【摘要】 为定量分析农业机械化在农业产出中的贡献份额,利用柯布-道格拉斯(Cobb-Douglas)生产函数和多元回归分析法,建立了金华市1986~2005年农业生产函数模型。据此测得金华市在此期间农业机械化对增加农业产出的年均贡献率为15.33%,并呈逐渐增长趋势。对影响农业机械化贡献率的因素分析表明,增加农业机械投入和提高机械化作业水平对提高农业机械化贡献率仍具有较大的潜力。更多还原

【Abstract】 In order to analyzing agricultural machinery’s contribution to agricultural output growth , agriculture production function was presented in Jinhua city by Cobb-Douglas model and linear regression optimization and statistic data from 1989 to 2005, agricultural machinery’s contribution ration to the agricultural output growth in area mentioned was estimated by means of production function above. Calculating results showed that agricultural machinery’s contribution ration to the agricultural output growth was 15.33% in Jinhua city, then increasing of investment in agricultural machinery and raise of mechanization level of farm work will further enhance agricultural machinery’s contribution to agricultural output growth.更多还原
