1987～2005年水的生产和供应部门对国民经济影响分析

Impact on national economy of water production and supply sectors during 1987～2005

针对水的生产和供应部门近年来的快速发展,应用1987～2005年5张32部门可比价投入产出表分析了水的生产和供应业影响力系数变化的趋势及原因,并且重点分析了农业、水的生产和供应业、电力热力生产业等部门对水的生产和供应部门的完全消耗系数的变化,发现水的生产和供应部门对国民经济的影响正逐步增大,供用水正向合理化发展。

With regard to the rapid development of water production and supply sectors in recent years,the changing trends and causes of influence coefficient of water production and supply sectors were analyzed based on 5 input-output tables of 32 sectors during 1987～2005.The impact of agriculture,water production and supply,thermal and electrical power production industry on the total consumption coefficient of water production and supply sectors was highlighted.It is found that the impact of water production and supply sectors on the national economy gradually increases,and water supply and consumption are being rationally developed.
