Is lithium affecting the US oil and gas industry strategies? Lithium has an increasingly strategic role as clean technologies emerge, affecting the strategies of oil and gas companies in response to energy trends. This paper contributes to this literature, studying the dynamics of lithium industry and mergers and acquisitions in the US oil and gas industry in time–frequency domain. Methodologies based on continuous wavelet transform and vector autoregression models are used, and the results indicate that both time series are correlated in the long term, where mergers and acquisitions’ US oil and gas industry dependence on lithium industry has increased, starting in the early 2014 until the end of the sample. Evidence of causality is not found between both time series.

锂会影响美国的石油和天然气行业战略吗？随着清洁技术的出现，锂在战略方面的作用越来越大，影响了石油和天然气公司响应能源趋势的战略。本文为该文献做出了贡献，在时频范围内研究了锂行业的动态以及美国油气行业的并购。使用基于连续小波变换和向量自回归模型的方法，结果表明这两个时间序列长期相关，从2014年初开始，并购对美国石油和天然气行业对锂行业的依赖性增加直到样本结束。在两个时间序列之间都找不到因果关系的证据。
