我国锡资源国际供应链评价及对策研究
International Supply Chain of Tin Resources in China: Evaluation and Countermeasures
锡资源的稳定供应是保障我国信息化产业和新兴战略产业发展的重要基础,是实现制造强国和数字经济创新的重要战略支撑。当前我国锡资源需求量持续扩大,而国内已探明的锡资源难以满足消费需求,导致进口量持续攀升。因此,保障锡资源国际供应链安全愈加重要。本文从资源供给、贸易流通、循环利用三个维度剖析我国锡资源国际供应链的安全程度,为我国锡资源安全保障提供科学支撑。研究认为,我国锡资源供应链风险呈“V”形演变趋势,存在锡资源市场供给多元化不足,国内锡储量增长缓慢、选矿技术仍待提升,再生锡产量不足、循环利用率始终偏低等问题。研究建议,我国应提升国际供应链稳定程度和国内资源保障力度,加快外采多元化和拓宽海外资源布局,加大国内锡矿勘查力度和选矿技术的研发投入,优化锡资源战略储备布局,健全二次资源回收体系,综合提升锡资源的供应能力和安全保障程度。
The stable supply of tin resources is crucial for the development of China's information industry and strategic industries, serving as a key for strengthening the manufacturing sector and promoting digital economy innovation of the country. Currently, China's demand for tin resources continues to expand; however, domestic tin resources discovered through exploration are insufficient to satisfy the consumption demand, leading to a continuous increase in imports. Therefore, ensuring the security of the international supply chain of tin resources has become increasingly important. This study evaluates the security level of the international supply chain from three dimensions: resource supply, trade circulation, and recycling, providing scientific support for ensuring the security of tin resources in China. The findings indicate that China's tin supply chain displays a V-shaped risk profile; however, there are issues such as insufficient diversification in the supply of tin resources, slow growth in domestic tin reserves, subpar mineral processing technologies, inadequate recycled tin production, and persistently low recycling rates. This research suggests that China should enhance the stability of international supply chains, strengthen domestic resource security, and improve the system for the recovery of secondary resources. These measures are expected to accelerate diversification in external procurement, increase domestic investment in tin ore exploration and beneficiation development, and optimize the strategic reserve layout of tin resources, thereby comprehensively boosting the supply capacity and safety assurance of tin resources in China.
