农业产业化地区玉米生产技术效率研究

Study on the Technical Efficiency of Maize Production in the Agricultural Industrialization Area

运用两阶段双重自助抽样DEA方法研究农业产业化地区玉米生产技术效率,研究结果表明,72.6%的农户玉米生产技术效率值处于无效区间,在影响农户玉米生产技术效率的因素中,农户投资规模对玉米生产技术效率具有负效应,表明农户玉米生产投资已进入无效率区间,进一步提高投资规模,已不能提升农户玉米生产技术效率。此外,政府给予玉米种植补贴对玉米生产技术效率的提高并不显著。

Based on the two-stage double bootstrap DEA method,this paper used the micro-survey data ofmaize growers in the typical agricultural industrialization area to estimate the bias-corrected robust DEA efficiencyscore of farmer’s maize production,and analyzed the specific factors affecting its technical efficiency.It was foundthat the farmer’s investment scale had a negative impact on the efficiency of maize production technical efficiency,and the effect of government subsidies to maize planting to improve the technical efficiency of maize production wasnot significant.
