Abstract: |
With China’s urbanization rate exceeding 60%, urban development has begun to shift from
large-scale incremental construction in the past to a simultaneous focus on quality improvement
and renovation of stock and optimization of incremental structure. Urban renewal is an important
means of solving urban problems and promoting healthy and sustainable urban development, and is a
strategic hand for promoting high-quality urban development. By combing through the literature on
the relevant aspects of urban renewal, it can be found that although there have been more studies on
the transformation of urban renewal mode and the rational choice of renewal mode. However, in the
current practice, the choice of urban renewal model still lacks a certain degree of objectivity, mostly
focusing on economic interests, and lacks a comprehensive consideration of how to balance the
interests of all parties and realize multi-dimensional goals. Due to the lack of in-depth analysis of the
motivation for regeneration and objective basis for the selection of regeneration mode, the efficiency
of regeneration work is low, and the process of regeneration loses sight of the other side and
contradictions occur frequently. Therefore, analyzing the main drivers of urban renewal, proposing
the selection of renewal modes, and improving the objectivity of the selection of renewal modes are
important issues that need to be resolved urgently in urban renewal.
Through organizing and analyzing the studies on the drivers of urban renewal, it is found that
urban renewal is mainly driven by three forces: public force, government force and market force. At
the macro-level, these three forces often act on the land parcels in a dynamic way of superposition,
penetration, interaction and balance to promote the renewal; at the meso-level, although each land
parcel in the city is subjected to the three forces at the same time, there exists a clear difference, and
the one with the greatest intensity is the dominant force of the land parcel; and at the micro-level, the
superimposition of the influencing factors influences the strong and weak renewal motivation of the
land parcels. The micro level, the superposition of the effects between the influencing factors thus
affects the strength of the regeneration dynamics of the plot. There is a direct correlation between the
choice of renewal mode and the dominant force. Therefore, analyzing the dominant forces of urban
renewal is the basis for model selection.
Through research, it is found that the type of dominant force in urban renewal is influenced by a
variety of factors. This paper establishes an evaluation system that takes the dominant force as the type
of regeneration, and constructs a three-level evaluation index system of target level, criterion level and
factor level. In order to ensure the scientificity of the evaluation system, the factors affecting the power
of urban renewal are analyzed layer by layer from the three levels of public power, market power and
government power, taking into account the index system of the 2022 urban health checkup assessment
in the selection of evaluation index factors. After several rounds of screening, a total of eight factors
are selected from the dimensions of architectural space, environmental greening and public space to evaluate the public power; five factors are selected from the dimensions of regeneration income and regeneration cost to evaluate the market power; and four
factors are selected from the dimensions of planning matching degree and public welfare degree to evaluate the government power. The Delphi method and
hierarchical analysis method are used to calculate the weights of the evaluation factors and construct the evaluation index system.
On this basis, this study takes the old urban area of Danjiangkou City as an example to carry out empirical research, and divides the renewal units into
430 units according to the evaluation results. Taking these 430 units as objects, the study area’s land use nature, building functions, relevant planning and
development requirements and other factors are comprehensively analyzed, and 387 renewal units are finally identified. Based on the established evaluation
index system, the 387 renewal units were evaluated in terms of power types. The results show that there are 18 public force-driven units, 70 market forcedriven units, 125 government force-driven units, and 174 balanced power units. Based on the evaluation results, recommendations for the selection of renewal
modes are proposed for the different types of units. The study shows that the regeneration types of units based on the evaluation of power differences are an
important basis for the objective selection of regeneration modes, which is of great significance for the refinement of urban regeneration and the promotion of
the scientific implementation of regeneration planning. |
