Comportement de demande de TIC : une comparaison internationale


  • Gilbert Cette
  • Jimmy Lopez


Cette etude vise a apporter des elements d'explication empiriques sur les ecarts de diffusion des TIC entre pays industrialises, en particulier des pays du continent europeen vis-a-vis des Etats-Unis. Les donnees concernent onze pays de l'OCDE, sont macroeconomiques, annuelles et portent sur la periode 1981-2005. Plusieurs resultats originaux ressortent de l'analyse : (i) l'influence du niveau d'education et des rigidites de marches sur la diffusion des TIC se serait sensiblement modifiee. La correlation de la diffusion des TIC, positive avec le niveau d'education et negative avec les rigidites de marches, est croissante (en valeur absolue) puis se stabilise vers le milieu des annees quatre-vingt-dix; (ii) les estimations realisees aboutissent dans tous les pays consideres a une baisse (en valeur absolue) de l'elasticite-prix de la demande de TIC ; (iii) les estimations confirment une influence (positive) de la proportion des diplomes du superieur et (negative) des rigidites de marches sur la diffusion des TIC. Ces effets sont accentues quand la diffusion des TIC est deja importante.
