以(火用)为自然资源的统一量化指标，编制了2000年中国经济资源核算。进入经济生产的主要资源有阳光、风电、潮汐能、波浪能、地热能、核电、生物质、秸秆、水电、煤炭、石油、天然气、木材、矿石、农水产品等。阐述了造纸、食品、钢铁、有色、化工等行业以及交通、家居、商业等行业的资源转换。还估计了包括照明、机械工作、空间加热、烹饪、水加热和过程加热在内的热转换程序的效率。中国经济的总(火用)投入为64.76EJ，为51.0GJ/帽，而总(火用)产出为12.8EJ或10.1GJ/帽，火用效率为20%。本研究阐明了提高不同转化部门(火用)效率的可能性，为政策制定者建立有效的经济生产监管机制提供了理论依据。(C)2006爱思唯尔B.V.保留所有权利。
The resource accounting of the Chinese economy in 2000 is presented based on exergy as a unified quantifier for natural resources. Major resources entering the economic production include sunlight, wind power, tidal power, wave power, geothermal power, nuclear power, biomass, straw, hydropower, coal, oil, natural gas, wood, ores, agricultural and aquatic products. The resource conversion embracing the paper, food, iron and steel, nonferrous metal, chemical and other industries as well as transportation, household and commerce sectors are illustrated. The efficiencies of the thermal conversion procedures including lighting, mechanical work, space heating, cooking, water heating and process heating are also estimated. The total exergy input of the Chinese economy was 64.76 EJ, which was 51.0 GJ/cap, whereas the total exergy output contained 12.8 EJ or 10.1 GJ/cap, indicating the exergy efficiency was 20%. The present study illustrates the possibilities of increasing exergy efficiencies of different conversion sectors and provides theoretical foundation for policymakers in establishing effective regulatory mechanism of economic production.
