[en] The research activity is one of the fundamental missions of university. This mission is in charge of the work linked to academic structures of research. For effective university management it is important to have methodologies that allow the analysis of those factors that influence the performance level of these structures, in order to generate strategies and policies into university which increase the effects on the results of the academic research, according to the institutional mission and needs from the environment of influence. In essence, there are three motive issues for this study. First, the fact that collaborative research is nowadays the most significant activity in the global scientific community. Second, the general consensus about the critical value to the science and technological policy, the evaluation and assessment of the scientific, economical and social impact of the research and development activities (R&D). And third, the limited evidence of studies in the scientific literature focused on both topics at microlevel in the academic context. Referring to previous issues, the objective of this Thesis is to analyse the dynamics, effects and potentials based on the performance of the academic research units and their link in R&D collaborative activities. For that, in the first part of the Thesis, the problem and objectives of the research are defined, the state of art in the study topic is reviewed, and finally, the hypothesis are formulated from the proposed research model. Through the case study methodology of 198 research groups (GI) of the Technical University of Valencia (UPV), mainly link to Basic and Technical Sciences, the second part of the Thesis presents the methodology and results of the valuation of the research model. Basing on positive philosophy with deductive focus and deterministic method, in this study that can be defined as confirmatory two facts in particular are contrasted and proved. First one, the pertinence of the research assessment of GI under a multicriterion focus, which goes further than traditional productivity measurement and can be complemented with other criteria like efficiency, quality and impact. Second one, the value of the collaborative activities to improve the performance level of the GI, especially when it is linked to reach improvement in the scientific quality and impact of the academic research results.

[es] La labor de investigación se considera una de las misiones fundamentales de la universidad. En la medida que el cumplimiento de esta misión se encuentra a cargo del trabajo asociado a las estructuras académicas de investigación, resulta de vital importancia para una gestión universitaria efectiva, el análisis de aquellos factores que influencian el nivel de rendimiento de estas estructuras, con el fin de generar estrategias y políticas que potencien el alcance de los resultados de la investigación académica, en función de la misión institucional y las necesidades de su entorno de influencia. Esencialmente, tres hechos motivan esta investigación. El primero, referido al hecho de que la investigación colaborativa es ahora la forma más significativa de actividad en la comunidad científica global. El segundo, relacionado con el reconocimiento del valor crítico que tiene sobre la política de ciencia y tecnología, la evaluación y la garantía del valor e impacto científico, económico y social, de las labores de investigación y desarrollo (I+D). El tercero, la escasez de literatura científica que aborde estos temas a micronivel dentro del ámbito universitario. Por lo anterior, el objetivo de esta Tesis es analizar las dinámicas, efectos y potencialidades que tienen sobre el rendimiento de las unidades académicas de investigación, la vinculación de éstas en actividades de colaboración en I+D. Para ello, en la primera parte se presenta el problema de investigación, se definen los objetivos de la investigación, se reconoce del estado del arte en el tema de estudio y se establecen las hipótesis que se derivan del modelo de investigación propuesto.
