Query: The balance of knowledge flows   In analogy to the technology balance of payments, in this paper we propose a
possible way to set up a "balance of knowledge flows" (BKF), recording world
flows of knowledge within the scientific community. Adopting a pure
bibliometric approach, the "knowledge" traced in the BKF is that produced and
exchanged by the scientific community by means of publications and relevant
citations. A description of the theoretical foundation of such a tool is
presented together with its empirical testing over the scientific production of
four different countries. The BKF can be part of yearly reports of science and
technology indicators, aimed at informing research policy.
