Advantage Value of Regional Virtual Water Strategy(AVRVWS) is defined to estimate the feasibility of implementing virtual water strategy and the regional economic, social and ecological effects to different regions under virtual water strategy background all over the world.The connotation and impact factors of AVRVWS are analyzed afterwards, then an assessment index system including 12 indices is established, which consists of four aspects: supply of water resources, demand of non-agricultural water resources, water resources management and development of agriculture.And the grades of AVRVWS of 31 provinces in China are calculated.The assessment results demonstrate that the grades of AVRVWS in China have notable regional discrepancy.Most of the provinces have the medium grades of AVRVWS, the grades in east China are higher than those the west region, and the grades in the south and north are higher than those of the central region.The grades of AVRVWS in Inner Mongolia, Shanxi, Beijing, Tianjin in North China and Hainan, Guangdong, Guangxi, Zhejiang, Fujian, Hunan, Jiangxi, Shanghai in the south eastern China is the highest in China, so they are the key regions of the virtual strategy research and practice in China.
