Abstract: In the background of economic globalization,the city is an important part of a country. And the city competitiveness is more and more crucial for improving a nation's comprehensive competitiveness. In this paper, an assessing index system had been set up to evaluate the 18 cities' competitiveness in Sichuan Province,China covering 6 specific indicators and 30 variables. Besides,the cities' competitiveness of Sichuan in 1996,2000, 2006 and 2013 were evaluated by use of the principal component analysis. And,the effect of each principal component factor for urban competitiveness was concluded. Based on the conclusion,the time evolution of urban competitiveness was studied further. According to an overall score of city competitiveness of 18 cities,the general situation and the influence factors of the principal component were analyzed. And the cities were divided into four grades,in accordance with more than 0.5,0.5 to -0.5,-0.5 to -1.5 and less than -1.5 of city competitiveness scores. By the help of GIS,cities in different grades were drawn in the map of 18 cities in Sichuan with different colors,and the evolution situation of spatial differentiation of city competitiveness were expressed through four time sections. Inverse distance weighted interpolation effect had been worked out,which revealed the features and developing rules of spatial variation and spatial expansion of city competitiveness during 4 periods of time. The results show as follows:(1) by the principal component,the comprehensive city competitiveness of 18 cities during four time sections were calculated and sorted;(2) the influence factors of competitiveness continued to evolve in the city;furthermore,the competitiveness factors of cities in Sichuan were mainly based on the scale of economic development and the level of infrastructure,and the economical open level and the urban environment were complementary;(3) by studying the various influence factors of city competitiveness and the correct evaluation, it was advantageous to develop the city competitiveness for the correct orientation and long-term planning, so as to realize scientific development of city.

Key words: city competitiveness, principal component analysis, spatial variation, spatial interpolation, Sichuan Province
