摘  要:
农业科技推广本质上就是农业新技术扩散的过程。为此,把农业科技推广系统视为一种复杂网络,主要利用复杂网络中的信息传播理论构建农业科技推广数学模型,研究农业新技术的扩散动力学行为。从模型可知:影响农业新技术传播的关键因素是传播强度;技术已知者数目越多,则技术传播的越快;要重视科研等关键节点建设。

摘  要:
Agricultural machinery extension is actually a process of technology diffusion,which is viewed as one type of complex networks in this study. In this paper,the information communication theory on complex networks is applied to develop a dynamics model of agricultural machinery extension for understanding the dynamic diffusion behavior of new agricultural technology. This model shows that : the communication intensity is the most important factor which affects agricultural technology extension; the more the quantity of the acquired,the fast technology communication; we should pay more attention to the key node such as research and development institutions.
