Measuring the 'information market(s)': a personal experience

摘要

This paper focuses on some fundamental methodological problems: how to define 'information markets'? What are suitable 'statistical units' to measure the activities in these markets? How to approach these units and to measure their activities (survey methodologies, problems of identification of statistical populations, statistical indicators, etc)? How to draw conclusions from the survey results? How to organise surveys of information services markets in different countries (with comparable results from country to country)? How to transfer the results of the market studies to the right people at the right time?
