- Abstract
The scarcity of land determines the inevitable trend of land resource utilization from "incremental expansion" to "stock development." An important carrier of urban production functions, industrial land is the key object for stock space development of districts and counties in the context of national land spatial planning. The government-led inefficient land repurchases and redevelopment model, which is usually adopted by large cities, is not a direct guide for small towns with financial constraints. In this study, the existing theoretical studies, and practical experiences on the redevelopment of inefficient industrial land, are sorted and summarized to avoid the fragmented limitation of previous studies focusing only on one link of the redevelopment of inefficient industrial land and to build a systematic evaluation and optimization path with wide application value for the performance of stocked industrial land in districts and counties.In practice, most provinces and municipalities rely on the results of special surveys of inefficient land in towns for identification. In terms of organizing the redevelopment of inefficient industrial land, it can generally be divided into three types: government-led redevelopment, independent redevelopment by the original land rights holders, and redevelopment with the participation of market entities. It can be specifically divided into district and county levels. The five main difficulties generally faced in the current work include: (1) the connotation of the exploitable potential of the stocked industrial land needs to be updated, and the identification is not efficient or comprehensive enough; (2) an integrated implementation framework from policy to operation guidelines has not yet been formed; (3) market entities are not willing to participate in the transformation upgrading and land replacement; (4) the government's land storage capital needs are large and beyond local financial capacity; and (5) relevant regulations and policies are not perfect. In this study, all aspects of the whole lifecycle of industrial land are examined, and all non-high-quality industrial space is included in the category of the exploitable potential of the stocked industrial land, which is divided into four categories: industrial land approved but not supplied, industrial land supplied but not built, urban inefficient industrial land, and rural inefficient industrial land. On this basis, a systematic framework for the optimal renewal of industrial land is constructed, which includes three parts: macro performance study, micro inefficiency type identification, and land renewal plan delineation. At the macro level, the industrial land is divided into industrial bases, industrial communities, and industrial zones according to the level and scale of the industrial park, and the performance of industrial land is evaluated in five dimensions: economic efficiency, land-use intensification, livability and accessibility, collaborative innovation, and ecological low consumption. At the micro level, a recursive judgment logic is established based on enterprise survey data, and five types of inefficient land are identified at each level: insufficient greening, low efficiency, poor quality, insufficient equity, and security warning. Then the quality and efficiency improvements of the "three levels and five categories" of industrial land are classified and guided. Based on the principles of "preserving the total amount, promoting the gathering, and improving the quality," multiple scenarios of inefficient land redevelopment — including "large concentration," "small gathering", and "small gathering + moderate park integration" — are explored in this study, and a full lifecycle management mechanism is proposed to provide a more realistic and operational reference for the wide renewal of industrial land at the district and county levels.The limitation of this study is that the operating mechanism and dynamic evolution law of the existing stock of industrial space, especially the mechanism of inefficient land, are not explored in depth. In addition, the realization of quality, efficiency, and sustainable development of industrial land must rely on the theories and methods of urban and rural planning, economics, geography, management, and other multidisciplinary integration, which need to be further improved in subsequent studies.
