【摘要】 锡作为我国重要的战略资源,对我国经济发展有重要影响。近年来,随着我国经济的快速发展,锡资源供不应求的问题逐渐凸显,开展锡资源供应安全评价对提高资源保障具有重要意义。本文采用2000～2017年数据从资源因素、供需因素、风险因素和可持续因素四个维度出发构建了包含十六个指标在内的中国锡资源安全评价指标体系,并采用改进的熵权层次分析法对中国锡资源供应安全进行评价。结果表明:锡资源供应安全状况在资源因素、供需因素、风险因素和可持续因素的相互作用下整体呈恶化趋势,安全等级由安全到危险。尽管可持续因素对锡资源的供应安全起积极作用,但无法弥补资源因素、供需因素、风险因素对锡资源供应安全产生的负面影响。更多还原

【Abstract】 As an important strategic resource in China,tin plays an important role in China’s economic development.In recent years,with the rapid development of China’s economy,the shortage of tin resources has become increasingly prominent.It is of great significance to carry out supply safety evaluation of tin resources to improve resource security.Based on the data from 2000 to 2017,this paper establishes a Chinese tin resource safety evaluation index system including sixteen indicators from the four dimensions of resource factors,supply and demand factors,risk factors and sustainability factors,and evaluates the security of tin resources supply in China by using improved entropy weight analytic hierarchy process.The results show that the security status of tin resources supply is deteriorating in the interaction of resource factors,supply and demand factors,risk factors and sustainable factors,and the security level is from safety to danger.Although sustainable factors play apositive role in the supply security of tin resources,it cannot compensate for the negative impact of resource factors,supply and demand factors and risk factors on the supply security of tin resources.更多还原
