Estimation des effets de proximité dans le processus de convergence régionale : une approche par l'économétrie spatiale sur 92 régions européennes (1…
2002
L'objectif de cet article est d'examiner les conséquences de la dépendance spatiale sur la croissance régionale et le processus de convergence. Sur un échantillon de 92 régions européennes sur la période 1980-1995, nous montrons que le modèle de b-convergence absolue doit être re-spécifié en raison de la présence d'auto-corrélation spatiale. Les méthodes de l'économétrie spatiale nous orientent vers une spécification avec erreurs spatialement auto-corrélées qui nous permet de mettre en évidence un effet de débordement géographique. Nous montrons ainsi que le taux de croissance d'une région est influencé positivement par les taux de croissance des régions contiguës.

Une analyse exploratoire des disparités régionales dans l'Europe élargie
2005
http://www.regionetdeveloppement.u-3mrs.fr/; National audience; L'objectif de cet article est d'analyser les inégalités régionales dans l'Union Européenne élargie à l'aide de l'Analyse Exploratoire des Données Spatiales appliquée aux PIB par tête des 258 régions de l'Europe des 27 sur la période 1995-2000. Les résultats montrent l'existence d'une forte autocorrélation spatiale globale et locale ainsi qu'une forte hétérogénéité dans la distribution des richesses. Ils montrent également un changement de polarisation, puisque l'élargissement conduit à un schéma de polarisation Nord-Ouest - Est à la place du schéma Nord-Sud traditionnellement mis en évidence dans la littérature. Finalement, cet…
Inverse problems for a fractional conductivity equation
2020
This paper shows global uniqueness in two inverse problems for a fractional conductivity equation: an unknown conductivity in a bounded domain is uniquely determined by measurements of solutions taken in arbitrary open, possibly disjoint subsets of the exterior. Both the cases of infinitely many measurements and a single measurement are addressed. The results are based on a reduction from the fractional conductivity equation to the fractional Schr\"odinger equation, and as such represent extensions of previous works. Moreover, a simple application is shown in which the fractional conductivity equation is put into relation with a long jump random walk with weights.
Growth and convergence in Africa: The impact of spatial effects
2010
The aim of this paper is to study the impact of spatial effects on convergence process in Africa over the period 1975-2000. Taking into account these effects through the methodology of Exploratory Spatial Data Analysis (ESDA) and spatial econometrics, we focus on the geographical dimension of economic convergence of African countries. This allows us to deal with spatial autocorrelation which is a consequence of econometric interdependences due to geographic spillovers. Indeed, countries economic performance hides specific geographical patterns providing information on the importance of location on economic dynamics. Our results prove the existence of convergence process in Africa through a …
Smart Cities and a Stochastic Frontier Analysis: A Comparison among European Cities
2013
The level of interest in smart cities is growing, and the recent literature on this topic (Holland, 2008; Caragliu et al., 2009, Nijkamp et al., 2011 and Lombardi et al., 2012) identifies a number of factors that characterise a city as smart, such as economic development, environment, human capital, culture and leisure, and e-governance. Thus, the smartness concept is strictly linked to urban efficiency in a multifaceted way. A seminal research for European policy conducted by Giffinger et al. (2007) defines a smart city on the basis of several intangible indicators, such as a smart economy, smart mobility, smart environment, smart people, smart living, and smart governance. These authors’ …
On the link between urban location and the involvement of knowledge intensive business services firms in collaboration networks
2013
Knowledge intensive business services firms can play a key role in modern economies by linking localized collaboration networks to global knowledge flows, and by actively serving in support of knowledge diffusion across institutional and sectoral divides. The extent to which they do is dependent on the markets, partners and human resources available locally. This paper uses the unique establishment-level innovation data available in Norway to investigate whether location in urban labour market regions influences the geographical scope of collaborative linkages maintained within and outside the realm of clients. It proceeds to consider whether the diversity of partner types used locally, dom…
Ostacoli e determinanti dell’innovazione: un’analisi sulle imprese siciliane di successo
2010
Questo lavoro intende contribuire ad ampliare la precedente indagine Res sull’innovazione in Sicilia, soffermandosi in particolare ad analizzare i principali fattori di ostacolo alla realizzazione di innovazioni. In generale, le nostre elaborazioni mettono in evidenza l'esistenza di elevati livelli di percezione delle barriere territoriali esterne imposte dalle carenze del contesto (infrastrutture, pubblica amministrazione, servizi alle imprese etc.). Tuttavia, le nostre stime fanno emergere l’importanza delle barriere economiche e delle barriere relazionali nel determinare soprattutto le innovazioni di processo. Un altro risultato della ricerca sottolinea l’elevato grado di interdipendenza…

MEASURING REGIONAL CONVERGENCE - AN APPLICATION TO THE EUROPEAN UNION AND ROMANIA
2012
Attention of regional economic convergence has a great place in economics literature. The application of spatially explicit methods of data analysis to the convergence question has yielded important insights on regional economic growth. The literature on regional income inequality, although somewhat older than the convergence literature, has been slower to adopt new spatially explicit methods of data analysis. Application of recently developed methods of spatial econometrics to the question of regional convergence has yielded a more comprehensive and multidimensional view of regional economic growth. This article aims to identify the techniques and methods use for regional convergence and i…
