摘要:
益沅桃城镇群的建设是提升益阳市的区域竞争力,形成湘北地区新的增长极的重要举措。以SPSS软件的主成分分析法测度益沅桃城镇群各部分的经济发展实力,并结合空间相互作用引力模型测算各城镇的经济联系强度及对中心城区的隶属度,以此定量分析益沅桃城镇群的基本经济情况。结果表明:益阳市区在城镇群中处于绝对的经济中心地位,沅江市、桃江县与益阳市区的经济差距较大,益阳市区的辐射带动作用有待提高;益阳市在区内的引力强度最高,桃江县因距离的邻近效应,引力强度和隶属度排在第二,沅江市因区位和经济独立性排在第三。
摘要(英文):
The construction of the town-group of Yiyang, Yuanjiang and Taojiang is an important measure to raise the regional competition, to make up the new economic growth in the northern Hunan area. Taking the SPSS software to survey the strength of economic development and linking the space gravitation interaction model to estimate the economic growth between the county towns and the Yiyang centre city. The order of the basic situation is Yiyang, Yuangjiang and Taojiang Towns.As the quantitative analysis the result shows that Yiyang City is the absolute economic center, which exists the economic gap between Yuangjiang and Taojiang. Of course Yiyang is larger and the leading role in the economic radiation. It is of the highest power of gravity. Taojiang County is near to Yiyang. The gravitational strength and degree of order membership is the second row. Yuangjiang City is the third. By analysis of the economic position of the urban agglomeration it can provide economic and rational development of the town order of Yiyang, Yuangjiang and Taojiang.
