摘　　要：笔者以昌九一体化中17个区县为研究对象,从2014年《南昌市统计年鉴》和《九江市统计年鉴》中获得各研究对象的GDP和非农业人口数量,利用车次网数据获取城市间最短公路里程,将数据运用至修正后的城市间经济联系引力模型中,分别计算出城市间的经济联系值。采用社会网络分析法(SNA),从网络中心度、整体网络密度与结构、凝聚子群和结构洞等角度分析城市间网络结构的经济联系。通过研究,得出了以下结论:1除少数几个核心城市经济联系较强外,其他均较低,资源利用效率有待提高;2昌九一体化城市群各城市之间经济联系较为紧密,但与发展速度极快的一线城市相比,仍有很大的提升空间;3核心城市以经济领导者角色带动辐射输出、接受辐射以及输出和接受程度都较低的普通城市,促进一体化的共同发展;4核心城市出现了结构洞,具有资源和信息上的极大优势。笔者据此提出一带一路战略下昌九一体化进一步发展的政策建议。GDP and non - agricultural populationof 17 counties in Chang - Jiu integration area were extracted from Nanchang and Jiujiang Statistical Yearbook of 2014. Through transport network, minimum highway mileage between cities was obtained and then value of economics connectionwas calculated. We analyzed network structure of city economics ties from network center, overall network density structure, condensed subgroups and structure holes by using social net- work analysis. Through data analysis, we drew the following conclusions ： （ I ） Despite strong economics connection among a few core cities, other lower economics connection cities should improve resource using efiqciency. （2） The economics connection between cities of Nanchang to Jiujiang integration has been improved, but there was more to improve when com- pared to other first - tier cities. （3） Core cities should play as a leadership role to promote low output ordinary cities into the integration of common development. （4） Under the Belt and Road strategies, we put forward further development pro- pose of Chang - Jiu integration by recognizing great advantages of resources and information due to structure hole, which would provide supports for its further development.
