本文运用投入产出模型测算了2005年和2010年中国工业出口贸易的灰色水排放强度与灰色虚拟水流量,并利用LMDI因素分解方法分析了工业出口的规模变化、灰色水排放强度与贸易结构变化对中国工业出口贸易中灰色虚拟水流量的影响。研究表明:中国工业出口贸易的灰色水排放强度降低与结构优化有效遏制了出口规模扩大所带来的灰色虚拟水排放量的增长,实现了工业出口贸易中灰色虚拟水流量的负增长。此外,本文还根据研究结论对其政策含义进行了探讨。
This paper uses input-output model to calculate gray water discharge and gray water discharge of China’s industrial exports in 2005 and 2010, and analyzes the scale change of industrial exports, the intensity of gray water discharge and trade structure changes by using LMDI factorization method Impact on Gray Virtual Water Flow in China’s Industrial Export Trade. The research shows that the decrease of gray water discharge intensity and structural optimization in China’s industrial export trade can effectively curb the growth of gray virtual water discharge caused by the expansion of export volume and achieve the negative growth of gray virtual water flow in industrial export trade. In addition, this article also discusses its policy implications based on the conclusions of the study.
