    摘要:

    基于江苏省2012年投入产出表及水资源公报的统计数据,运用修正后的投入产出模型,定量计算江苏省贸易用水强度、虚拟水净输出量,并通过调整贸易结构,最大化实现节水效应。研究表明:2012年江苏省虚拟水贸易整体上呈现净流入,有利于节约省内水资源;从贸易额调整来看,在设定的5%、10%、15%3个调整幅度的基础上改变传统的贸易输出、输入结构,化学产品、煤炭采选产品部门出现大规模节水效应,随着调整幅度的增加,净输出量大的部门节水效应越来越大。江苏省虚拟水贸易是当前实现资源节约与经济发展的重要方式。

    Abstract:

    Based on the statistical data of input-output table and water resource bulletin of Jiangsu Province in 2012, the water trade intensity and the net outflow of virtual water are calculated by using the revised input-output model so as to realize the effects of saving water at the largest degree. The results show that there is a net virtual water inflow in Jiangsu Province in 2012 on the whole, and it is in favor of saving water. Under the given three specified trade input-output ranges of 5%, 10% and 15%, the industries of chemical products and coal mining products exhibit the large-scale water-saving effects. With the increase of the adjusted range of trade, the effects of saving water are larger and larger in the industries with large net outflow of virtual water. At present, the trade of virtual water is an important way of realizing resource saving and economic development, and it may provide basis and reference for the government to make decisions on structural adjustment of trade.
