我国电力企业技术效率评价及影响因素分析

利用SFA模型对我国15家电力企业2003-2009年的技术效率进行评价。研究发现:我国电力企业技术效率呈逐年递增的趋势,但增长速度逐年下降,技术水平和管理效率是制约技术效率提升的两大因素。电力企业之间技术效率差异较小,弱化了企业创新的动力。影响电力企业技术效率的因素主要包括内部交易成本、人力资本投资和专用性资本投资,其中影响我国电力企业内部交易成本的因素包括组织结构、业务流程和员工激励机制,人力资本投资对技术效率的影响可以从内部协同效应和协调成本的角度来解释。

The Technical Efficiency Estimates of Chinese Power Enterprises and the Analysis of Influential Factors

This paper uses SFA model to estimate the technical efficiency of 15 Chinese power enterprises,based on the data from 2003 to 2009.The study reveals that the technical efficiency of 15 Chinese power enterprises has been increasing every year,while the speed of increasing has been slowing down year by year.The main restraint factors include technology and management efficiency.The insignificant differences on technical efficiency among Chinese power enterprises weaken their motion of innovation.The factors that affect the technical efficiency of Chinese power enterprises include internal transaction cost,human capital investment and specific capital investment.What affect internal transaction cost consist of organization structure,work flow and incentive mechanism.The effect of human capital investment can be explained from the point of view of internal synergy effects and coordination cost.
