摘要
以2013年第一季度至2016年第四季度A股上市的石油企业为样本,采用多元回归模型研究了国际油价不确定性对我国石油企业投资的影响。结果显示:国际油价不确定性对我国石油企业投资存在显著的负向影响,在分组研究中发现,国际油价不确定性对规模较大的石油企业与非国有石油企业的投资存在显著的抑制作用,而对规模相对较小的石油企业及国有石油企业的投资存在非显著的抑制作用。最后提出了改进我国石油企业投资策略的具体建议。
Taking oil companies listed on the A-shares from the first quarter of 2013 to the fourth quarter of 2016 as a sample,this article uses a multiple regression model to study the impact of international oil prices uncertainty on the investment of Chinese oil companies. The results of the study show that the uncertainty of international oil prices has a significant negative impact on the investment of China＇s oil companies. In the group study,it was discovered that the uncertainty of international oil prices has significantly inhibited the investment of large-scale oil companies and non-state-owned oil companies,but has a non-significant inhibitory effect on the investment of small-scale oil companies and state-owned oil companies. Finally,this article puts forward some suggestions for the investment strategy of oil enterprises.
