摘要: 长江经济带的水生态环境问题受到越来越多人的关注,灰水足迹作为反映水污染强度的指标受到广泛的认可。为推动长江经济带实现高质量发展,对长江经济带的灰水足迹进行测算显得十分必要。文章基于2002年、2007年和2012年长江经济带各省份的投入产出表,编制了长江经济带的灰水足迹投入产出表,并建立只考虑进口的行业灰水足迹模型,测算得到长江经济带各行业的灰水排放系数和灰水足迹。结果表明:1)2002—2012年长江经济带16个行业的直接、间接和完全灰水排放系数均呈现下降趋势;2)2002—2012年长江经济带16个行业中有12个行业的完全灰水足迹下降,4个行业的完全灰水足迹上升;3)2002—2012年4个完全灰水足迹上升的行业分别为食品制造及烟草加工业、木材加工及家具制造业、石化工业和建筑业,导致这4个行业完全灰水足迹上升的主要原因在于其行业规模的扩大,其中,建筑业规模扩大的环节在直接方面,其余3个行业规模扩大的环节在间接方面。

Abstract: Water eco-environmental problems in Yangtze River economic zone attract more and more public attention. Gray water footprint as a marker to pollution degree is largely accepted. Estimation of industrial gray water footprints in Yangtze River economic zone is key to reach a quality economic development. This paper uses provincial input-output tables in Yangtze River economic zone in 2002, 2007 and 2012 to compile gray water footprint input-output table of Yangtze River economic zone, and estimates their gray water emission coefficients and footprints on imported industries. During 2002 to 2012, their direct, indirect and complete gray water emission coefficients in 16 industries are declining, and 12 are falling in complete gray water footprint while four rising which include food & tobacco industry, wood and furniture manufacturing, petrochemical industry and construction because of their expanding sizes, directly in construction and indirectly in the other 3 industries.

Key words: input-output table, Yangtze River economic zone, gray water emission coefficient, industrial gray water footprint
