摘要
为深入研究中国农产品价格波动和传导机制,选择籼稻、粳稻、小麦、玉米和大豆等5种大宗农产品为代表,借助符号动力学方法建立了农产品价格同步传导复杂网络模型。研究了该网络波动幅度和强度分布、聚集系数、强度与聚集系数相关性等网络拓扑性质,并以中国1997年4月到2012年12月期间相关价格数据进行了实证分析。最后提出了新形势下中国农产品价格调控的对策及建议。
In order to further research on agricultural price volatility and the transmission in our country, an agricultural prices synchronous transmission complex network model is built based on the method of symbolic dynamics, which Nonglutinous rice, Japonica rice, Wheat, Maize and Soybean are selected as 5 kinds of commodities in bulk farm-products. Network fluctuation, strength distribution, cluster coefficient and the dependency between strength and cluster coeffi- cient are studied in our paper. And empirical analysis is given based on price data during April 1997 to December 2012 in our country. At last, countermeasures and suggestions about price adjustment and control in our country are proposed.
