制造企业信息化对产出贡献的实证研究

An Empirical Study on the Contribution of Informatization to Output in Manufacturing Enterprise

在柯布-道格拉斯生产函数基础上,构建基于信息化投入的生产函数模型,以2004—2006年54家福建省电子电气制造企业信息化数据为样本,运用面板数据分析的方法来测算信息化对产出的贡献系数。研究表明,信息化投入对电子电气企业产出有显著贡献。信息化对产出的贡献不仅取决于信息化的投入,还取决于企业规模、是否设立专门信息化管理机构等因素。

Based on C-D production function, this study set up a production function model about information input, and then took 20（M--2006 information data from 54 electrical and electronic enterprises in Fujian province as sample, applied the method of panel data analysis to calculate the contribution coefficient of informatization to output. Its result shows that the information input contribution to the electronic and electric enterprises was significant, and, the informatization contribution to output not only depends on information input, but also on enterprise scale, on that whether a manufacturer has its special information management organization, and etc.
