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。
Copper plays an important role in China’s economic development and national resource security. A comprehensive evaluation index system of copper resources security, including three first-level indicators, nine second-level indicators and fourteen third-level indicators, was built using the PSR model and the efficiency coefficient method Dimensionless data processing, entropy method for empowerment. Then, we select the data of 1992-2011 to calculate the China PSR safety composite index. The results show that China’s copper resources safety index rebounded in the low, safety pressures are improving, the security situation continues to be tight, the security response is improving, but the overall security situation of copper is still not optimistic.
