摘　　要：为了从经济学角度,量化分析水资源对成都市经济发展的约束效应以及国民经济各部门的用水特性,借用"木桶"原理,运用经济学发展理论和投入产出技术,对成都市水资源的"矮板效应"、"高板效应"和"疏板效应"进行分类计算分析。结果表明:目前水资源还不是约束成都市经济发展的"瓶颈"资源,但在时间和空间上,其约束程度表现出一定的差异性;农业、餐饮业等部门浪费水资源较严重,用水量与城市化水平还未呈现合理的倒"U"形关系;水资源在各部门间配置还欠合理,在建筑业、文化娱乐和房地产业等配置较多,而对交通运输、工业和金融业等配置较少。Based on the Wooden Barrel Principle,the highest board′s effect,the lowest board′s effect and the sparse board′s effect on the water resources in Chengdu City are analyzed respectively with development economics theory and input-output technology.The result shows that,the water resources is not the bottleneck that restricts the economic development in Chengdu,however,to some extent,the constraint intensity of water resources is distributed unevenly both in time and space.The problem of water resources wasting is serious in agriculture and catering industry,and the relationship curve of water utilization and urbanization is not an invert-U type.Therefore,the water resources are not reasonably allocated in different sectors.Excessive water is allocated to the industries of construction,cultural entertainment and real estate,while less water to the transportation,industry and finance.
