行业投入产出技术系数与行业获利性波动识别

Input-Output Technical Coefficient and Identification of Time-Variation in Industry Profitability

企业经营环境外部系统因素的不确定性是影响企业所有者与经营者之间委托代理问题解决的主要因素,目前还没有文献系统建立企业经营环境信息的识别方法。本文利用技术效率评价中的理论来研究企业经营环境信息的识别问题。基于(k,y)空间的生产可能集与技术效率发展了描述不同行业投入产出差别的技术系数,给出行业获利性波动的时序识别方法。这些方法对弱化企业所有者与经营者之间信息非对称程度,解决二者之间的委托代理问题提供了一个有效途径。

The ambiguity of circumstance systematic factors outside firms is the main factor affecting the solutaon to the principal-agent problem between firm holders and managers, but until now there is scarcely method directly identifying operational circumstance information. In this paper, the theory of technical evaluation is used to establish methods for of identifying firm circumstance information. An extended industry input-output technical coefficient and a method of identifying industry profitability variation are given based on production technology and technical efficiency in （k , y） space. With such methods, information asymmetry between firm holders and managers can be reduced and the principal-agent problem can be solved more effectively.
