Abstract: According to the complex network theory, this paper establishes a complex network model of lithium carbonate global trading, uses lithium carbonate global trading data of UNcomtrade database 20052014 to calculate the degree, weighted degree, clustering coefficient, and modularity, trading group model degree & group change of China’s lithium carbonate in global trading network, with results showing rising trading partners, ranking No.2 in holding international trading relation numbers, which diversifies import and export. China keeps a close and stable relation with partners. Among the entire complex international trading network of lithium carbonate, China has a higher control rights but a descending controlling ability.

摘要： 根据复杂网络理论，构建碳酸锂国际贸易复杂网络模型，利用UNcomtrade 数据库中2005—2014年碳酸锂国际贸易数据，计算得出中国在碳酸锂国际贸易网络中的度、加权度、聚类系数、中间中心度以及所在贸易集团模块度和集团变化情况。结果表明：中国在碳酸锂国际贸易网络中，贸易伙伴不断增多，在拥有国际贸易关系数目方面已经处于世界第二位，进出口均向多元化方向发展。中国与其国际贸易伙伴关系较为密切，且贸易关系稳定性较高。在整个碳酸锂国际贸易复杂网络中，中国的控制权较高，但其控制能力有减弱的趋势。中国所处的国际贸易集团正在发生变化。
