摘要
以GDP和人口数作为测度区域经济差异的变量指标,运用基尼系数、泰尔指数、变异系数及空间中心统计法、地带分离系数法,从时间维度及空间角度对环渤海经济区44个城市经济发展差异的演变趋势进行定量分析。结果显示:①环渤海经济区总体差异呈扩大趋势,第二、三产业收入对总体差异的影响程度加大,产业的地理集中效应大于产业的结构效应;②辽宁经济区经济发展水平决定了经济中心向辽宁方向偏移,而河北及山东经济区合力拉动人口中心向西南方向偏移;③地带内发展差异特别是河北经济区的发展差异是区域差异扩大的主要原因,地带分离系数以2008年为拐点呈现"U"型结构。最后提出促进河北地区的发展是环渤海经济区在今后的发展中的主要着力点,是实现区域经济均衡发展的关键所在。
From the angle of temporal dimension and spatial perspective , using the Gini coefficient, Theil index, coefficient of variation, and the space center Statistics act, regional separation coefficient method, taking GDP and population as variable indicators to measure regional economic disparity, this study chose 44 cities of the economic circle around Bohai Sea to make the quantitative analysis of the development of differences in the evolution of trends . The results showed： （1） the tendency of overall disparity in the economic circle around Bohai Sea is expanding, The income of the secondary and tertiary industries had greater effect the overall disparity .The geographic Centralization effect of the industry is greater than the structure effect;（2） The departure of the economic center depended on level of economic development in the Liaoning economic zone to, while Hebei and Shandong economic Zone pulled the population center towards southwest; （3） disparity development within the zone was the main reason for the expansion of regional disparity, especially the disparity development of Hebei economic zone, The separation index within the zone presented a ＂U＂ shaped structure and the turning appeared in 2008.The results show that to promote Hebei area is the main focus of the development of Bohai Sea Economic Zone. and is also the kev to realize the balance development of regional economy.
