近些年来,随着我国证券市场的迅速发展并不断完善,上市公司的融资结构也发生了重大变化,进而影响到了投资规模。从国外来看,对融资结构与投资规模之间的关系的研究已经颇有成效,但是国内对这一方面的研究起步较晚、成果较少。前人的研究主要是利用Logistic回归模型进行分析,但各控制变量间往往存在多重共线性关系,影响到了分析效果。本文借鉴了前人对相关课题的研究成果,主要采用因子分析的研究方法,以融资结构对投资规模的影响作为研究的起点,按照一定的原则选出12个常用的指标,并通过一定的数学方法进行处理,然后采用软件spss16.0中的因子分析法进行分析,得出数学模型。在得出数学模型后,对因子进行命名,为后人进行相关研究提供借鉴。
In recent years, with the rapid development of China’s securities market and continuous improvement, the financing structure of listed companies has undergone major changes, thus affecting the scale of investment. From a foreign perspective, the research on the relationship between the structure of financing and the scale of investment has been quite fruitful, but the domestic research on this aspect started later with less result. The previous studies mainly use the Logistic regression model to analyze, but there is often multiple collinearity between the control variables, which affects the analysis results. This paper draws on the previous research results of related topics, mainly using factor analysis research methods, the financing structure of the scale of investment as a starting point for the study, according to certain principles selected 12 commonly used indicators, and through a certain mathematical Method for processing, and then use the software analysis of factor analysis in spss16.0 analysis, the mathematical model. After the mathematical model is drawn, the factors are named, which can provide reference for future generations to carry out relevant research.
