摘要
Copper metal is one important raw material of national economy, and its security is tightly linked with industrialization process. A comprehensive security evaluation index system, including three first class indicators, nine second class indicators and fourteen third class indicators, was constructed based on the pressure-state-response （PSR） model. And efficacy coeff^cient method was adopted in dimensionless treatment and entropy method was used to obtain the weight. Then, the data of China＇s copper from 1992 to 2011 were studied and collected. By processing these data, a comprehensive safety index of China＇s copper was got. The results showed that the comprehensive safety index of China＇s copper rose from its low point. The safety pressure state of China＇s copper was improved. The safety state of China＇s copper continued to be tight. The response state continued to rise. The overall situation of China＇s copper safety was improving, but still not optimistic.
铜在我国经济发展与国家资源安全方面扮演着重要角色。采用"压力状态反应"(PSR)模型,构建了一套包含3个一级指标、9个二级指标、14个三级指标的铜资源安全综合评价指标体系,并运用功效系数法进行数据无量纲化处理,熵值法进行赋权。然后,选取1992—2011年的数据,计算出中国铜的PSR安全综合指数。结果表明,中国铜资源安全综合指数在低位回升,安全压力在改善,安全状态仍持续紧张,安全响应水平在提升,但铜的总体安全态势仍不容乐观。
