This book summarizes the findings of research studies concerning the impact and consequences and constraints of the IFRS implementation within the context of the Czech Republic economy and Czech accounting and social-economic space as in one of the emerging markets. The research projects were performed at the University of Finance and Administration in the years of 2012-2017. Within these projects, a number of articles and research studies which analyze and characterize the conditions and problems as well as the process and level of IFRS implementation in the Czech Republic have been carried out and published (the coauthors are presented in the book). The aim of this publication is to present and summarize the main findings achieved in these projects to provide a more comprehensive overview of the examined issue and to allow a new more comprehensive view on the subject.
