Although by 1990 the efficiency of the Lithuanian researchers according to the Soviet criteria was rather high, the reorganization of the R&D system preconditioned a certain induction period, during which the increase of the activity indicators accepted in the international practice was rather slow. It is furthermost related to the number of scientific publications in the journals included into the databases of the Institute of Scientific Information (ISI), Philadelphia (USA), (Fig. 4). At present the increase of the number of publications is rather rapid: an average annual increase of the number of publications since 1995 is 11.7 %.
Figure 4. The number of ISI publications per one million of population.
Recently two Lithuanian scientific journals, i.e. Informatica (published by the Institute of Mathematics and Informatics) and Baltic Astronomy (published by the Institute of Theoretical Physics and Astronomy of Vilnius University) have been included into the ISI database.
A larger number of issues are published by several strongest institutions – the Institute of Semiconductor Physics, the Institute of Chemistry, the Institute of Theoretical Physics and Astronomy of Vilnius University, the Institute of Mathematics and Informatics, the Institute of Physics, the Institute of Biochemistry, the Institute of Biotechnologies and Vilnius University.
The largest number of scientific publications of the Lithuanian researchers is published in Lithuanian and foreign publications that are not listed in the ISI database.
The production of some enterprises applying high technologies that were generated by Lithuanian universities and research institutes successfully compete in the world market. There should be mentioned suchjoint- stock companies as ”SICOR Biotech”, ”Fermentas”, ”Ekspla”.
