采取随机前沿生产函数超越对数面板模型,对2000～2013年中国北方春玉米区、黄淮海夏玉米区、西南山地玉米区3大优势区玉米种植的技术效率及其影响因素进行分析,并对生物化学型和机械型两种技术的利用效率进行测算。结果表明,3大核心优势区玉米技术效率均呈波动上升趋势,北方春玉米区、黄淮海夏玉米区两个优势区的技术效率要明显高于西南优势区;3大区域生物化学型技术利用效率均高于机械型技术,不同区域变动趋势不同。

By using the method of stochastic frontier analysis(SFA), the technical efficiency and the correspond- ing influential factors of maize production were analyzed in the three predominance-areas of the northern part, the Huang-Huai-Hai plain and the southwestern part. The utilization efficiency of the technologies of biochemical pat- tern and mechanical pattern was also measured. The results showed that, the technical efficiency of maize produc- tion in the three predominance-areas had presented a fluctuated improving trend and in terms of technical efficien- cy, the two predominance-areas of the northern part and the Huang-Huai-Hai Plain was obviously higher than the southwestern predominance-area; the utilization efficiency of biochemical technology of all these three predomi- nance-areas was superior to that of mechanical technical, but the changing trend of these two technologies at differ- ent areas differs.
