Use the Grey system theory to analyze the influencing factors of the total power demand of China's Agriculture-machinery and predict the development trend of the next 6 years. The results follow: at the present stage, the total level of China's Agriculture-machinery and mechanization has a great impact on the total Agriculture-mechanization income. The development of China's large-scale Agriculture-machinery industry is also an “extensive” interest-driven model and will be improved to some extent in the next 5-6 years. The Agriculture-machinery total number, Agriculture-machinery power distribution is not scientific, the scale operation problem of blind pursuit. And the article pointed out that the current changes in China agricultural enterprises are the pursuit of profits. In the current situation, investment in technology R&D funds and other recommendations should be strengthened to improve competition in the middle and low-end market.
