A comparative study on the allocation of production factors of citrus in the U.S.A and China

Adopt American citrus for contrasting, use regression model and weighting least square technology estimation for fitting the elasticity of the costs of labor input, chemical fertilizers, planting protection as well as the organic fertilizers of unit output of Chinese citrus, and then the optimum allocation of production factors and the corresponding optimum unit output of American citrus and Chinese citrus are figured out. The result indicates: Firstly, in comparison with that of American citrus, the factor allocation of Chinese citrus is much unreasonable; Secondly, the input of chemical fertilizers in China is found too deficient to meet the need of optimum allocation; Thirdly, increasing labor input is the best measure to optimize current resources allocations of Chinese citrus; Finally, the contribution rate of technology progress of Chinese citrus (47%) is much lower than that of American citrus (77.85%). At last, some recommendations for government are provided to promote Chinese citrus development.
