With the increasingly severe global environmental problems, green development has become an important path. It can promote the transformation and upgrading of enterprises and the sustainable development of the economy and society. The concepts of green economy and circular economy have gradually taken root in people's hearts, which will minimize the impact on the environment. Meanwhile, it also achieves a win-win situation for both the economy and the environment. As one of the important means to realize green development, corporate green M&A has received extensive attention from academia and the industry in recent years. The purpose of this paper is to explore the impact of corporate green M&A on corporate performance, including the effect of green M&A on corporate performance, the motivation of corporate green M&A and the realization of the path of these three aspects. This paper serves as a valuable reference for other enterprises seeking to engage in environmentally friendly mergers and acquisitions, facilitating performance improvement and bolstering market competitiveness.
