Research on the Theme Evolution and Transformation Logic of Urban Renewal Policies in China

Abstract

Taking 94 urban renewal policy texts as the research object, the LDA topic model is used to conduct topic identification and evolution of urban renewal policy texts and logical analysis of policy changes. Research findings show that China’s urban renewal policies can be divided into three stages: the nascent stage, the growth stage and the development stage, and the policy system is constantly evolving and improving. Eight major themes have been identified, namely infrastructure and renewal, urban planning and intelligentization, housing and urban renewal, national policies and urban renewal, resource-based cities and green development, urban and rural planning and ecological construction, real estate and rental markets, and sponge cities and community services. The intensity of policy themes shows different evolutionary characteristics at various stages. Policy changes also present the logic of change, which includes the reconstruction of policy goals, the innovation of policy tools, and the transformation of the driving forces of change.
