水稻种植投入产出状况分析

Analysis on Input-Output in Rice Cultivation

[目的]基于CD函数对水稻种植投入产出状况进行分析。[方法]以水稻种植户为研究对象,基于要素投入角度,运用柯布道格拉斯生产函数对水稻生产的投入产出情况进行计量分析。[结果]在同等技术条件下,考虑到劳动力投入与资本投入的替代效应,农户增加劳动力投入对水稻每667 m2产量的影响为负值,在此基础上提出了2条促进水稻种植户剩余劳动力转移和确保水稻生产性资金供给的政策建议。[结论]该研究为实现水稻生产资源的合理配置奠定了基础。

[ Objective ] To analyze the input and output in rice cuhivation based on CD function. [ Method ] Based on the input factors, Cobb- Douglas production （CD） function was used to do the quantitative analysis on the input-output in rice production with rice growers as the ob- jective. [ Result] Considering the substitution effect of labor input and capital input, under the same technical conditions, the effect of in- creasing labor input on the rice production in per 667 m2 was negative, based on which two pieces of policy advice were put forward to promote the transfer of surplus labor force of flee growers and ensure the capital supply for rice production. [ Conclusion] This study laid the foundation for the realization of reasonable allocation of rice production resources.
