Abstract: Since the reform and opening up, the government's leading agricultural technology promotion mode greatly promoted the development of agricultural economy in China. However, with the development of the market-oriented economy, it is difficult for this mode to promote the further development of agriculture in our country. Based on the view of information asymmetry and interactive theory, this paper compares these below three modes which refer to government-leading, dominant enterprise-leading and agricultural cooperatives-leading to find out the pattern and performance of these three leading modes. The available studies have already found out that agricultural cooperatives-leading mode is playing a more important role in the generalizing of agro technique that provides better theoretical basis for solving the current Three Rural.
