Abstract: The restriction of resources and environment in the process of development in our country is becoming more and more intensive, green technology has become the key to solve the coordinated development between environment and economy. Therefore, green technology and general technology should be discriminated, a nonlinear Cobb Douglas production function model of green technological innovation and economic growth with lag period is proposed. By testing the green technology innovation performance, whether the economic interest has become an effective driving force on green technology diffusion can be analyzed. Based on the green technology innovation and economic growth data in China's during 1991-2010, the fixed effect panel data model is used for empirical analysis. The results reveal the existence of "U"-type relationship between green technological innovation and economic growth in China. Besides, the turning point of the negative effect of China's green technology innovation to economic growth can be calculated, thus, the turning point of different regions can be compared, it shows that the "U"-type relationship appears first in eastern area of, followed by the central region, then the western region.
