China's rapid economic growth is largely dependent on the high consumption of resources, especially the agricultural which is still in the extensive growth stage. As—crisis era coming it will be difficult to continue. The growth mode transformation depends on sci-tech progress. Agricultural extension is the basic means to converted potential productivity to actual productivity. It also promotes the conversion between agricultural technological innovation and economic benefit. In china a comparatively perfect agricultural extension system from centfra to township plays an irreplaceable role in promoting the development of agricultural.Under new situation, some provinces and cities make active exploration on new extension patterns suitable for agricultural and rural economic development, and many new types of agricultural extension patterns develop rapidly. The contribution rate of agricultural science and technology progress from 2001 to 2008 in Beijing is 73.7%. The rate not only reflects the high level of agricultural science and technology in Beijing, but also indicates that the perfect agricultural extension system makes great contributions to agricultural scientific achievements transform. Therefore, the summary and analysis of the experience of the agricultural extension in Beijing is of important significance for the development of the agricultural extension in china. Based on public goods theory, innovation diffusion theory and system theory, this paper analyzes the main factors about the agricultural extension. And make ecific analysis on the typical models of Beijing. Finally it concludes the development trend of agricultural extension is that gradually expanding the content of extension services, more reflecting the wishes of the farmers, exploring new ways of agricultural extension, focus on the training of "Local Experts".Although the agricultural extension in Beijing has made great contributions for agricultural and rural economic development, but there are still many problems. For example, the function of the orientation is unclear, effective supply of science and technology is inadequate. Through the analysis of agricultural extension system of America, Canada, German, Japan and other countries, combined with the problems of agricultural scientific achievements transform in Beijing. We raise some suggestions:Re-establish the extension organizations and build a flexible system of agricultural extension. Improve the method of extension and build a reasonable combination of agricultural research, education, and extension to promote the development of different agricultural extension forms. Build multi-channel investment mechanisms and increase financial support from government.
