利用1978-2007年的统计资料,对30年来山东省17地市的经济差异进行动态对比。选择标准差测度区域经济的绝对差异,选择加权变异系数、基尼系数度量区域经济的相对差异,根据时间序列多变量指标对山东区域经济增长差异的收敛性进行多维非线性分形R/S分析。研究表明,山东区域发展差异演变具有明显的分形特征,没有收敛(趋同)而表现为较强的发散性(趋异),而且这种发散性在短期内有进一步加强的趋势。
Using the statistical data from 1978 to 2007, the economic differences of 17 cities in Shandong Province over the past 30 years were dynamically compared. We choose the standard deviation to measure the absolute difference of regional economy, select the weighted coefficient of variation, and Gini coefficient measure the relative difference of regional economy. According to the time-series multivariate indicator, we make a multi-dimensional nonlinear R / S analysis on the convergence of regional economic growth difference in Shandong. The research shows that the evolution of regional development in Shandong has obvious fractal characteristics, showing no divergence (convergence) and strong divergence (divergence), and this divergence tends to be further strengthened in the short term.
