摘要
对一般的物质投入产出表进行了改进,主要依据可操作性原则调整了部门分类和基本假定,通过设置资源恢复部门,着力反映经济系统的物质循环利用情况。之后,利用中国现有的数据基础,对2004—2015年中国经济系统的物质存量进行估算,并展开了经济系统内部部门间的物质流动测算,在此基础上对物质投入产出表的物质消耗系数、物质循环效率进行了系统分析。结果显示:随着时间的推进,部门层面的物质消耗系数的变化并不明显,但总体上初始物质投入的物质使用效果呈现向好的态势,经济系统的物质循环利用效率有所提高;目前中国的环境压力还没有明显缓解的趋势,需要进一步在宏观层面上加强对物质流动总量和物质循环结构的调控,提高物质利用效率,推动废弃物质的资源化和提升再利用程度。
The general physical input-output table has been revised in this paper. The revision included adjusting the sector classification and basic assumptions based on the principle of operability and setting up the resource recovery sector to reflect material recycling.According to the existing database of China,the material stock of the economic system of China from 2004 to 2015 is estimated. Then the material consumption coefficient and the material cycling efficiency are systematically analyzed following a measurement of the material flow among internal sectors of the economic system. The results show that the change of material consumption coefficient at sector level is not obvious,but the utility effect of initial material input shows a good trend overall and the efficiency of material recycling increases. The current environmental pressure in China does not ease the trend. It is necessary to further strengthen the regulation of the total material flow and the material circulation structure at the macro level. The efficiency of material utilization should be increased and the recycling and reuse of waste materials should be promoted.
