| Abstract: | At present, it was used elastic coefficients of all kinds of input factors as constants to appraise the contributive ratio of agricultural mechanization by C-D productive function. On the foundation of researches, the paper gives methods to appraise the contributive ratio of agricultural mechanization under states that elastic coefficients of all kinds of input factors are changed with time, and relevant appraising model was constructed. |
