BP神经网络视角下我国油企技术创新效率分析

Analysis of Technical Innovation Efficiency of China’s Petroleum Enterprises from the Perspective of BP Neural Network

改革开放以来我国经济得到飞速发展,油气需求量不断攀升,国内产能无法满足消费需求。截至2018年,我国石油对外依存度已逼近70%,天然气对外依存度超过40%,超过美国成为世界第一大石油进口国。随着'一带一路'倡议推进,我国石油企业要实现与富油国经贸合作,势必与跨国石油公司展开竞争,没有强大的技术实力是难以取胜的。

Taking the three major oil companies in China as the research object, the BP neural network model is used to select the index system from the perspective of input and output. The expert opinion method and the analytic hierarchy process are used to determine the indicators and their weights, and the technical innovations of the three major oil companies are evaluated. Efficiency. The research shows that the technological innovation efficiency of China’s three major oil companies is at a moderately high level and is on the rise, and there is still room for improvement.
