摘要
本文采用2005~2013年中国信息技术类上市公司的面板数据,对企业股权结构、价值链属性与技术创新关系进行了实证研究。本文的研究结果支持双重委托代理理论:中国信息技术企业的股权集中度与技术创新之间呈现显著的非线性关系,当第一大股东持股比例在26.56~50.63%之间时,股权集中度对技术创新形成“支持效应”。股权集中度过低或过高都不利企业创新。通过对企业价值链属性的分析结果发现高股权集中度、低股权制衡度的结构安排更有利于研发环节的信息技术企业的技术创新;而低股权集中度、高股权制衡度更利于营运环节的信息技术企业的技术创新。
We investigate the relationship between ownership structure, value chain position and technological innovation using a sample of Chinese information technology companies in the period of 2005-2013.Our results support dual agency theory illustrated by following observations: there is a nonlinear relationship between ownership structure and technological innovation, furthermore Ownership concentration supports technology innovation only when the voting right of largest shareholder is between 26.56% to 50.63%. Higher or lower ownership does no good to firms' innovation; Centralized ownership is more conductive to enterprises' technical innovation in research-based firms, while decentralized ownership benefits operating-based firms.
