Comparing The Effect Of Explain Variable Combinations On Multiple Corporate Goals

From the perspective of multiple linear regression analysis,this paper tries to understand the meaning and measurement index of regression effects firstly,and apply the parameter constraint test to the comparison of the regression effect.Then it is extended to multivariate regressions,deducing the hypothesis test form of comparing regression effects at different levels.at the same time,we apply it to the study of corporate performance and influencing factors,aiming to compare the effects of corporate performance influencing factors.Based on the summary of related literature and theories,this paper selects five corporate performance indicators as the dependent variables from two aspects of profitability and development capacity,such as total asset net profit rate,net capital yield,operating profit,basic earnings per share,and operating profit growth rate.Then we choose some influencing factor indicators as the independent variables with the corporate performance indicators to establish multivariate regression models.Next we compare the effects of corporate performance influencing factors by regression statistical test,which helps to grasp key factors and has important practical significance.This paper makes an empirical analysis of the financial data of manufacturing listed companies from 2013 to 2016,The main conclusions are as follows:first of all,for the first four corporate performance indicators,each influencing factor variable has the same direction effect.The negative effect of R&D investment on these four indicators is statistically higher than the positive effect of human capital investment;R&D investment has the strongest effect on operating profit,and there is no significant difference between the effect on total assets net profit rate and basic earnings per share,which has the weakest effect on net capital return rate.At the same time,we can find that R&D expenses,and R&D input intensity have positive and negative effects on operating profit growth respectively,but there is no significant difference in effect size;Total asset turnover has positive marginal contribution to five corporate performance indicators.However,the liquidity turnover rate only has a positive marginal contribution to the operating profit growth rate;The asset-liability ratio has a negative effect on the five corporate performance indicators,among which the impact on the total asset net profit rate is the strongest.
