摘要
本研究通过对山东省无棣县100户甜高粱种植户进行调查,并系统研究了在盐碱地种植甜高粱的成本和收益,通过构建Cobb-Douglas生产函数模型,进行投入-产出分析,结论如下:种植面积和科技投入是增收的重要因素,人力投入对收益的影响不显著。应进一步提高技术水平,适当地扩大种植规模。
Through investigating 100 Sweet sorghum growers in Shandong Wudi county, this study made systematic study of the costs and benefits of sweet sorghum cultivating in saline soil, conducted the input-output analysis by building Cobb-Douglas production function model, and got the conclusions that the acreage and science and technology investment is an important factor for the increase income, the impact of human input on the income was not significant. We should further improve the technical level and expand the scale of planting appropriately.
