On Indicators Oecd Proposes for Gauging Science & Technology

The great number of theories of technological change witnesses a difficulty in devising and performing the crucial experiments which would allow a ra- tional choice among alternative explanations. A preliminary step of the methodological process that must be completed to overcome such difficulty is the construction of consistent taxonomies of the S&T Indicators available to test current theories. By rationally defining sound criteria for the measure- ment of S&T activities, a well-founded taxonomy like that will provide schol- ars with clearer and better analytical instruments for theoretical discussion. As a consequence, the empirical investigation, which always ought to be closely linked with theory, could improve as well.
