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。
農業科技推廣本質上就是農業新技術擴散的過程。為此，把農業科技推廣繫統視為一種複雜網絡，主要利用複雜網絡中的信息傳播理論構建農業科技推廣數學模型，研究農業新技術的擴散動力學行為。從模型可知：影響農業新技術傳播的關鍵因素是傳播彊度；技術已知者數目越多，則技術傳播的越快；要重視科研等關鍵節點建設。

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 ag -ricultural technology .This model shows that :the communication intensity is the most important factor which affects agri-cultural 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 .
