An Analysis on Total Factor Productivity and Influencing Factors of Soybean in China

To investigate the characteristics of total factor productivity and its influencing factors in china’s soybean. Cobb-Douglas production function model is used in this study. The data is based on the period from 1990 to2007, and C-D production function is applied twicely. The results of this study indicate that total factorproductivity grows at 0.42% annually, the changes fluctuate apparently. Through analysis, the pattern ofcultivation, imports and exports policy and technical achievement may contribute to the fluctuation of totalfactor productivity in China’s soybean. Finally, the study proposes some approaches and policy implications so
