中国十大城市群正在成为中国经济、科技、文化最发达的地区，成为了中国国民经济的十大支撑点，因此，研究中国十大城市群综合发展水平具有理论和实践上的重大意义。通过构建城市群综合发展水平评估指标体系，采用多层次因素分析与分类相结合的综合评估方法，对中国十大城市群综合发展水平进行了科学评估及比较，十大城市群综合发展水平呈现出四大集团的非均衡区域差异分布。同时分别提出了缩短领先型集团、挑战型集团、追赶型集团、后进型集团城市群综合发展水平非均衡差异的对策与建议。

英文摘要：

City cluster refers to a considerable number of cities with different qualities, types and rank scales gathered in a special region. Since the policy of reform and opening-up, with the improvement ofurbanizaiton level, the number and scale of city have been expanded to a further step. The city group will play an increasingly prominent role in pulling Chinese economy and a crucial role in the linkage of region development. Currently, the ten-city clusters include Beijing, Tianjin and Ji（Hebei pronvice）, the Yangtze Delta, the Zhujiang Delta, Shandong Peninsula, Bei Huan of Bohai Bay and Northwest coast ofHuang Hai, Central Plains, the middle reaches of Changjiang River, Westcoast of Straits, Sichuan and Chongqing, etc. And they are becoming the most developed areas in China＇s economy, science and technology as well as culture. For this reason, reasearch on the comprehensive developing level of the ten-city clusters is of significance. According to the statistic system and data in the paper, stratification planes have been established on the three aspects of total quantity, quality and current capacity, including 41 specific indexes which show the comprehensive development of city clusters at any level.The overall assessment method is adopted to scientifically appraise and compare the development level of the 10-city clusters in China. The findings tell that the integrative development is extremely unbalanced between the East and the Midwest, which indicate the east coast area is advanced while the west is relatively backward. Moreover, Among the ten-city clusters, the Yangtze Delta urban cluster is the most formidable core area of integrated development level, the Zlaujiang Delta urban cluster and Beijing and Tianjin and Hebei urban cluster are the developed area of integrated development level. The three biggest urban clusters are all to be located at the developed area along the eastern coast. However, the integrated development level of the mid-west urban cluster is relatively low.
