Existing literature on China's urbanization focuses primarily on the expansion of cities and towns, with little attention being paid to urban renewals. The wasteful use of urban land has conventionally been attributed to the ambiguous definition and ineffective protection of property rights. This study examines recent practices in urban redevelopment in Guangzhou – a site chosen by the central authorities to pilot urban renewals (sanjiu gaizao). The research identifies a local practice in which institutional changes are made not in the delineation of land property rights but instead in the redistribution of the benefits to be made from land redevelopment. Current users of the land are offered a share of the land conveyance income previously monopolized by the state as an incentive to encourage them to engage in urban renewal. Land-use intensity and efficiency have increased, along with social exclusion and marginalization. Research findings cast doubt over the perceived notion that the uniform and unambiguous definition of property rights is the prerequisite for improved land-use efficiency and call for a critical evaluation of the current urban renewal policies that completely ignore the interests of the migrant population who outnumber local residents by a large margin.
