摘　　要：为研究经济系统可持续发展进程中对自然物质的需求与消耗,综合运用物质流分析方法和结构分解分析方法,对中国经济系统1990～2002年间的自然物质投入进行分析计算.结果表明,1995～1999年间中国经济系统在保持自然物质消耗少量增加(以直接物质投入DMI为指标,年均增长约0.58%)的基础上实现了经济的较高速发展(以国内生产总值GDP为指标,年均增长约10%).为了实现经济发展的去物质化,必须在保持较低人口增长速率的同时大力提高技术水平,提高经济系统的资源生产效率.To study the requirement and consumption of natural materials in the process of sustainable development of economic system, the natural material input of China economic system during 1990 to 2002 was analyzed and calculated using complexly the techniques of material flow analysis (MFA) and structure decomposition analysis (SDA). China economic system during 1995 to 1999 realized higher rate development (using domestic producing total value GDP as index, annual average growth about 10%) based on the maintaining less increase of natural materials consumption (using direct material input (DMI) as index, annual average growth about 0.58%). In order to realize the dematerialization of economy development, while maintaining lower growth rate of population, the technological level must be enhanced vigorously to enhance the resource producing efficiency of economic system.
