S’appuyant sur les théories du financement hiérarchique et du compromis, cette recherche se donne pour objectif de tester empiriquement la relation structure financière-institution. Ces deux notions partagent des caractéristiques communes favorisant leur association conceptuelle à travers le ratio d’endettement cible spécifiquement via le comportement de conservatisme financier des entreprises. Cela ouvre de nouvelles possibilités d’analyses de ladite relation, notamment, en mobilisant le néo-institutionnalisme. Un échantillon de 204 entreprises françaises cotées à la bourse de Paris, ayant des données complètes entre 1999 et 2007, a servi à entreprendre le volet empirique de l’étude. Les principaux résultats indiquent que l’ensemble des déterminants traditionnels de la structure financière, à l’exception de la taille, joue un rôle important dans la politique de financement de ces entreprises. Le niveau de corruption et la liquidité du marché boursier français (variables institutionnelles juridico-financières) n’influencent pas le choix du niveau d’endettement, mais jouent plutôt un rôle significatif dans le choix de la maturité de la dette. Par ailleurs, la structure financière de ces entreprises converge lentement mais sûrement vers son niveau cible. / Based on the pecking order and trade-off theories, this research aims to test empirically the relationship between corporate capital structure and institution. Both concepts share common characteristics fostering their conceptual association through the target debt ratio specifically via corporate behavior of financial conservatism. This opens new possibilities for analysis of that relationship, in particular, by mobilizing the new institutionalism framework. A sample of 204 French companies listed on the Paris stock exchange, with complete data between 1999 and 2007, was used to undertake the empirical part of the study. The main results indicate that all the traditional determinants of capital structure, except the size, play an important role in the financing policy of these companies. The level of corruption and the French stock market liquidity (legal and financial institutional variables) do not influence the choice of debt level, but rather play a significant role in the choice of debt maturity. In addition, the financial structure of these companies converges slowly but surely toward its target level.

Le financement à court terme est le parent pauvre de la théorie financière. Pourtant, les moyennes entreprises françaises utilisent fortement ce financement. Ce travail a pour objectif d’analyser les déterminants du financement à court terme pour ces entreprises. La première partie vise à établir une revue de littérature des théories permettant d’expliquer l’utilisation du financement à court terme. La deuxième partie vient tester empiriquement ces théories sur deux échantillons, à savoir 201 entreprises familiales et 1 453 entreprises managériales. Il s’agit, d’une part, de caractériser les moyennes entreprises non cotées et d’autres part, de mettre en évidence les déterminants à l’utilisation de financement à court terme. Les principaux résultats indiquent que le financement à court terme est un outil de gestion au service de la moyenne entreprise. Il peut aussi assumer deux rôles, un compensatoire et/ou un de trésorerie passive. Par ailleurs, on met en évidence que les entreprises managériales et familiales exploitent différemment le financement à court terme. / Short-term financing is forgotten by theory of corporate finance. However, French medium-sized firms use a lot this source of funding. The objective of this thesis is to analyze the determinants of short-term financing for these firms. The first part aims to establish a literature review of theories to explain the use of short-term financing. The second part empirically checks these theories on two samples, specifically 201 family businesses and 1,453 managerial firms. On the one hand, it is a question of characterizing the unlisted medium-sized enterprises and on the other hand, highlighting the determinants of the use of short-term financing. The primary results indicate that short-term financing is a management tool for the medium-sized enterprise. It can also have two functions, one compensatory and / or one passive cash. Furthermore, it brings out that managerial and family businesses exploit short-term financing differently.

Syftet med denna studie är att undersöka och analysera det statistiska signifikanta sambandet mellan kapitalstruktur och lönsamhet för bolag noterade på OMXS Large Cap. Det görs under tidsperioden före samt under Covid-19 och studien använder sig av ett antal variabler för att kunna analysera ett potentiellt samband över en femårsperiod. Uppsatsen undersöker även om det eventuella sambandet ändras av Covid-19 pandemin. Studien har utgått ifrån en kvantitativ metod med en deduktiv ansats. För att ge svar på forskningsfrågan har paneldata regressioner genomförts på 30 bolag noterade på OMXS Large Cap för perioderna 2017-2019 och 2020-2021. Studien kommer fram till att det finns statistiskt signifikanta samband mellan kapitalstruktur och lönsamhet avseende vissa variabler samtidigt som studien finner att det inte finns samband för vissa andra variabler. Resultaten visar på både negativa och neutrala samband och slutsatsen att hög skuldsättningsgrad har en negativ effekt på lönsamhet dras, vilket stämmer överens med tidigare forskning inom ämnet. Sambanden som hittades visade sig ändras mellan perioden innan och under Covid-19 / The purpose of this study is to investigate the statistically significant relationship between capital structure and profitability for companies listed on OMXS Large Cap. This is done in connection with Covid-19 and the study uses a number of variables to analyze a potential relationship over a five-year period. The study  further examines if the possible relationship is affected by Covid-19. The study has been based on a quantitative method with a deductive approach. In order to answer the purpose of the study, the authors have carried out panel data regressions on 30 companies listed on OMXS Large Cap for the periods 2017-2019 and 2020-2021. The study finds that there exists statistically significant relationships between capital structure and profitability for some of the variables, whilst other variables show no significance. The results show both negative and neutral relations and the conclusion that a higher debt ratio has a negative effect on profitability is drawn, showing the same result as previous research. The results also show that the relationships differ from before the pandemic period to under.

Syftet med denna studie är att analysera eventuella kapitalstruktursförändringar i samband med Covid-19 pandemin hos svenska företag noterade på Stockholmsbörsen, OMXS, inom Large Cap. Urvalet utgörs av företag inom alla sektorer i Large Cap, exklusive finanssektorn. Sambandet mellan bolagens beroende och oberoende variabler analyseras före och under pandemins tidsperiod, 2015–2022. De beroende variablerna utgörs som Proxy för kapitalstruktur och omfattas av totala-, kortfristiga-, och långfristiga skulder i förhållande till totala tillgångar. Medan de oberoende variablerna utgörs av företagsstorlek, lönsamhet samt tillväxt. För att uppnå detta baseras uppsatsens teoretiska ramverk på Modigliani och Miller proposition 1 & 2, Pecking Order teorin och Trade Off teorin tillsammans med tidigare empiriska studier samt undersökningar. Uppsatsens analyser omfattas av en deskriptiv analys av samtliga variabler, en korrelationsanalys av de oberoende variablerna och slutligen flera multivariata regressionsanalyser mellan samtliga variabler. För att erhålla de mest valida och reliabla slutsatserna kommer uppsatsen tillämpa en kvantitativ forskningsmetod och en deduktiv ansats. Uppsatsens resultat fann flest statistiskt signifikanta samband mellan samtliga skuldkvoter och företagsstorlek. Uppsatsens slutsats konstaterade att kapitalstrukturen hos OMXS företag inom Large Cap hade förändrats under pandemin i jämförelse med före pandemin. Sammantaget bidrar denna uppsats till en djupare förståelse för sambandet mellan samtliga analyserade variabler baserat på en historisk bakgrund. Därmed kan svenska bolag inom alla sektorer, exklusive finanssektorn, skapa en bättre uppfattning kring sina kapitalstrukturer inför framtida finanskriser. / The purpose of this study is to analyze potential capital structure changes in connection with the Covid-19 pandemic among Swedish publicly traded companies on the Stockholm Stock Exchange, OMXS, within Large Cap. The sample consists of companies across all sectors within Large Cap, excluding the finance sector. Focusing on the relationship between the dependent and independent variables before and during the period of the pandemic, 2015–2022. The dependent variables consist of total-, short- term-, and long- term debt as a proportion to the total assets. These dependent variables constitute as a Proxy for capital structure. The independent variables include size, profitability and growth. To accomplish this, the theoretical framework for this essay is based on Modigliani and Miller proposition 1 & 2, The Pecking Order Theory, The Trade Off Theory along with previous empirical studies. The analyzes contains of a descriptive analysis of all variables, a correlation analysis of the independent variables, and lastly several multivariate regressions analyses between all variables. In order to make it possible to acquire the most valid and reliable conclusions, the study will be based on a quantitative method, applying a deductive approach. The results found the most statistically significant relationships between all debt ratios and company size. The conclusion stated that the capital structure of OMXS companies, within Large Cap, had changed during the pandemic compared to before. In summary the results contribute to a deeper understanding of the relationship between all analyzed variables based on a historical background. Hence Swedish companies within these sectors can gain a better understanding of their capital structure for future financial crises.
