Abstract: We present a new empirical approach for identifying sub-centers within urban areas and apply itto the São Paulo metropolitan area (SPMA). We use geographically weighted regressions (GWR)to overcome the limitations presented by previous methods, which rely on previous knowledge ofthe employment distribution and use arbitrary threshold values and band sizes. We find threeSBD in 2002 and only two in 2014, suggesting that SPMA is polycentric but presents only onebusiness core that concentrates more than 90% of all employees working in an SBD. We applythe widely recognized method of McMillen and Smith (2003) to our database and compare theresults. Our method is more conservative in identifying areas as sub-centers (SBD) and presentslower standard errors.
