Resumen
We study urban residential land use changes by analyzing the massive migration and relocation of two typical social classes: employees in government departments (EGD) and urban demolition displaced households (UDDH). After the reform and opening-up of China that has taken place during the last 30 years, the residential land use of both the EGD and UDDH groups has been notable in terms of the changing urban landscape in China?s cities. A considerable number of studies highlight the large scale relocations of weaker groups usually through sample surveys at a microscopic scale, which sheds light on the relationships between market forces and government intervention and power. However, employees hired by state government departments and related branches (Shiye Danwei) have been neglected. Bridging the empirical research gap and using Chengdu as a case study, we compare residential relocations of EGD and UDDH groups in Chengdu. Our analysis based on field surveys conducted from 2009?2013 indicates that the relocations of EGD and UDDH are spatially agglomerated due to China?s unique dual-track mechanism driven by market forces and government power since the late 1970s. The study shows that most of the UDDH are migrated from urban centers to fringes, while a large number of EGD still agglomerate close to urban centers. Government interventions differentiate residential relocations of EGD and UDDH, and market mechanisms reinforce these relocations. Potential problems caused by the dual-track mechanism are finally discussed and summarized.
