摘要： 将金属物质流分析与金属产品生命周期链群结合起来,构建了金属物质社会蓄积量理论分析模型.由该模型分析得出,金属物质社会蓄积量及其净增量与金属制品消费量、消费量的年变化率和金属制品使用寿命密切相关.初始年的金属制品消费量愈大、消费量的年变化率愈快、金属制品使用寿命愈长,金属物质的社会蓄积量及其净增量就愈多.金属制品使用寿命超过平均使用寿命而延长时,金属物质社会蓄积量的回收率将降低.分析结果对于金属工业产业政策的制定有一定的参考价值.

Abstract: Combining substance flow analysis and groups of products life cycle chains, a theoretical analysis model for social stocks of metallic substance was developed. It is concluded from the model that the social stocks of metallic substance and their net increments are closely related to the factors such as metal product consumption, annual variation rate of metal product consumption and service lives of metal products, i.e., they will increase with the increase of the three factors. If the service lives of metal products are prolonged beyond average service lives, recycling rate of the social stocks will decrease. Analysis results can provide some reference for the decision making on industrial policies of metal industry.
