摘要
为科学客观地评价企业安全投入效果,提高安全管理水平,以2013—2019年我国采掘业上市企业为样本,建立面板数据多元回归模型,实证分析安全投入、内部控制与企业价值之间的关系,并进一步探讨企业内部控制对安全投入与企业价值关系的调节作用。结果表明:采掘业上市企业安全投入与企业价值呈显著正相关关系;企业的内部控制越好,企业的价值也越高;内部控制在安全投入与企业价值之间发挥调节效应,良好的内部控制可以增强安全投入对企业价值的正向影响。因此,采掘业上市企业不仅要注重安全投入,同时应建立有效的内部控制管理机制,促进企业价值不断提升。
To improve the safety management level of listed extractive enterprises,and clarify the mechanism of safety investment and internal control on enterprise value,based on the existing literature,this paper constructed a research framework of"safety investment-internal control-enterprise value",and established the hypothesis model of their relationship.Firstly,the paper collected and sorted the data of 81 listed enterprises based on the sample of mining industry listed enterprises in our country from 2013 to 2019.Enterprise value,safety investment,internal control,capital structure,and other corresponding measurement indicators were obtained through the Wind database and the DIB Index released by DIB Enterprise Risk Management Technology Co.,Ltd.,and were successively defined as explained variables,explanatory variables,adjusting variables,and control variables.Secondly,the data processing software Stata 16.0 was used for empirical analysis.This paper made descriptive statistics of each variable.Then,the correlation and multicollinearity of enterprise value with safety investment and internal control were tested.After the consistency test was passed,the non-equilibrium panel data were analyzed by multiple regression according to the model.The empirical analysis results show that:safety investment has a significant positive impact on enterprise value;Internal control has a significant positive correlation with enterprise value.Internal control has a moderating effect on the impact of safety investment on enterprise value.On the whole,the higher quality of internal control is more helpful for enterprises to calculate and draw safety production costs according to regulations,improve the safety management level of enterprises,and then improve the enterprise value.Finally,through the robustness test,it is found that the safety investment has a certain lag to the enterprise value.To some extent,the above researches enrich the relevant research from the perspective of safety,and provide decision support for enterprises to establish a perfect internal control system and promote the level of enterprise security management.
