【摘要】：基于经济区域分析层次,运用多区域投入产出分析及有关差异分解方法,探寻生产视角下水足迹(生产水足迹)地区间差异及其成因,讨论有必要调整生产的地区及调整内容。研究结果显示:1中国生产水足迹总体空间差异主要源于经济区域间差异(贡献率69.46%);2中国西北、中部和东北区域生产水足迹高于其他经济区域;各经济区域生产水足迹均主要源于农林牧渔业;农林牧渔业生产水足迹经济区域间差异是中国生产水足迹经济区域间差异的最重要成因(贡献率59.19%),其关键因子为该部门最终需求量(贡献率74.57%);生产水足迹相关指标区域间比较中,京津区域水资源压力、西北区域生产水足迹强度、东北区域工业生产水足迹废弃率高于其他区域对应值;3各经济区域内省区间生产水足迹在总量、部门结构、差异成因上有异同,在生产水足迹相关指标上水平各异;4东北区域、上海等"很有必要"调整生产,而"有必要"调整的有京津区域、吉林等;具体调整应结合水足迹地区间差异及其成因分析结果进行。在生产视角下水足迹研究中引入经济区域分析层次、构建生产水足迹强度和工业生产水足迹废弃率指标,具有一定创新价值。
[Abstract]:Based on the level of regional economic analysis, using multi-region input-output analysis and related difference decomposition method, this paper probes into the regional differences of water footprint (production water footprint) from production perspective, and discusses the areas and contents of adjustment of production. The results show that the total spatial difference of water footprint in China is mainly due to the difference between economic regions (the contribution rate is 69.46%), and the water footprint of production in central and northeast China is higher than that in other economic regions. The water footprint of each economic region is mainly from agriculture, forestry, animal husbandry and fishery industry. The economic difference of water footprint of agriculture, forestry, animal husbandry and fishery industry is the most important cause of the economic difference of water footprint in China (the contribution rate is 59.19%, the key factor is the final demand of this sector (contribution rate is 74.57%); the correlation index of production water footprint is that of the final demand in this sector (contribution rate 74.57%). In the comparison between marked regions, The pressure of water resources in Beijing-Tianjin region, the intensity of production water footprint in northwest region, the waste rate of industrial production water footprint in northeast region are higher than the corresponding value in other regions. There are similarities and differences in the causes of the difference, in the production water footprint related indicators of different levels in the Northeast region, Shanghai and other "very necessary" to adjust production, and "necessary" adjustment of the Beijing-Tianjin region, Jilin and so on; The concrete adjustment should be carried out according to the difference of water footprint and its cause of formation. It is of certain innovation value to introduce the economic regional analysis level into the study of water footprint from the perspective of production, and to construct the index of production water footprint intensity and industrial water footprint abandonment rate.
