Este trabalho de investigação pretende ser um contributo para o debate sobre a concen-tração do mercado de auditoria, num setor caracterizado pela exigência da qualidade e independência do auditor, bem como na sua importância para a credibilização da infor-mação financeira divulgada. A temática da concentração do mercado de auditoria tem-se tornado tema de debate, impulsionado sobretudo pela perceção da crescente posição de domínio de um reduzido número de firmas. Além disso, a crise internacional de 2008 trouxe à luz um conjunto de práticas éticas e de gestão algo duvidosas, que não foram identificadas pelos auditores.
Estes fenómenos colocaram, aos países, uma maior urgência na necessidade de refor-mular os mecanismos de governação das sociedades e reformar e aperfeiçoar os mode-los de supervisão, tendo a União Europeia em 2014 emitido legislação nesse sentido. Nesta dissertação, num primeiro momento, é feita a revisão da literatura, onde se apre-sentará uma compilação de diversos estudos sobre a concentração do mercado de audi-toria, tanto a nível internacional como em Portugal, para além de abordar os pontos (a) benefícios e malefícios derivados da concentração, (b) fatores que contribuíram para a concentração e (c) propostas legislativas dirigidas a este fenómeno. Posteriormente, procede-se à explicação da metodologia utilizada e à apresentação do caso empírico, o qual visa aferir o grau de concentração do mercado de auditoria para as empresas cotadas no mercado português regulamentado. Os resultados obtidos confir-mam a existência de uma elevada consolidação de mercado em 2014, tendência que se tem vindo a incrementar desde 2004.
This study intends to contribute for the debate regarding the audit market concentration, in an industry characterized by requirement for quality and auditor independence, as well as its importance to enhance the credibility of the published financial information. The subject of the audit market concentration has become a matter of debate driven, mainly, by the perception of the growing position of dominance of a few firms. In addition, the international crisis of 2008 brought to light a set of unethical practices and misman-agement that the auditors did not identify. These phenomena have placed a greater sense of urgency for the countries to reform the corporate governance mechanisms and improve the current supervision models, having the European Union issued, in 2014, legislation regarding this matter. Initially, in this study, we performed the literature review, in which we will present a com-pilation of various studies on the audit market concentration, internationally and in Portu-gal, in addition to addressing the points (a) derived benefits and harms from the concen-tration, (b) factors contributing towards the consolidation and (c) legislative proposals ad-dressed to this subject. Later, we proceeded to the explanation of the used methodology and presented the em-pirical case, which aims to assess the degree of audit market concentration for listed companies in the Portuguese stock market. The results confirm the existence of a high market consolidation in 2014, a trend that has been increasing since 2004.
