- Abstract
Virtual water trade provides a new way to solve the problem of uneven distribution of water resources in regional entities. An evaluation index system with 13 indexes of three levels was established to identify the influence factors in virtual water flow. A consistency test was completed, and the weight value of each index was calculated by using the analytic hierarchy process. Results show that the most important factor that affects the degree of virtual water flow is the water footprint per capita, with a weight of 0.27. The sum of weights of per-capita water footprint, per-capita water resources, dependency index, food security index, food self-sufficiency, and water-resource pressure index is up to 0.79, which indicates that the six influence factors determine the virtual water flow. The conclusions provide references in formulating measures to alleviate water resource shortages.
