摘要随着我国经济的迅速发展，上市公司也日益增加。影响上市公司投资收益的因素有许 多。本文着重讨论上市公司所属行业对投资收益的影响。以不同行业对应下的股票投资 收益作为因变量，行业作为因子。运用方差分析法对因变量与因子之间的显著性关系进 行分析。首先运用 Kolmogorov-Smirnov 法对收集的数据进行正态性检验，然后运用 Hartley 检验进行方差齐性检验，最后运用方差分析法检验行业对投资收益是否具有显著 性影响。结果表明，以一年为投资周期，行业对投资收益具有显著性的影响作用；以五 年为投资周期，行业对投资收益的影响不显著；以十年为投资周期，行业对投资收益几 乎没有影响。最后对实证结果进行了分析。76137

Title Effect of Listed companies by sector

 Analysis of return on investment

Abstract

With the rapid development of our country's economy,the listing Corporation is also increasing。There are many factors that affect the investment income of listing Corporation。This paper focuses on the impact of listing Corporation's industry on investment income。In different sectors of the corresponding stock investment income as the dependent variable,the industry as a factor。Using the variance analysis method to analyze the significant relationship between the factors and the dependent variables。First of all,the use of the Kolmogorov Smirnov method to collect data is the normality test,then using Hartley test for homogeneity of variance test,finally,using the analysis of variance test industry return on investment is significantly affected。The results show that a year investment cycle,industry of investment income has significant influence;to five years for the investment cycle,the impact of the industry on the investment income is not significant;in ten years for the investment cycle,industry of investment income almost had no effect on。Finally,the empirical results are analyzed。
