Abstract

A positive relationship between information technology (IT), productivity, and growth has been established at the aggregate level. What remain unclear are the mechanisms through which the effect operates at the level of specific businesses. Statistical agencies have developed indicators of businesses’ readiness to use IT (e.g. the IT infrastructure, diffusion of specific technologies), and some indicators on actual usage (e.g., purposes, frequency of use). The next phase is using those data to develop estimates of the impact of IT use. A recent study addressed this question using aggregate data for Organization for Economic Cooperation and Development (OECD) countries, and micro data (data for specific businesses) for Germany and the U.S. A second phase of that study envisions a series of two- and three-country studies making use of newly available micro data for roughly a dozen countries. This paper outlines one such study, a three-country project addressing the impact of IT use in Denmark, Japan, and the U.S. Each country recently collected new data at the level of specific businesses on the use of IT by businesses, and has conducted preliminary analyses of its own data. Each country also has different underlying market and institutional structures. The findings presented here are preliminary. They show that network information technology has a significant impact on labour productivity growth in United States. The next phase of this project will develop estimates of the impact of IT use based on these new micro data, developing and testing hypotheses that acknowledge differences among the countries in market and institutional structures. La relation entre les technologies de l’information (TI), la productivité et la croissance économique a été établie au niveau agrégé. Cependant, les mécanismes par lesquels l’effet se manifeste au niveau de l’entreprise restent à préciser. Les organismes statistiques ont élaboré des indicateurs de l’aptitude des entreprises à utiliser les technologies de l’information (p. ex. l’infrastructure des technologies de l’information, la diffusion de technologies particulières) et certains indicateurs de l’utilisation réelle (p. ex. buts et fréquence d’utilisation). L’étape suivante consiste à produire des estimations de l’impact de l’utilisation des technologies de l’information. Une étude menée récemment par l’OCDE visait à résoudre cette question en utilisant des données agrégées pour les pays membres de l’OCDE, ainsi que des microdonnées pour l’Allemagne et les États‑Unis. Une deuxième phase de l’étude de l’OCDE consistera en une série de projets, regroupant deux ou trois pays, réalisée au moyen de nouvelles microdonnées obtenues récemment pour une douzaine de pays environ. Le présent article décrit l’un de ces projets, destiné à évaluer l’effet des technologies de l’information au Danemark, au Japon et aux États‑Unis. Chacun de ces pays a recueilli récemment de nouvelles données sur l’utilisation des technologies de l’information au niveau de l’entreprise et procédé à l’analyse préliminaire de celles-ci. En outre, chaque pays se distingue des autres par sa structure de marché et sa structure institutionnelle. La prochaine phase du projet consistera à élaborer des estimations de l’effet de l’utilisation des technologies de l’information fondées sur ces nouvelles microdonnées, ainsi qu’à émettre et à tester des hypothèses qui tiennent compte des différences entre les structures de marché et les structures institutionnelles de ces pays.
