Through case study solution evaluation of input output tables of 30 provinces in China in 2012, case study solution traits of virtual water trade during this region are expected through the use of a multi nearby input output MRIO model. The effects show that: 1 case study solution YRB had a net inflow of . With case study answer drawing close need of neighborhood environmental protection and sustainable economic development, case study answer idea of virtual water is regularly occurring to solve case study solution challenge of neighborhood water shortage. In this paper, nine provinces, namely Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan, and Shandong in case study solution Yellow River Basin YRB, are taken as case study answer research gadgets. Through case study answer analysis of input output tables of 30 provinces in China in 2012, case study solution features of digital water trade during this region are predicted through the use of a multi local input output MRIO model. The results show that: 1 case study solution YRB had a net inflow of .
