Dans un contexte d’harmonisation comptable internationale visant à améliorer la qualité de l’information financière publiée par les groupes internationaux afin d’en assurer l’utilité, notre recherche doctorale a pour objet d’apporter une contribution à l’évaluation de l’utilité et de la comparabilité de l’information sectorielle. Cette recherche adopte une approche qualitative mono-sectorielle à travers l’étude du contenu des rapports de recommandation des analystes et des rapports annuels des grands groupes hôteliers internationaux, et une approche internationale à travers la comparaison des référentiels IAS/IFRS et US GAAP. Nous proposons en premier lieu d’étudier l’utilité de l’information sectorielle pour les analystes financiers à travers l’utilisation qu’ils en font dans leurs rapports et le lien de cette utilisation avec l’exactitude des prévisions qu’ils réalisent. Nous analysons ensuite l’évolution de la comparabilité de l’information sectorielle « normée » publiée par les groupes et la comparabilité de leurs pratiques de publication hors annexe. En raison de la diversité des pratiques de publication des firmes, l’utilité et la comparabilité de l’information sectorielle publiée par les groupes hôteliers internationaux demeurent perfectibles. / International accounting harmonization aims to improve financial reporting quality in order to enhance its usefulness. In this context, we study the usefulness and the comparability of segment information. Our research is mainly qualitative – analysis of annual reports and analysts’ reports contents - , hotel industry based and IAS/IFRS versus US GAAP focused. First, we address whether segment information is useful for financial analysts assessing usefulness through its use and its link with forecasts’ precision. Second, the research deals with the evolution of normalized segment information comparability and with the comparability of segment voluntary disclosures reported by international hotel groups. We find that, mainly because of the heterogeneity of disclosure practices, both usefulness and comparability of segment information remains incomplete and perfectible in the international hotel industry.

Nos travaux, dans le prolongement de recherches envisageant l’harmonisation comptable internationale (IAS/IFRS) et la mise en place des indicateurs de Responsabilité Sociale de l’Entreprise (RSE) sous un angle processuel et « historico évolutif », tendent à s’en démarquer en recherchant les moyens d’analyser l’information issue du reporting financier (IAS/IFRS) et extra-financier (RSE) dispensée durant la période 2006-2010 par les sociétés cotées composant les indices boursiers français du CAC 40 et du SBF 120, d’une part, et allemands du DAX 30 et du DAX 100, d’autre part, et en substituant à une approche souvent inductive dans ce domaine une démarche hypothético-déductive. Ils mettent en regard, d’une part, les données recueillies et, d’autre part, les intérêts des actionnaires/investisseurs ainsi que de l’ensemble des parties prenantes de part et d’autre du Rhin, sur le fondement théorique de la théorie de l’agence et la théorie des parties prenantes. La méthode employée, à la fois quantitative et qualitative, vise d’abord à utiliser des outils de mesure se fondant sur des moyennes, médianes et analyses de régression combinant plusieurs variables exprimées pour l’essentiel sous la forme de ratios comptables et financiers (IAS/IFRS) ; cette mesure s’étend à un recensement de l’occurrence de mots dans les supports d’information extra-financière (rapports RSE et de développement durable). Puis à interroger les responsables administratifs et financiers en charge de l’application du référentiel IAS/IFRS ainsi que les responsables de la communication RSE et du développement durable des sociétés de notre panel, au moyen de questionnaires se fondant sur les outils de « logique floue ». Nous ne cherchons pas à mesurer l’incidence des normes IAS/IFRS et des indicateurs RSE ni sur la performance financière, ni en taux de retour sur la valeur boursière. Nous observons par nos résultats des nuances de perception des normes IAS/IFRS et des objectifs de RSE dans le reporting financier et extra-financier susceptibles d’être imputées à des facteurs socioculturels, et répondant à une gouvernance plus actionnariale en France qu’en Allemagne. / This study, in the extension of researches aimed at harmonising accounting internationally (IAS/IFRS) and implementing Corporate Social Responsibility (CSR) indicators from a processual and “historical evolutional” angle, tends to differ from them by focusing on the means to analyse the information issued from financial (IAS/IFRS) and extra-financial (CSR) reporting released during the 2006-2010 period by the listed companies which compose the French and German stock market indexes respectively CAC40/SBF120 and DAX30/DAX100, and replacing an oftentimes inductive approach in this field with a hypothetical and deductive process. It compares the collected data on the one hand, and the needs of shareholders/investors and third parties as a whole on the other hand, on either side of the Rhine, on the basis of the theoretical frame of the agency theory and the stakeholder theory.The method employed, which is both quantitative and qualitative, aims to do as follows. First use of tools for measuring based on averages, medians and regression studies combining many variables essentially expressed in the form of accounting and financial ratios (IAS/IFRS); this measure extends to the listing of words occurrence in the extra-financial information supports (CSR and sustainability reports). Then question the administrative and financial managers in charge of the application of the IAS/IFRS referential and the managers responsible for the CSR and sustainability communication within these companies we selected with reference to matrixes based on the “fuzzy logic” theory tools. We do not investigate the influence of IAS/IFRS standards/CSR indicators neither on financial performance nor in terms of expected return on the capital asset. We can observe that our results show nuances of perception of IAS/IFRS standards and CSR goals in the financial and extra-financial reporting that are likely to be attributed to socio-cultural factors, and reflecting a governance much more aimed at shareholders in France than in Germany.

There is a significant number of differences between the Czech accounting legislation and the International Financial Reporting standards in the area of posting and presentation of non-current assets.
