1. Relations bilatérales entre aéroports secondaires et compagnies à bas coût: Quelles justifications concurrentielles sur la base des gains d’efficacité ?

A significant share of airline activities is characterized by bilateral relationships due to various market imperfections. Two important features of such bilateral relationships are bargaining power available to the contracting parties and the resulting trend to vertical integration. To highlight the corresponding effects and an “efficiency-based defense” approach, we develop a simple model including progressive congestion costs and economies of scale due to the presence of fixed costs. In this framework, we examine the output corresponding to airport power and the output corresponding to airline power. We then compare these results with output corresponding to integrated activity. We check whether some potential productive efficiency gains, well documented in literature, are not offset by allocative inefficiency and subsequent price increase. Our contribution seems to legitimate some flexibility concerning the competition assessment of vertical integration in such a market setting.

2. Modèle de pilotage de la performance globale basé sur les perceptions des parties prenantes portuaires

Our paper presents an integrated performance monitoring model based on port stakeholders’ perceptions. This work aims to contribute to the theoretical reflection on the integration of the stakeholder theory to the global performance monitoring in the organizations. From a literature review on the stakeholder theory and the global performance concept, we have focused on research papers presenting the blending of these two areas. Then, we have selected theoretical frameworks in order to develop a disaggregated model from multidimensional perspective. Our model includes different steps ranging from the port stakeholders’ analysis using the Generalized Procrustes Analysis, to a balanced scorecard’s development based on port stakeholders’ expectations using the Principal Components Analysis. We have applied this model to Radès port currently characterized by various unidimensional performance models and sovereign port authority. The suggested balanced scorecard could serve as a decision-making tool and global performance monitoring model reinforced by port stakeholders’ cohesion.

3. Positionnement stratégique de la Chine en Méditerranée : le projet “Belt and Road Initiative”

The Belt and Road Initiative (BRI) project identify the Mediterranean as a strategic area for new maritime networks in the 21st century. This paper highlights current maritime strategies in the Mediterranean as well as their impact on the spatial configuration of logistics networks on the Asia-Europe maritime route. The results suggest that the position of China in the Mediterranean is reinforced because Beijing coordinates several operations in ports infrastructure. Our analysis shows that the flow of containers in a sample of ports located on the Asia-Europe maritime route is increasing as well as the Logistics Shipping Connectivity. To explore this issue, we focus on the port of Pierus considering the Chinese investments since 2008. The results suggest that ports connectivity is increasingly significant in the port located nearby the maritime route with an interest for Beijing.

4. Méthodologie de filtrage et de traitement de données de signalisation de la téléphonie mobile pour la construction de matrice origine-destination: Application à la Région Rhône-Alpes

Origin-Destination (O-D) matrices are a necessary input for transport planning to support both mobility modeling and analysis tasks. Several research works have investigated the possibility to compute O-D matrices from mobile phone data. However, most of these works rely on billing data (call detail records). In this paper, network signaling data is leveraged, and the advantages of this kind of data to produce O-D matrices are highlighted. A three-step algorithm based on data filtering, users’ home detection and sector-based expansion factors is proposed. Additionally, a validation step is included in order to compare the resulting O-D matrices with external sources of data. To that end, the latest travel survey data available for the Rhône-Alpes region (EDR) is exploited. The proposed approach for O-D construction generates a matrix structure and a number of trips that are close to the travel survey data. The regression analysis of the number of trips from mobile phone data with respect to the number of trips from EDR provides a coefficient of determination of 0.95, close to 1, and a small intercept value. In the last part of the paper, the limits of this work are addressed and discussed. And, future directions for improvement and extension are proposed.
