Abstract
Economic strength has always been an important indicator for assessing a country or a city. In this paper, we select 15 economic indicators to evaluate the comprehensive economic strength of 21 prefecture-level cities in Sichuan Province. Through factor analysis, these indicators were grouped into three aspects: urban production capacity, residents' living standard and urban land area constructing an evaluation system for the comprehensive economic strength of prefecture-level cities in Sichuan Province, and based on the factor scores, we arrived at a ranking of the comprehensive economic strength of prefecture-level cities in Sichuan Province, which showed that Chengdu scored much higher than other cities. What’s more, through cluster analysis, we divided the 21 prefecture-level cities in Sichuan Province into four categories, and made suggestions to promote the economic development of the Sichuan region based on the evaluation results.
