Applying rough set theory in evaluating the competitiveness of Modern service industry in Guangdong province

In this paper, we make an attempt to introduce rough set theory into an evaluation modeling approach of modern service industry competitiveness. Since its proposal in 1982 by Z.Pawlak, rough set theory has already been successfully applied to a series of research domains. Surprisingly however, the approach has never been applied to modeling industry competitiveness evaluation. In this paper, we design the evaluation index system of modern service industry, build a comprehensive evaluation model based on rough set theory and evaluate the competitiveness of modern service industry in Guangdong compared with the other 13 provinces and cities in China. We further point out the existing problems of the development of modern service industry in Guangdong province and put forward some suggestions.
