Is there a knowledge deficit in e-business?

The paper builds on results from a study of the Portuguese computer and related activities services sector, in the last decade. Following a model that considers only. three basic economic resources-knowledge, technology and capital-the analysis concluded that the sector's value added was provided by the use of knowledge, 61%, by the use of technology, 23%, and by the use of capital, 16%. The value added by engineering was also computed and the result was 55%. A comparison between the evolution of work productivity and knowledge intensity, in the decade, resulted in the calculation of a continuous deficit of about 9% per year concerning the knowledge about the use of technology. The authors think that this conclusion also applies to one part of the knowledge required in e-business.
