摘　　要：将人类社会经济系统看成自然生态系统中的一个子系统,研究该系统物质代谢的数量和质量,是目前产业生态学前沿研究的重点。本研究对辽宁省自1990年至2003年间的物质代谢情况进行了核算和分析研究,从区域物质流情景的角度入手,推进了中国经济系统的物质代谢及产业生态学的研究,并与国内国际相关研究成果进行了对比。结果表明自1990年以来,辽宁省社会经济系统物质代谢的变化过程与全国过程有一定的类似,其所消耗的自然资源绝对数量较大,相对数量也高于全国平均水平。然而数量上的优势并没有能够高效率的转化为经济上的贡献,其自然物质生产效率不仅低于全国平均水平,而且也远远低于国际先进水平,以2003年单位自然物质投入所产生的GDP为例,该值仅相当于2000年欧盟15国平均水平的30%,1996年日本平均水平的10%。辽宁省高数量的自然资源消耗并没有换来高质量的回报。最后对物质流核算与分析方法的发展进行了一定的探讨。Studying the quantity and quality of material metabolism in the socio-economic system, which is regarded as a sub-system of natural ecology system, is now the outstanding emphasis of Industrial Ecology research. Such research done in China mainly concentrated on national economic system. More detailed analysis on its sub-area, such as a province, is a useful way to expand the research works of material metabolism and Industrial Ecology, and is also helpful to the sub-area＇s sustainable development. Based on the Accounting and Analysis （MFA） method of Material Flow applied in western countries, the Liaoning Province in China was chosen as study area. The research can be regarded as the first attempt for studying the material metabolism at province level in China, and it also promotes the research works of material metabolism and Industrial Ecology in China. Considering the limitation of data of material import and export, a set of new indicators is developed to illustrate the natural resources consumption in Liaoning Province. The study calculates the material indicators of Liaoning from 1990 to 2003, from the input and output perspectives. These indicators are then connected with economic and demographic indicators to create new indicators, which scale the material intensity and efficiency of Liaoning＇ s economy. The results showed that the changing process of material metabolism in Liaoning is similar with that of China in the same period. The changing process can be divided into three phases, which are highly consistent with the Eighth, Ninth, and Tenth Five-Year Plans implemented by Chinese government. It can also be seen as the obvious evidence that material metabolism of an economics system is greatly influenced by the macro-policy. The absolute amount of material metabolism in Liaoning is high, and the relative number is also higher than the average level of the whole China. However, the quantitative advantage of material metabolism did not lead to high economic return. Liaoning＇ s physical produc
