Abstract: “Internet ” agricultural machinery will help to change and innovate the production method, development pattern, industrial structure, and organization mode of agricultural machinery industry. Based on the basic theory of “internet ” and industrial convergence, this paper defines scientifically the basic concepts and connotations of “internet ” agricultural machinery, analyzes the key links and the main content of “Internet ” agricultural machinery chain, and discusses the convergence mode and the bottleneck of “Internet ” agricultural machinery. Results show that “Internet ”agricultural machinery chain contains three links, including high-end research, product development and introduction, and marketing and services. And the integration method and means rely on the ways of technology resources convergence, sales channel integration, agricultural service model and management model innovation to form new pattern and format of modern agricultural field industrial chain, such as distributed network collaborative research and development, agricultural machinery E-commerce promotion, data on-line services and cloud-based ecological management. In the process of integration, “Internet ” agricultural machinery still has some major problems, including the lack of core technologies and standards, short of agricultural management capacity, and low level of industrial development. In addition, this paper suggests to speed up the development of “Internet ” agricultural machinery industry from the establishment of public R&D platform, and to strengthen farmers training, agricultural agronomic integration, and the purchase of agricultural subsidies.
