中文摘要：

基于山东半岛蓝色经济区2003年、2007年、2012年县域经济发展数据,利用基尼系数、主成分分析法和探索性空间数据分析法对经济区县域经济时空格局演变进行综合分析.结果表明：12003-2012年间蓝色经济区经济总体差异呈现波动性下降趋势.22003年、2007年、2012年的蓝色经济区县域经济呈现显著的空间正相关关系,经济区内存在高值、低值集聚现象,高值多集聚在以烟台、威海、青岛为中心的北部环渤海沿岸和南部黄海沿岸地区,低值多集聚在西北黄河三角洲区域和中部内陆地区.3蓝色经济区县域经济冷、热点区域空间格局在不同年份均出现一定程度的波动.4蓝色经济区经济差异格局演化驱动因素主要有四个方面：地理区位、政策与区域发展战略、资源基础和产业结构.

英文摘要：

The research of economic spatial pattern evolution has an important meaning for understanding regional economic differences,coordinating regional development and making the development policy.By using the data of economic development of Shandong Peninsula blue economic zone in 2003,2007,2012,and using the Gene coefficient,principal component analysis and ESDA,the temporal-spatial evolution of county economy in the blue economic zone was analyzed.The results show that：1The economic differences of the blue economic zone have a decreasing trend in 2003-2012.2The county economy of blue economic zone shows significant spatial positive correlation relationship in 2003,2007,2012.There exists a clustering phenomenon,the high value of county economy agglomeration in Bohai coast in Yantai,Weihai,Qingdao as the center of the north and the southern of Yellow Sea coast,and the low value of county economy agglomeration in the northwest of Yellow River Delta region and the central inland region.3 In different years,the cold and hot regional spatial patterns of county economy have a certain degree of volatility.4 The economic influence factors of the blue economic zone are divided into four aspects：geographical location,policy and regional development strategy,resources,and industrial structure.
