innovation diffusion theory

The paper analyzes the frame structure theory, the communication theory, the behavior alternation theory in products, and theory of the agricultural innovation and technology diffusion.

农业技术扩散的理论主要有框架理论、沟通理论、农户行为改变理论和技术创新扩散理论。

In China, however, the study on innovation diffusion models and their applications is still at an early stage; and it is far behind oversea countries, whether in the theory or in the practice.

然而，我国对扩散模型及其应用的研究尚处于初始阶段，无论是理论研究还是实践应用都与国外先进国家相距甚远。
