山东省水资源价格波动效应的投入产出分析

针对水资源价格波动引起的国民经济各部门价格连锁反应问题,利用2012年山东省42部门以及139部门国民经济投入产出表,对水资源生产各部门的用水量进行分配,调整了投入产出,得到平衡的15部门价值型水资源投入产出表;应用投入产出价格波动模型分别计算50%、75%、100%3种水价上调方案对其他14部门以及对农业、工业、商业、公共服务四大产业价格的影响程度。研究结果表明,受影响最大的是公共服务部门,其次是农业、工业、商业,总体来说,水价提高对各类产品价格的影响程度均较低。

Input-output analysis of price fluctuation effect of water resources in Shandong Province

With regard to the chain reaction of various sectors of the national economy induced by the price fluctuation of water resources, the water amounts of various sectors for water resources are allocated and the input-output is adjusted, and the input-output table of equilibrium 15 sectors with value-type water resources is obtained by use of the input-output table of the national economy of 42 sectors in Shandong Province and national 139 sectors in China. The input-output price model is employed to calculate the influence degrees of three price adjustment schemes of 50%, 75% and 100% on agriculture, industry, commerce and public service and other 14 sectors. The result shows that the public service sector is the most greatly affected, followed by the sectors of agriculture, industry and commerce. The promotion of water price has low influences on the prices of various kinds of products.
