  • With Professor Qisheng Pan, Texas Southern University
  • Dow Science Complex 270
  • 12pm
The event is free and open to the public.  Food and refreshments served.

There is little empirical literature that examines the emergence and growth of employment centers in large metropolitan areas. However, only a few of them study the determinants of center growth over time. Even fewer studies, if any, compare different regions on how their employment centers grow or decay over multiple decades. This research aims to fill the gap in the empirical literature by exploring the change of employment centers for decades in two largest metropolitan areas with comparable size, i.e. Houston and Dallas. It employs the 1990 and 2000 Census Transportation Planning Package (CTPP) data and American Community Survey (ACS) 2006-2010 5-year estimates for testing the factors in the literature that are considered to affect the emergence and growth of employment centers, including physical characteristics, industrial configuration, and accessibility to or location of the centers. A revised two-stage minimum cutoff point approach is utilized to identify employment centers. A step-wise regression method is adopted to find the major contributors to the changer of employment centers. A traditional ordinary least square (OLS) regression model is employed to report the relationship between the changes of employment subcenters and their major contributors. Based on the results, it is possible to identify the change of employment centers and also to understand the major drivers of change. The findings would be valuable for urban planners and policy makers for allocating resources towards transportation, logistics, and urbanization infrastructure, as well as to businesses for identifying crowd-in centers and emerging markets.

Dr. Qisheng Pan is Professor and Chair of the Department of Urban Planning and Environmental Policy at Texas Southern University. Dr. Pan's research focuses on multiple aspects of urban planning, including transportation planning, economic impact analysis, and the applications of GIS in urban planning. He has received research grants from Texas Department of Transportation (TXDOT) to measure access to public transit services and to examine port-related traffic and emissions. Recently, he received research grant from the Ewing Marion Kauffman Foundation to examine agglomeration impacts on entrepreneurial ecosystems. He has also consulted in multiple research projects from National Science Foundation, Department of Homeland Security, Department of Transportation, and RAND Corporation, etc. Dr. Pan served as the Chair of the Board of Directors (BOD) for the International Association for China Planning (IACP), 2013-2015. He was also a BOD member for the Association of Chinese Professional in Geographic Information Sciences (CPGIS), 2013-2015. Dr. Pan received a Ph.D. in Urban Planning and a Master's degree in Computer Science from the University of Southern California (USC). He also holds a Master's degree in Cartography and Remote Sensing and a BS in Geology from Peking University. Webpage: ​
