摘要

本文的目的是研究石油价格变化与我国石油矿业企业盈利能力之间的关系。本文收集了2011 - 2020年中国石油开采行业及上市公司的相关数据,运用标准价值权重法和回归分析法进行实证研究。研究结果表明:(1)2011 - 2020年,国际油价年均跌幅为6.71%,显著削弱了中国石油开采行业上市公司的盈利能力。(2) 2011 - 2020年,中国汽油价格年均降幅为2.61%。然而,由于中国政府实施“最低限价”政策,石油开采行业上市公司的盈利能力不但没有下降,反而增加了。(3) 2011 - 2020年,中国石油开采行业上市公司内部控制水平持续下降,且与盈利能力呈显著负相关。(4)中国石油勘探行业上市公司坚持可持续发展理念,重视科技投入,有效经营资产,增加现金流,控制成本。这些措施大大提高了企业的盈利能力。

Study on Oil Price Change, Internal Regulation and Profitability Index -- Taking Oil Exploitation Industry of China as an Example
The objective of this paper is to study the relationship between the change of oil price and the profitability of Chinese oil mining enterprises. This paper collects the relevant data of China’s oil exploitation industry and listed companies from 2011 to 2020, and makes an empirical study by using the standard value weight method and regression analysis method. The conclusions are as follows: (1) from 2011 to 2020, the average annual decline of international oil price is 6.71%, which significantly weakened the profitability of Listed Companies in China’s oil exploitation industry. (2) From 2011 to 2020, the average annual decline of gasoline prices in China is 2.61%. However, due to the implementation of the “minimum price” policy by the Chinese government, the profitability of Listed Companies in the oil exploitation industry has not decreased, but increased. (3) From 2011 to 2020, the internal control level of Listed Companies in China’s oil exploitation industry continued to decline, which was significantly negatively correlated with profitability. (4) Listed companies in China’s petroleum exploration industry adhere to the concept of sustainable development, pay attention to scientific and technological investment, effectively operate assets, increase cash flow and control costs. These measures have significantly improved the profitability of enterprises.
