Introduces the concepts of granulation, degree of structure divergence, degree of nestle up, center divergence degree and margin divergence degree, etc, by rough sets theory and knowledge base theory.

This paper studies the dynamic relation between the industrial structure and employment structure in Sichuan province by correlation degree, structure deviation degree and employment elasticity, based on describing the trend of industrial structure and employment structure evolvement since the opening and reform.

This article carries on the real diagnosis to the Jiangsu Province industry structure and the employment structure studies with structure deviation index.

We analysis the relation effect between the industrial development and the population employment in Jiangsu province by the indexes of the structure deviation and the employment elasticity.

This paper analyzes the relation effect between the industrial development and the employment in Shandong province by the indexes of the structure deviation and the tertiary employment elasticity.

Through the decompose with departure degree of structure and comparison,the paper studies the development of tertiary industry to enlarge employment in Yunnan, which expounds that the tertiary industry has great potentialities in employment.

But we ve also found from the analysis for the deviational range of industrial structure that the first industry deviational range is always positive,while the second and the third in.
