The research used Real Options Theory and Growth Options Theory to frame how firms may respond to uncertainty. These theories offer contrasting interpretations: Real Options Theory treats uncertainty primarily as a challenge, whereas Growth Options Theory treats it as an opportunity. The authors concluded that the reported results were more consistent with the latter perspective in the context of green M&A.

The study’s mechanism analysis identified two associations that could help explain the findings. Higher climate policy uncertainty was associated with heightened environmental regulatory intensity and enhanced internal green governance. The abstract reports these as evidence consistent with the proposed channels, rather than establishing that the mechanisms caused the increase in green acquisitions.

Green M&A undertaken under higher climate policy uncertainty was also associated with stronger subsequent green innovation outcomes. However, the researchers did not find corresponding evidence for financial performance. The available evidence is an abstract of an empirical study focused on Chinese listed firms over the stated period; it does not provide enough methodological or robustness detail to assess how broadly the results may apply. The article was published as an accepted version subject to further edits.
