中国玉米核心优势区技术效率及技术进步模式研究——基于2000-2013年的省际面板数据
本文采取随机前沿生产函数超越对数面板模型,对2000-2013年的北方、黄淮海和西南三大优势区玉米种植的技术效率及其影响因素进行了分析,并对生物化学型和机械型两种技术的利用效率进行了测算。结果表明：三大核心优势区玉米技术效率均呈波动上升趋势,北方和黄淮海两个优势区的技术效率要明显高于西南优势区；三大区域生物化学型技术利用效率均高于机械型技术,但不同区域变动趋势不同。
英文摘要:
By using the method of Stochastic Frontier Analysis (SFA), this paper has analyzed the technical efficiency and the corresponding influential factors of maize production in the three predominance-areas of the northern part, the Huang-Huai-Hai Plain and the southwestern part. The paper has also measured the utilization efficiency of the technologies of biochemical pattern and mechanical pattern. Two points have been shown by the results: the technical efficiency of maize production in the three predominance-areas has presented a fluctuated improving trend and in terms of technical efficiency, the two predominance-areas of the northern part and the Huang-Huai-Hai Plain is obviously higher than the southwestern predominance-area; the utilization efficiency of biochemical technology of all these three predominance-areas is superior to that of mechanical technical, but the changing trend of these two technologies at different areas differs.
