Ce travail doctoral se situe dans le cadre du management public qui s'intéresse principalement à étudier l’impact des modes de gouvernance public-privé sur l’efficience technique des remontées mécaniques. Une étude empirique a été menée auprès de 68 entreprises de remontées mécaniques sur cinq ans (2006-2010). Ces données ont été traitées au moyen d’une étude quantitative confirmatoire à l’aide d’un modèle statistique. La recherche quantitative a pour objectif final de tester la validité des deux modèles de recherche proposée à l’issue de l’analyse de la littérature. Le premier modèle de frontière stochastique se compose de trois variables explicatives (productivité du capital, productivité du travail et moment de puissance), et de trois variables de contrôle (taille, altitude et effectif) et d'une variable à expliquer (la journée skieur). Le second se compose de deux variables explicatives (régie et SEM) et d’une variable à expliquée (l’inefficience technique). Les résultats de cette recherche mettent en avant l'importance des modes de gouvernance (régie ou SEM) dans le processus d’augmentation de l’efficience technique des remontées mécaniques. Une deuxième étude empirique (2011-2013) approche la compétitivité par la mesure de la productivité des opérateurs de remontées mécaniques. A l’aide de l’indice de productivité de Malmquist et ses deux composantes, nous cherchons à appréhender les changements de productivité entre deux périodes de temps, puis, dans un second temps, cette productivité est décomposée en deux éléments afin de mettre en évidence le progrès technologique. Alors,la relation entre taille et variation de l’efficience technique est vérifiée. / Public-Private Partnership is a tool for modernization and renewal of public intervention, its main goal is to achieve very high levels of performance. This doctoral work is therefore in the context of public management that focuses on studying the impact of public-private modes of governance on the technical efficiency of ski lifts. To answer our questions, an empirical study was conducted among 68 ski lift companies over five years (2006-2010). These data have been processed using a quantitative confirmatory study using a statistical model. To test the validity of the two models proposed by the literature, a quantitative research has been conducted. The first stochastic frontier model consists of three variables (capital productivity, labor productivity and power momentum), and three control variables (size, altitude and staff) and a dependent variable (the skier day). The second model of technical inefficiency consists of two explanatory variables (“time and materials » and SEM) and an explanatory variable (technical inefficiency). The results of this research outline, among other things, the importance of modes of governance (“time and materials » or SEM) in the process of increasing the technical efficiency of ski lifts. The second empirical study (2011-2013) which approaches the competitiveness of the French winter sports resorts by the measure of the productivity of the operators of ski lifts. By means of the indication of productivity of Malmquist and its two constituents, we look to arrest the changes of productivity then, this productivity is decomposed into two elements. Then, the relation between size and variation Technical efficiency is verified.

<p>Cilj ovog istraživanja bio je da se razvije model za ocjenu<br />efikasnosti i efektivnosti željezničkih operatera koji bi<br />bio u funkciji povećanja konkurentskih sposobnosti istih. Da<br />bi se to ostvarilo na osnovu stanja u literaturi i praksi,<br />definisani su i vrednovani kriterijumi koji utiču na<br />efikasnost i efektivnost i izvršen njihov izbor primjenom<br />fazi AXP. Razvijeni su modeli za ocjenu efikasnosti<br />željezničkog operatera. U razvoju modela korišćeni su<br />principi DEA i fazi logike da se modeluje neodređenost u<br />podacima i koristi ekspertsko znanje za ocjenu. Testiranjem<br />modela na željezničkom operateru u BiH zaključeno je da je<br />model primjenljiv kao alat za ocjenu efikasnosti.</p> / <p>The objective of this study was to develop a model for evaluating the<br />effectiveness and efficiency of railway undertakings, which would be<br />aimed at increasing the competitive capabilities of the railway<br />undertakings. In order to achieve this on the basis of the state in<br />literature and practice, the criteria that affect the efficiency and<br />effectiveness are defined and evaluated and their selection is made<br />with the application of Fuzzy AHP. Models for the assessment of the<br />efficiency of railway undertakings have been developed. In developing<br />the model, the principles of DEA and Fuzzy logic have been used to<br />model the uncertainty in the data and to use the expertise for<br />assessment. By testing the model on the railway undertaking in Bosnia<br />and Herzegovina it was concluded that the model is useful as a tool for<br />the assessment of efficiency.</p>
