Measuring the impact of government intervention on the spatial variation of market-oriented urban redevelopment activities in Shenzhen, China

As urban redevelopment becomes an essential instrument for further urban development, the spatial outcomes of these redevelopment activities exert an increasingly profound impact on urban development. Unlike past statedominated urban redevelopment, current market-oriented redevelopment activities are becoming more active, while the government continues to play an important role through various forms of intervention. To optimise the development of urban space, a comprehensive understanding of the effect of government interventions on the spatial variations of market-oriented redevelopment activities is required. Against the background of Shenzhen's market-oriented urban village redevelopment, this study formulated a theoretical framework to identify the core government interventions in terms of urban planning, development intensity control, and decentralisation, and then analysed how they affect the market-oriented redevelopment activities from a spatial perspective. Ordinary least squares regression and geographically weighted regression models were employed to conduct an empirical analysis to measure the specific impact of diverse government interventions. The results show that the planned transport routes, public facilities, and density zones can effectively guide the urban village redevelopment projects towards the future core development areas of a city. The introduction and implementation of Shenzhen's decentralisation of urban redevelopment have promoted urban village redevelopment and have resulted in significant differences in redevelopment activities dominated by market forces across administrative districts. It provides practical implications for implementing proper government interventions for the sustainable spatial development of redevelopment activities.
