| 摘 要： | 采用主成分分析和多元线性回归的方法，通过构建甘肃省农业投入产出的指标体系，建立农业投入产出效率的计量模型，研究甘肃省农业投入产出之间的相关关系和联动效应。研究结果表明：甘肃省农业资本投入对产出的贡献度最高，其次为技术投入，农村劳动力过剩成为制约甘肃省农业发展的瓶颈因素。

| Abstract: | Applying the methods of principal component analysis and multiple terms linear regression, establishing the index system of the agricultural input - output efficiency in GanSu Province and setting up agricultural input - output efficiency calculating model, this paper studies the correlation and linkage effect of agricultural input and output in GanSu Province. The study shows that agricultural capital investment in GanSu province contributes most to the output, next about technical input. The surfeit of rural labor force becomes a restrictive factor for restraining agricultural development in GanSu province. |
