Study On The Core Competitiveness Of Chinese Oil Companies Overseas Merger And Acquisition Evaluation

International overseas mergers set off again and again, overseas mergers and acquisitionsas the world’s largest oil companies to raise their competitiveness and one of the importantmeans of optimizing the allocation of resources at the global level, has become the focus ofresearch in the field of economics. In recent years, represented by PetroChina, Sinopec,CNOOC, Chinese oil companies are also actively go out and implementation of overseasmergers and acquisitions, to lessen China’s oil production cannot meet the demand gap, our oilcompanies increased the number of overseas mergers and acquisitions, overseas mergers andacquisitions amounts are all being refreshed.Oil companies ’ overseas mergers and acquisitions in the country when in full swing, weshould also see the enormous risks of overseas mergers and acquisitions, rising amount ofmergers and acquisitions is proportional to the effect of mergers and acquisitions, overseasmergers and acquisitions is to enhance the core competitiveness of the company, the companyto gain a competitive advantage, are worthy of our study. Therefore, this article will use threemethod--empirical study of Entropy-right method, Factor Analysis method and TOPSISmethod on core competitiveness of the three major oil companies before and after the mergerhad been raised and the mergers and acquisitions year effectiveness study, to explore the threemajor oil companies in recent years improvement of core competitive power of overseasmergers and acquisitions.Draw basic conclusions in this article are as follows：First of all, using TOPSIS methodconducted research on the effect of three large petroleum companies merger and acquisition ofthe year, PetroChina found maximally enhance the core competitiveness is in2005, effect theworst of2009year; Sinopec overseas mergers and acquisitions to enhance the core competitive power is the biggest in2009, smallest is2010;CNOOC’s overseas acquisitionsmaximally enhance the core competitiveness of is2010, the smallest is2002. Petroleum inrecent years of volatile and declining overseas merger and acquisition effects,CNOOC mergerand acquisition effect has improved,Sinopec’s less volatile, the trend is notobvious.Secondly,in entropy-right method to three large oil companies after the evaluation ofthe core competitive power of overseas mergers and acquisitions, discover petroleum mergersand acquisitions work best, mergers and acquisitions that enhance the core competitiveness ofoverseas mergers and acquisitions accounting for83.3%of the total, followed by CNOOC,Sinopec’s worst. Finally, in three major oil companies by means of factor analysis after theevaluation of the core competitive power of overseas mergers and acquisitions, concluded thatmergers and acquisitions in the oil works best, improve the core competence of the share ofoverseas mergers and acquisitions reached100%, followed by Sinopec, CNOOC is the worst.
