碳酸锂供需矛盾日益突出,科学预测未来中国碳酸锂需求量,对碳酸锂生产、进出口计划以及国家能源政策的制定具有重要意义。结合基于灰色关联分析和ARIMA-GM-BP神经网络的组合模型,选取2002—2021年中国人均GDP、产业结构、城镇化率、润滑脂产量、陶瓷产量、玻璃产量、空调产量、锂离子电池产量和新能源汽车产量作为需求情景预测的主要驱动变量,对中国2025—2035年碳酸锂需求进行预测,在此基础上提出了针对性的政策建议。结果表明:所选取的驱动变量与碳酸锂需求具有较高的关联性,且组合模型较单一模型预测精度更高。3种情景下2025年、2030年和2035年预测的碳酸锂需求量均值分别为42万t、69万t和103万t。

The inconsistency between the supply and demand of lithium carbonate is becoming increasingly serious. Scientific prediction of the future lithium carbonate demand is of great significance for China’s lithium resource production, import and export arrangements, and national energy policy formulation. Based on a combined model of grey correlation analysis and the ARIMA-GM-BP neural network, data on the driving variables of China’s per capita GDP, industrial structure, urbanization level, grease production, ceramic production, glass production, air conditioning production, lithium-ion battery production, and new energy vehicle production in 2002-2021 were selected to predict China’s lithium carbonate resource demand between 2025 and 2035. The results show that the selected driving variables are highly correlated with China's lithium carbonate resource demand, and the combined model is more accurate than a single model. The predicted average quantity demand for lithium carbonate in 2025, 2030, and 2035 is 0.42 million tons, 0.69 million tons, and 1.03 million tons, respectively. Accordingly, some policy suggestions have been proposed.
