Agricultural technology comes mainly from two aspects, one is the production of new agricultural technology in city, and another is technology transferred to agriculture from non-agricultural sector. This article discusses the relationship and response in the urbanization, non-agricultural technology and agricultural technology changes through the SVAR model.It thinks that not only agricultural technology has lasting power to urbanization, but also has long-term effects on the non-agricultural technology. The short term effects on agricultural technology from China's urbanization is not obvious, but non-agricultural technology’s short-term effects on agricultural technology are obvious. Then, we should play urbanization an important role in increasing agricultural technology, advocate adaptive agricultural technology innovation, and improve the agricultural extension system, accelerating technology transfer from a non-farm sector to the agricultural.This is a way to realize of urban and rural development, improve the quality of urbanization.
