摘要
选取了1990—2003年反映经济发展水平的GDP、人均GDP等指标，采用标准差，变异系数对山东省内经济发展的绝对差异、相对差异进行分析，同时运用重心测度公式，分析了山东省10多年来经济重心转移的空间变化．结果表明：山东省东、中、西3大地带与17地级市（地区）发展的绝对差异、相对差异总体上呈现出拉大的态势；地级市（地区）之间的差异程度较之3大地带间更为显著；依据人均GDP与全省平均水平的比较，利用2003年的数据，将山东省内107个县、市（区）经济发展水平划分为4种类型：山东省经济重心位于几何重心偏东，且东、西偏移波动大．
This paper selects GDP and PGDP indexes reflecting economic development in Shandong Province from 1990 to 2003, using Standard Deviation and Coefficient of Variation to anahze the absolute difference and relative differene on economic development in Shandong Province. the center of gravity on economy is used to measure the changes of location in the last more than 10 years. The results indicate： the economic disparity of three regions and 17 central cities, whatever on absolute difference of relative difference, is enlarged except 1997＇ s fluctuation; and the disparity degree on 17 central cities is more obvious than the three regions. According to the comparison on PGDP and the average PGDP of Shandong Province. 107 cities are divided to four category types. The center gravity of economy lies to the east of center of Shandong Pronvince, and it is changing from west to east frequently.
