贸易自由化和区域经济一体化不仅会通过比较优势整合市场、提升效率,还会带来农产品贸易中虚拟资源的流动。以中国—巴基斯坦大米贸易为研究对象,使用两国大米贸易数据,首先检验中巴粮食市场整合程度,其次分析中巴大米贸易带来的虚拟水和虚拟土地的流动。结果表明:(1)中巴之间大米市场已经高度整合,且价格存在长期均衡,但巴基斯坦大米价格比中国波动大,其对中国大米的价格弹性为1.097;\"一带一路\"倡议带来了巴方大米价格7.8%的下降,增加了穷人的福利。(2)贸易带来了虚拟水土资源的流动。中国累计从巴基斯坦净进口大米354万t,相当于净进口国内52万hm^(2)、巴基斯坦96.4万hm^(2)耕地,以及国内34....

Trade liberalization and regional economic integration will not only lead to market integration and efficiency improvement through comparative advantages, but also produce transaction of "virtual resources", such as "virtual water" and "virtual land".

Secondly, we calculate the net flow of virtual water and virtual land resources accompanied by the rice trade, and analyze changes in resource efficiency. The results...
