L’objet de cette thèse est d’expliquer le lien entre utilisation de marques et activités innovantes. Le premier chapitre décrit les principaux aspects juridiques des marques et passe en revue la littérature en économie et gestion s’y rapportant. Le second chapitre analyse comment et pourquoi les firmes utilisent les marques et comment celles-ci s’intègrent dans leurs activités innovantes. À travers une approche théorique et empirique, nous montrons que les marques sont utilisées en lien avec les innovations prenant place à l’interface du marché, principalement les innovations de produit et de marketing. Le troisième chapitre étudie les interactions entre marques et brevets dans la protection de l’innovation. Nous montrons que selon les caractéristiques du marché ils peuvent se complémenter ou se substituer l’un à l’autre. Dans le dernier chapitre, nous explorons les schémas d’utilisation de marques par les universités et leur lien avec les activités de recherche de ces institutions. / This thesis aims at explaining the link between trade mark use and innovative activities. The first chapter describes the main legal aspects of trade marks and reviews existing literature in economics and management relating to them. The second chapter analyses how and why firms use trade marks and how they integrate them in their innovative activities. Through a theoretical and empirical approach, we show that trade marks are used in relation to innovations which are at the interface of the market, mainly product and marketing innovations. The third chapter then studies the interrelated effect of trade marks and patents in the protection of innovation. We show that depending on market characteristics, they may complement or substitute each other. In the fourth and final chapter, we explore the patterns of trade mark use by academic institutions, and investigate how these relate to their research activities.

Questa tesi analizza le determinanti e gli effetti dell'innovazione attraverso un'analisi empirica. Nel primo capitolo viene analizzato l'impatto delle leggi di proprietà intellettuale sull'innovazione domestica in campo farmaceutico. Nel secondo capitolo, in cui vengono usati dati a livello di impresa, si studia la correlazione tra innovazione, export, produttività e vincoli finanziari. Infine nell'ultimo capitolo si studia l'effetto dell'innovazione domestica nell'attrarre investimenti diretti esteri. Mentre nel primo e nell'ultimo capitolo l'innovazione viene misurata come output, usando il numero di brevetti attribuiti ad un determinato paese, nel secondo capitolo vengono usati dati di R&D, e quindi di input di innovazione. / This dissertation analyses the determinants and the effects of innovation using an empirical analysis. In the first chapter the impact of Intellectual Property Rights on domestic innovation in the pharmaceutical sector is estimated. In the second chapter the correlation between innovation, export, productivity and financial constraint is studied at the firm level. Finally, in the last chapter the role of domestic innovation in attracting Foreign Direct Investments is estimated. While in the first and in the last chapter innovation output is considered, and innovation is proxied by patent data, in the second chapter innovation input is taken into account, and R&D data are used.
