decade. This manifested In absolute growth as well as In the share of this category of workers In the total number of workers end employees engaged In the state end cooperative sectors of these countries' national economy. In 1970-80 the growth of this categoy of workers was 1901 In Roumanle~ ·1471 In the German Democratic Republic, 1461 In the USSR, 1421 In Bulgarian People's Republic, 1331 In Hungary, 1231 In Czechoslovakia and and 1091 In Poland. The highest growth rates of this Increment were observed In 1970-75. In the second half of the 70s the majority of the CMEA member-sates witnessed somewhat slower growth rates of the R&D personnel which Is explained by e general demographic situation In these countries. The share of R&D In the total number of people engaged In the state end cooperative sectors of the national economy of the CMEA member-states witnessed a constant growth during the pest decade. Significant Increase of this share was observed In Hungary (from 1.81 to 2.121), Romania (from 1.151 to 1.51), the German Democratic Re~ubllc (from 2.071 to 2.43J), the USSR (from 3.321 to 3.89J), end Czechoslovekfe·(from 2~61 to 2.851)~ As a rule, In the 70s In elI CMEA member States the number of scientific workers (the most creative pert of personnel engaged In R&D activities) was growing at higher rates than the total number of personnel engaged In R&D activities, which Indicates qualitative Improvement of the employment structure In R&D sphere. During the seme period there was also a considerable Improvement of qualification structure of scientific workers as a result of Increase of the share of persons holding doctor or candidate of ·sciences degrees. Dynamics of growth of number of sclentlf)c personnel by separate branches of science reflect to a certain degree the existing trends of science development, .goals and priority
