黄河流域虚拟水贸易核算及影响因素研究
Study on Virtual Water Trade Accounting and Its Influencing Factors in the Yellow River Basin
摘要
Abstract
In order to quantify trade-associated virtual water flows and evaluate their impact on regional water systems,this paper used the multi-region input-output model to reveal the pattern and structure of the virtual water trade inside and outsided of the Yellow River Basin in 2012,2015 and 2017 and used LMDI method to analyze the impact of the virtual water net output of the watershed relative to others,and used the QAP model to analyze the impact factors of the virtual water trade among provinces within the watershed.The results show that a)the Yellow River Basin as a whole presents a virtual water net input state,but the Yellow River Basin net exports virtual water to Beijing,Tianjin,Hebei and other 12 regions.b)The virtual water trade export industry is mainly the production and supply of agriculture,electricity,gas and water.c)Structure effect and in-tensity effect are important driving factors of virtual water net output in the watershed.d)QAP regression outcomes prove that economic development level,geographic distance and water use intensity differences are the main factors affecting the virtual water trade.关键词
