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。
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 ownership .
