| The true purpose of enterprise mergers and acquisitions is to achieve synergies and improve the competitiveness of enterprises.A successful merger and acquisition activity is formed by the synergistic effects of multiple mergers and acquisitions.However,not all M&A activities can generate synergies,so it is particularly important for enterprises to study synergies before M&A,which is conducive to correctly evaluating M&A activities and evaluating M&A risks.Firstly,this article provides a specific conceptual definition of mergers and acquisitions and synergistic effects,and analyzes theories from literature to derive the main effects of mergers and acquisitions.Taking the acquisition of Carrefour China by Suning.com in 2019 as the research object,this paper uses literature review,financial index analysis and other methods to analyze the background,motivation,process and synergy of M&A,so as to evaluate the results of M&A.This paper analyzes the cooperation relationship between Suning.com and Carrefour China from the financial and non-financial aspects,and analyzes the synergy of mergers and acquisitions after the merger.Conduct research on the effects of synergies and summarize the results of mergers and acquisitions synergies.It is found that after the completion of M&A,the synergistic effect only affects some indicators of the enterprise and the impact time is short,and the effect on the operation,management and finance of the enterprise is not prominent or even negative.The synergy of M&A can’t fully achieve the real purpose of M&A,and the business risk will weaken the future development ability of enterprises.In this paper,the author puts forward relevant countermeasures against the situation that affects the synergy effect in case analysis,evaluates the long-term and far-reaching significance of the synergy effect of mergers and acquisitions,draws more reasonable conclusions,and further improves the analysis method and framework design,hoping that the synergy effect of mergers and acquisitions can create value for enterprises and enhance their competitiveness for a long time. |
