浙江省农业机械化对农业产出贡献率的测算研究

Study on Agricultural Machinery's Contribution Ration to the Agricultural Output Growth in Zhejiang Province

根据统计数据,利用柯布—道格拉斯(Cobb-Douglas)生产函数模型法和多元回归分析法,建立了浙江省1991～2004年农业生产函数模型。据此测得浙江省同期农业机械化对农业产出的年均贡献率12.43%,并分析了农业机械化对农业产出的影响作用,结果表明增加农业机械投入和提高农业机械化水平对浙江省农业产出增长的贡献仍具有较大的潜力。

Agriculture production function was presented in Zhejiang province by Cobb-Douglas production function and linear regression optimization and statistic data from 1991 to 2004, 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 12.43% in Zhejiang province, then increasing of investment in agricultural machinery and raise of agricultural mechanization development level will further enhance agricultural machinery＇s contribution to agricultural output growth.
