摘要
基于1994—2013年我国不同区域人均农产品虚拟水消费数据,运用σ收敛和β收敛分析了我国不同区域农产品虚拟水消费的敛散性。结果表明,西部地区的农产品虚拟水消费水平呈现出σ收敛,并且在农产品虚拟水消费上呈现显著的β收敛;而东部地区和中部地区的农产品虚拟水消费的收敛性检验均没有通过,呈现出发散的趋势,说明我国东部地区和中部地区与西部地区农产品虚拟水消费逐渐拉开距离,单位面积粮食产量会促进不同区域农产品虚拟水消费差异的缩小,但是由于不同区域的居民人均可支配收入存在较大的差异,会不利于各区域甚至全国的农产品虚拟水消费收敛。
This paper adopts per capita agricultural product virtual water consumption data based on 1994-2013 years in different regions of China to do σ convergence test and β convergence test in different regions of China agricultural product virtual water consumption of the convergence and divergence. The result shows that agricultural product virtual water consumption level shows sigma convergence in the western region and growth rate shows significant β convergence in agricultural product virtual water consumption.And the convergence of the agricultural products virtual water consumption doesn＇t pass in the eastern and central regions, showing a trend of divergence, which shows that the virtual water consumption of agricultural products in the eastern and central regions of our country is gradually pulled apart; the grain yield per unit area will promote the reduction of the virtual water consumption of agricultural products in different regions, but it is not conducive to the regional and even the country＇s agricultural product virtual water consumption because of the large differences of residents income in different regions.
