The former three chapters are about theoretical research, and the forth chapter is about empirical research. The theoretical research part generalizes the theoretical basis, theoretical model and the concept of city competitiveness both at home and abroad. According to these theories, the paper introduces the complete and explicit definition of city competitiveness and brings in a new city competitiveness model .The paper emphasizes on empirical research using the data in 2004 as sample, whose objects are ten big cities:Guangzhou, Shenzhen, Tianjin, Shenyang, Dalian, Nanjing, Hangzhou, Wuhan, Chongqing and Chengdu. Firstly, on the basis of mean square deviation method, it finds out both the scores of integrated competitiveness of cities and other factors, based on that analyze the relationship between them. And then the paper computes the scores of competitiveness of cities above by principal component analysis and sorts out them for assessment.
