通过利用变异系数法对1989-2012年山东省地区经济差距演变的统计分析和利用Theil指数法对差距来源的结构分解表明,山东省地区经济差距呈现倒＂U＂型变化轨迹,以东部内部差距为主导的地带内差距和以第二、三产业为主导的产业内差距,构成了1989-2012年山东省经济差距的主要地带来源和产业来源,地带间差距和产业间差距仍不可忽视。根据实证结论,建议政府部门在依地区要素禀赋调整产业布局、促进优势企业跨地区扩张、提高对落后地区的教育扶持等方面加强宏观政策调控,以兼顾地区经济平衡与产业结构优化。

英文摘要：

This article firstly employed variation coefficient to analyze the evolution of regional economic gap in Shandong province from 1989 to 2012,and then used Theil entropy to statistically decompose the gap sources and composition.Study demonstrated that：1） Regional economic gap in Shandong has appeared as an inverted ＂U＂ type trajectory during 1989-2012,specifically divergence in 1989-2003 and convergence in2004-2012.In addition,the regional economic gap in final observation phase was greater than that in the beginning phase.2） From the zone-gap composition,intra-zone gap was the main source of regional economic gap in Shandong,accounting for more than 80% of it each year,even 85% in 1989-2004.Among the intra-zone gap,contribution was mainly from east and west zone of Shandong,of which more than 44% from eastern Shandong each year and over 31% from western Shandong in 1989-2009.While contribution from inter-zone gap declined year by year,it was 19.17% in 1989 and 14.34% in 2012.Therefore,internal gap in the east zone dominated intra-zone gap and constituted the major zone gap source in Shandong Province.3） From the industry-gap composition,regional economic gap of Shandong mainly came from intra-industry gap,whose contribution to regional gap has been more than 56% each year,and exceeded 80% after year 1998.Among the intra-industry gap,the secondary industry and the tertiary industry constituted the major source,contribution from the secondary industry has exceeded 50% in 1989-2004,and that from the tertiary industry increased and has been more than 40% after 2010.Contributions from the three industries and inter-industry gap to regional economic disparities have shown certain characteristics of time variation.Firstly,primary industry in Shandong Province contributed little,though contribution rate in 1989-1991 was slightly higher.Secondly,influence of the secondary industry in 1989-2009 was dominant,but since 2005 the contribution has tended to decrease.Thirdly,the tertiary industry＇s contribution sh
