摘要
对企业技术创新过程的效益评价模型（１）参数估计的三种方法：多元线性回归、岭估计和主成份分析的适用性进行了比较分析，为该模型的适应范围及对建模中的多重共线性问题的解决提供了理论支持，并给出实际应用案例．
This paper deals the comparative analysis on the application of the three methods in parameter estimation on benefit evaluation model(1) in the process of enterprise technological innovation: multiple linear regression, edge of estimation, principal components analysis, which provides a theoretical basis with the scope of application for the model and the possible solution to multi collinearity in modelling as well as presents a practical case.
