Research on Classification Environment Technology Diffusion of Occupational Tobacco Growers

With the technology diffusion model, time path function is deduced. Through the depicting of function graphic, we can find it is S-shaped curve. The results show that the internal and external factor of different parts, and the differences of the total number of "potential adopters" lead to the differences of time path function of classification environment technology diffusion of occupational tobacco growers in different areas, and the differences in different leaf tobacco production areas when marketing the technology.
