Economic Security Warning of Lithium Carbonate in China
In order to further study the economic security of lithium carbonate,an evaluation index system was constructed for the economic security of lithium carbonate in China from four dimensions:resource en-dowment,import dependence,acquisition cost and geopolitics.The constant weight and variable weight models were used to evaluate the economic security of lithium carbonate in China from 2009 to 2020.The GM(1,1)model and BP neural network model were used to study the economic security of lithium carbon-ate in China from 2021 to 2035.The results show that:(1)Import concentration,external dependence and transportation risk are the main factors affecting the economic security of lithium carbonate;(2)From 2009 to 2020,the economic safety of lithium carbonate in China showed a downward trend,and the safety level fluctuated from yellow-basic safety level to orange-unsafe level,The resource endowment the import dependence are the main reasons for the low level of resource security;(3)From 2020 to 2035,the eco-nomic security score of China's lithium carbonate continued to decline.Except for 2021 and 2026,which were in the yellow-basic safety level,the rest of the years were in the orange-unsafe level.
