提高玉米生产效率对全球粮食安全和农产品有效供给具有重要意义。本研究基于381户农户的调查数据，采用随机前沿分析法估算效率值，并对华北平原衡水地区玉米生产技术效率的影响因素进行实证分析。首先，人们发现较高的成本与广泛使用施肥、施用农药和灌溉的生产方法有关。②灌溉成本与玉米产量呈倒u型关系；当灌溉成本约为938元/公顷时，玉米单产最优。肥料成本与玉米产量之间也存在倒u型关系，当肥料成本为2547元/公顷时，玉米产量的技术效率损失最小。此外，低效率影响因子模型的结果表明，温度和湿度都与玉米生产的低效率呈正相关。研究结果可为提高中国北方或全球干旱半干旱地区玉米生产效率提供实证支持。
Improving the efficiency of maize production is of great significance for global food security and the effective supply of agricultural products. Based on the survey data of 381 rural households, this study uses a stochastic frontier analysis to estimate the efficiency value and empirically analyze the factors affecting the technology efficiency of maize production in the Hengshui area of the North China Plain. First, higher costs were found to be related to extensive production methods of fertilization, pesticide application, and irrigation. Second, the results showed that there was an inverted U-shaped relationship between the irrigation cost and maize output. Specifically, when the irrigation cost was about 938 yuan/hectare, the maize output per unit area was optimal. Third, there was also an inverted U-shaped relationship between the fertilizer cost and maize output, and the loss of technical efficiency of maize output was minimal when the fertilizer cost is 2547 yuan/hectare. In addition, the findings of the inefficiency influencing factor model suggested that temperature and humidity were all positively associated with the non-efficiency of maize production. These findings can provide empirical support for improving the efficiency of maize production in North China or arid and semi-arid regions around the world.
