Technological Specialization And Economic Performance In Oecd Countries, Mario Pianta, Valentina Meliciani
Mario Pianta
The paper investigates the growing sectoral specialization in technological activities of OECD countries (measured using patent data) and its impact on countries' innovative and economic performance in the 1975-1990 period. Aggregate indicators of sectoral specialization are introduced, showing the extent to which countries concentrate their innovations in few fields, or spread them across several sectors. A general positive relationship is found between the degree of specialization in technology and higher rates of growth, while specialization in electronics-related fields is not associated to better economic or technological performances. The position of individual countries in these patterns is also examined, showing that …

Measuring Technological Change Through Patents And Innovation Surveys, Mario Pianta, Daniele Archibugi
Mario Pianta
This article provides an overview of recent research using innovation surveys and patent data as indicators of technological activity. The conceptual and methodological problems of 'measuring' technology are discussed, with a classification of the types of information which can be drawn from patent databases and from surveys of both innovations and the innovative efforts of firms. The findings and the methodological strengths and weaknesses of such studies are reviewed, considering first the evidence at the firm level, second the analysis of the industrial structure and finally the evidence at the country level and the process of globalization. The overview shows …
