This article analyzes the Guanzhong-Tianshui economic zone and the core area of the overall social and economic development,the use of fragmentation index method,linear regression analysis of Guanzhong-Tianshui economic zone spatial agglomeration and fragmentation measure and trend forecast.Research shows that the establishment of the economic zone promotes the harmonious and stable growth of the economy,the urban development of the whole economic zone has the trend of homogenization,and the growth of the core area is not the effective growth pole.The economic development of the whole city is not obvious,but the degree of fragmentation in the core area is higher than that in the economic area.The different development degree of the whole city in the core area and the economic zone confirms that the city fragmentation development is influenced by many factors,such as policy,resources and geographical location.In order to promote the Guanzhong-Tianshui economic zone harmonious and efficient development of the core area,to actively promote the development of the surrounding area,the surrounding city should make full development and utilization of logistics and economy the information platform,strengthen exchanges and cooperation with the core area relocation or the talents and information exchange with other city,to further enhance the development ability of the economic zone,gradually narrowing the regional differences in development,and promote the healthy and efficient development of Guanzhong-Tianshui economic zone economic society.%通过分析关中-天水经济区整体及核心区社会经济发展现状,运用碎化指数法、线性回归分析法对经济区的空间集聚与碎化进行测度与分析.结果表明,经济区的建立促进了经济的和谐稳定增长,经济区整体城市的发展呈现均匀化,没有形成有效的增长极;而核心区城市的发展也以碎化发展为主要趋势,与经济区整体相比表现得不显著,但在空间面积内核心区的碎化程度均高于经济区整体;核心区与经济区整体城市的不同发展程度证实了城市碎化发展受多种因素的综合影响,如政策、资源和地理位置等.为促进关中-天水经济区的和谐、高效发展,核心区要积极主动带动周边地区的发展,周边城市也应充分发展与利用物流、经济信息平台等,加强与核心区的交流和合作,逐步缩小地区间发展差异,促进经济区经济社会的健康高效发展.
