摘 要 本文选用引力模型方法，对沿长江经济带三大城市群（成渝城市群、长江中游城市群以及长江三角洲城市群）地级市间经济联系的空间特征分别进行了分析，并且在他们三者之间进行了比较。最终结果显示：这三个城市群在经济联系的强度、方向、范围等方面都存在一定的差异。在经济联系强度上，长江三角洲城市群和长江中游城市群地级市的经济联系强度要强于成渝城市群的地级市的经济联系强度，而且前两个城市群中对外经济联系总量最大和最小的地级市间的差别较大，而成渝城市群中这两个的差别相对较小；在经济联系方向上，距离对于三个城市群各地级市对外经济联系的影响作用都最为突出，行政区划的影响作用在三个城市群地级市对外经济联系中的作用不同，其对长江中游城市群地级市的经济联系影响最为强烈，三个城市群经济联系方向上都有中心指向性，长三角城市群的经济中心较多且具多样性，而长江中游城市群都以省会城市为主；在经济联系范围上，长三角城市群经济联系的辐射源较多，净辐射性城市数量多于其他两个城市群且辐射范围较广，成渝城市群净辐射性城市最少，辐射源也最少。 该论文有图 6幅，表 9个，参考文献11篇。 51099

毕业论文关键词：长江经济带 城市群 经济联系 引力模型Analysis of Economic Space along with the Three Major Cities in the Yangtze River Economic Links Groups Abstract This selection of the gravity model approach, the spatial characteristics of the three major cities along the Yangtze River economic belt group (group of Chengdu-Chongqing city, the middle reaches of the Yangtze River and the Yangtze River Delta City Group City Group) among prefecture-level city economic ties were analyzed separately, and their three between compared. Final results showed that: the three urban agglomerations in intensity, direction, range and other aspects of economic links there are some differences. On the strength of economic ties, economic ties strength Yangtze River Delta city group and middle reaches of the Yangtze River City Group level city economic ties stronger than the strength of Chengdu-Chongqing Urban Agglomeration of the prefecture-level city, and the maximum total amount of foreign economic ties with the former two urban agglomerations and among the smallest prefecture-level cities vary greatly, and the Chengdu-Chongqing urban Agglomeration these two differences are relatively small; in the direction of economic ties, from the influence of the three urban agglomerations around the city level foreign economic ties are the most prominent role in the influence of different administrative pisions in urban agglomerations three prefecture-level city in the foreign economic links, their economic ties on the middle reaches of the Yangtze River city group prefecture-level city of the most intense, three urban agglomeration economic links have direction center directivity, the economic center of the Yangtze River Delta city group possessed more persity, and the middle reaches of the Yangtze River city group are based in the capital city; in the range of economic ties, the radiation source of the Yangtze River Delta economic ties more net radiation the number of cities and urban agglomerations of more than two other wide range of radiation, net radiation Chengdu-Chongqing urban Agglomeration urban least, the least radiation.
