Urban competitiveness is the concentrated embodiment of regional comprehensive development ability. Focusing on the evaluation of urban competitiveness is of great significance to grasp the law of urban development and scientifically explore the construction of innovative cities. In nine cities in Fujian province for the research sample, to capture the economic development, social undertakings, public infrastructure construction, ecological environment four dimensions of statistics to establish urban competitiveness evaluation system, using the factor analysis of the 24 variable index evaluation system factor extraction and rotation, and to measure the relevant public factors, and the final empirical analysis of the research samples.The study found that the indexes of 9 prefecture-level cities in Fujian province showed significant intercity differences, and the siphon effect of Fuzhou, Xiamen and Quanzhou was more obvious, among which Xiamen was the most obvious. The ranking of the ecological environment level and the calculation results of the other levels is inverted. In terms of spatial distribution, the ecological environment quality of the northern cities in the province is generally better than that of the southern cities. In the future, the coordinated development mechanism of urban agglomeration with "combining points and combining points and areas" is a more appropriate modern urban agglomeration governance model.
