摘　　要：解构中国与周边国家盐业和盐化工业贸易网络变化与驱动机制对稳定贸易结构具有重要意义。基于中国与周边国家盐业和盐化工贸易数据,利用社会网络方法、可视化分析工具以及地理加权回归(GWR)模型,研究中国与周边国家盐业和盐化工业贸易网络时空演化特征与驱动机制。结果表明:(1)2000-2018年各国间贸易网络结构凝聚力不断提升、网络效率逐步提高。(2)贸易网络呈现多等级轴—辐结构;子群格局地理集聚特征明显,中国在子群内部保持绝对核心地位,但地位优势和关联程度均呈下降趋势;度中心性稳定增长,各国贸易多样化发展。(3)经济规模、工业规模、人口规模和科技进步对盐业和盐化工业贸易都起到正向驱动作用,驱动程度依次为经济规模、工业规模、人口规模、科技进步。It is of great significance to deconstruct the change and driving mechanism of trade network of salt industry and salt chemical industry between China and neighboring countries. Based on the data of salt industry and salt chemical trade between China and its neighboring countries, this article uses the methods of social network, visual analysis and geographically weighted regression(GWR) to analyze the spatio-temporal evolution characteristics and driving mechanism of trade network of salt industry and salt chemical industry between China and its neighboring countries. The results show that: 1) From 2000 to 2018,the structural cohesion and network efficiency of trade network among countries have been continuously improved. 2) The trade network presents a multilevel hub-and-spoke structure;The geographical agglomeration of the subgroup pattern is obvious. China maintains the absolute core position in the subgroup,but its status advantage and association degree are both decreasing. The degree of centrality has steadily increased, and trade among countries is diversified. 3) Economic scale, industrial scale, population scale and scientific and technological progress have a positive driving effect on salt industry and salt chemical industry trade. The ranking of driving degree is economic scale, industrial scale, population scale and scientific and technological progress.
