机电井地下水灌溉系统分析及其技术效率——河北省机电井地下水灌溉系统的实证研究

Analysis of tubewell groundwater irrigation system and its technical efficiency

  • 摘要: 基于对河北省机电井系统的实地调查,建立了机电井系统供水量的随机边界生产函数模型.研究结果表明,所有制、治理机制和系统规模等是影响机电井系统技术效率的主要因素,非集体所有制的技术效率明显优于集体所有制.同时对如何引导灌溉系统的持续高效发展提出了一些政策建议.

     

    Abstract: Based on the field survey of tubewells in Hebei Province,a stochastic water frontier production model of tubewells is established. The research results show that the ownership,the management mechanisms and the scale are all statistically significant influence factors on tubewell technical efficiency,and the technical efficiency of non-collective ownership is higher than that of collective ownership1 Based on this study,several policy suggestions on efficient and sustainable development of irrigation systems are provided.
