On the basis of document research, we summed up factors of technical demand of commercial paddy farmers to four aspects: individual characteristics of farmers, natural endowment of resources, factors related to risks, and information factor. Then, we put forward relevant hypotheses. From survey results of 241 farmer households in 4 southwestern provinces (regions), by the binary logistic regression analysis method, we empirically studied influences of the above four factors on technical demand of commercial paddy farmers. Results show that commercial paddy farmers like simple and high yield cultivation technique best, while individual characteristics of farmers, natural endowment of resources, factors related to risks, and information factors are major factors influencing different agricultural technical demand of commercial paddy farmers.
