海南农垦2002～2003年度干胶生产影响因素实证分析

在分析农业生产函数原理和应用基础上,选用Cobb Douglas生产函数,引入分别反映自然、技术、物质投入的10个影响海南农垦干胶产量的因素,拟合生产函数模型,并应用SPSS软件对各影响因素进行了显著性分析,得出结论为:单位面积平均开割株数,年均干含,单位面积年有机肥施用量,胶工人数对海南农垦干胶产量具有显著的正效应影响,年割刀数和单位面积年压青有显著的负效应影响,其他因素为不显著因素。分析可能造成这种结果的原因,并提出对策。

Analysis on Factors Affecting Outputs of Solid Elastomer of Hainan Stated Farms

The thesis chooses Cobb-Douglas production function and selects ten factors influencing the outputs of solid elastomer of Hainan Stated Farms to form production model.Analyze all the selected factors using the statistic software SPSS.It can be concluded from the analysis that four factors including average plants per hm~2,average containment of one year,the amounts of using organic fertilizer and the numbers of workers have remarkably positive effect on the output of solid elastomer,while two factors including the number of cuts and weight of the grass per hm~2 have remarkably negative effect on it.The other factors show no remarkability.The cause that leads to the result are crackled down and countermeasures are provided.
