A Spatial Analysis of the Employment Structure of Floating Population in Big Cities:the Case of the Main City of Nanjing

Employment of floating population constitutes an important angle to examine China's urban spatial structure.This paper looks at the main city of Nanjing in this respect.First,it describes aggregate employment spatial structure of floating population,and to divide the employment concentration areas by means of density Index and proportion index;Second,it analyzes the employment spatial differentiation of floating population by means of factorial ecological analysis; Third,the paper identifies employment centers of floating population by means of global spatial autocorrelation coefficient and local spatial autocorrelation coefficient.
