Abstract: Fuxin city, Liaoning Province of China, is a coal industrial city, which is in the economic and social transition period.Its social space has some different characters from other cities.Therefore, the study on social space structure of Fuxin has theoretical and practical significance.In the research process, questionnaire survey was used to get the first-hand data.Factor analysis, location quotient analysis and cluster analysis were introduced to analyze the social space structure of Fuxin.The main analysis process contains 3 parts:First, 5 principal factors of social space in Fuxin were extracted by using factor analysis, including:1) the poor, 2) the "in system" employees, 3) the former mining workers, 4) the private and individual practitioners, as well as 5) people living in old residential quarters and shantytown.Second, improved location quotient method was utilized to analyze the spatial agglomeration of each factor with the help of GIS mapping.It was found that the spatial distribution characteristics of 5 factors were different from each other obviously.Third, cluster analysis was performed to divide the social areas.The whole Fuxin contained 5 social areas, namely, 1) the "in system" employees community, 2) the "others-transition" former mining workers community, 3) the "self-transition" former mining workers community (namely the private and individual practitioners community), 4) shantytown to reconstruct and 5) the poor concentration area.In addition, a simplified model of social space structure was abstracted according to the spatial distribution of the social areas.Easy to see from the model, almost all the social areas have some relationships with the former mining workers, and the railway is a clear dividing line.Based on the above analysis, the article also discussed the formation mechanism of social space structure of Fuxin, considering that the transition of the former mining workers, separation of the railway, resources development stage, the economic transition of resources-exhausted cities, special ecological and environmental problems of coal cities, as well as institutional factors in vocational differentiation promoted the unique social space structure of Fuxin.Especially, the transition of the former mining workers is the most important factor.
