在一定程度上缓解了我国耕地资源紧张的压力,保证了粮食安全。
[Abstract]:China has become a big importing country of agricultural products, and all agricultural products have some cultivated land resources hidden in it. This paper is based on the analysis and evaluation of the virtual cultivated land resources of agricultural products. The trade pattern and external dependence of China's bulk agricultural products are systematically studied. The bulk agricultural products and their products are mainly land resource-intensive products, including grain, oil, cassava, vegetable oil, cotton, sugar, etc. Based on the trade data of different countries from 2000 to 2016, the trade volume of virtual cultivated land resources of bulk agricultural products was analyzed and evaluated from the point of view of consumers. The net import of virtual cultivated land resources of bulk agricultural products in China increased from 675 脳 10 ~ (4) hm~2 in 2000 to 5 928 脳 10 ~ (4) h / m ~ (2) in 2016. Among them, the United States and Brazil are the countries with the largest imports of agricultural virtual arable land in China. Imports increased from 342 脳 10 ~ 4 in 2000 and 146 脳 10 ~ (4) h ~ (-1) to 2 101 脳 10 ~ (4) and 2 192 脳 10 ~ (4) h ~ (-2) in 2016, accounting for more than 70% of the total import of virtual arable land in China. In 2016, the external dependence of agricultural cultivated land resources reached 30.5%, and the dependence on Brazil and the United States was 11.3%, respectively. And 10.8. massive imports of land-intensive agricultural products, To a certain extent, to ease the pressure on China's arable land resources, to ensure food security.
