摘　　要：为深入研究中国工业品价格传导机制,选择进口商品、原材料购进、工业品出厂、商品零售、居民消费等6种价格指数代表工业产品价格传导链条,借助符号动力学方法建立了中国工业产品价格同步传导复杂网络。研究了该网络度分布、加权集聚系数、平均最短路径长度、中介中心性以及社团结构等网络拓扑性质。以广州市汽车行业为例,发现价格传导动力学性质与中国工业产品价格基本相同,为开展价格预测与调控提供了新视角和途径。In order to study the price synchronization transmission of industrial products in China, 6 price indexes are selected as the price conduction chain of industrial products. The price transmission synchronization complex networks in China are established by using symbolic dynamics. Then, with the price conduction of automotive industry in Guangzhou as an example, the degree of distribution, weighted clustering coefficient, average shortest path length, and community structure of the network are analyzed. It is found that they share basically the same price conduction dynamics nature. In conclusion, a new perspective and approach of forecasting and controlling price volatility is provided.
