对C-D生产函数法、增长速度方程法(Solow余值法)、全要素生产率指数法(TFP)、固定替代弹性生产函数(CES)、边界生产函数法、数据包络分析法(DEA)等我国农业科技进步贡献率的测算方法进行了综述,并进行了比较与评价,认为TFP指数法中的Translog指数法能够区分要素数量和质量分别对产出的贡献,可推广应用。并指出,在要素投入变量选取上要全面考虑农、林、牧、渔四业,不能偏颇于种植业。
對C-D生產函數法、增長速度方程法(Solow餘值法)、全要素生產率指數法(TFP)、固定替代彈性生產函數(CES)、邊界生產函數法、數據包絡分析法(DEA)等我國農業科技進步貢獻率的測算方法進行瞭綜述,併進行瞭比較與評價,認為TFP指數法中的Translog指數法能夠區分要素數量和質量分彆對產齣的貢獻,可推廣應用。併指齣,在要素投入變量選取上要全麵攷慮農、林、牧、漁四業,不能偏頗于種植業。

In this paper,the calculation methods of agricultural science and technology progress contribution rate are reviewed,such as C-D production function method,Solow residual method,total factor productivity index method,constant elasticity of substitution production function method,boundary production function method,data envelopment analysis method and so on. Then it is also provided the comparison and evaluation on them. The conclusion is Trans-log index method which belongs to the TFP index method can distinguish the contribution to the output between quantity and quality of factors,so it could be widely applied,and noted that we should take a full accounting of agriculture,forestry,animal husbandry and fishery industry while selecting variables in factor input,not biased in farming.
