1982～2003年间中国科技人员重心动态变化特征分析

应用区域重心的概念和模型计算中国1982～2003年间科技人员重心位置.计算结果表明,中国科技人员重心始终偏离于几何中心,且呈现先向东移动,1989年后持续向西南方向移动的特征.与同时期不同产业GDP重心比较,反映出科技人员重心移动轨迹与工业重心移动轨迹趋同的特征,而与农业重心、第三产业重心移动轨迹无明显关联,表明改革开放以来中国工业对科技人员的吸引力最大,科技人员对GDP增长的贡献也以工业为主,农业及第三产业对科技人员的吸引和利用较弱.

ANALYSIS OF DYNAMIC EVOLVEMENT CHARACTERISTIC OF TECHNOLOGY POPULATION GRAVITY CENTER IN CHINA FROM 1982 TO 2003

Technology population gravity center is calculated with region gravity center model from 1982 to2003 in china. Results indicate that the technology population gravity center moves to east from 1982 to 1989, then to southwest after 1989 against the gravity of geometry center of China all the while. Compared with gravity center of the different industry production value at the same time, the movement of the technology population gravity center is accordant with the movement of the industry production value gravity center, but independent of the movement of agriculture production value gravity center and the third industry production gravity center. The above shows that industry development level is the main attraction to technology population. Technology population mainly contributes to industry production value. The development of agriculture and the third industry is weak to attract technology population.
