摘　　要：为了分析中国的物质资源利用情况在国际上所处的位置,利用物质流分析方法,选取中国国内资源开采量(DEU)和相应的资源生产率(RP)为指标,研究了16个不同经济发展水平国家的资源利用情况,归纳出5种不同的资源利用特征,并将DEU与经济发展、资源生产率与能源消耗强度进行关联分析。分析结果显示:中国的DEU总量大,基于DEU的资源利用效率较低(2007年RP为0.26 USD/kg),资源的利用与经济发展和能源消耗紧密相关。结合国际上其他国家的发展经验,提出调整产业结构、转移资源压力、建立循环经济评价指标与核算制度等政策建议。Material flow analysis was used to locate China＇s natural resource utilization level in the world.Two indicators,domestic extraction used（DEU） and resource productivity（RP）,were employed to study resource utilization status in 16 countries at different economic development levels,from which 5 characteristics of resource utilization were identified.This paper then analyzed the relationship between DEU and economic development and the relationship between RP and energy intensity.The results indicate that China holds a large amount of DEU and a relatively low resource productivity（0.26USD/kg in 2007）.The use of resource is closely related to economic development and energy consumption.Based on the analysis in combination with other countries＇ experience,this study presents policy recommendations including adjusting industrial structures,transferring resource pressure and establishing indicator accounting systems to measure the development level of circular economy.
