In the past, China’s urban development mainly focused on incremental space. In the
context of strict protection of arable land and tight constraints on land resources, the traditional
growth model has become unsustainable. Systematic research on stock space planning and
governance is not only a national strategic requirement to support high-quality development, but also
an important task of scientifically planning the spatial pattern of land in the new era and promoting
the reform of the spatial governance system.
According to the existing practice, the planning and governance of urban stock space in
China was mainly carried out from two aspects: land management, and urban construction. Land
management is mainly aimed at improving the quality and efficiency of specific types of land, such
as idle land, inefficient land, etc. Urban construction mainly focuses on urban regeneration, that
is, optimizing and adjusting the functions and improving the quality of all urban built-up areas.
Through two aspects of work, China has accumulated a series of experiences in the planning and
governance of urban stock space, but there are also problems such as the complex definition and type
of stock space, the difficulty in forming unified standards for the evaluation and development and
utilization of stock space resources, the complex relationship between interest claims and property
rights involved, and the lack of systematic establishment of relevant governance systems.
According to the existing research, the research on inventory space under the old institutional
framework has been quite comprehensive, but after China enters the period of land space planning
and governance system reform, there is still a lack of relevant research and reflection on how to build
a systematic inventory evaluation, planning, utilization, governance methods and system under the
new institutional framework.
Based on past relevant work experience and research results, and combining common types
of land management and urban regeneration, this article believes that the stock space can be
summarized into seven types of land, including “three idle” and “four low”. “Three idle” mainly
refers to land approved but not provided, idle land provided but not under construction, idle land,
etc; “Four low” mainly refers to inefficient industrial warehousing land, inefficient residential land,
inefficient commercial land, and other inefficient land. In the context of tight resource constraints
and high-quality development, the focus of future incremental space is on “control”, while the
focus of inventory space is on “optimization”. Emphasis should be placed on “people” as the core
to promote the transformation of urban development patterns and land use patterns, and achieve the “five optimization” goals of inventory space resources, including structural optimization, efficiency optimization, benefit optimization, layout optimization,
and quality optimization. In addition, we should systematically construct a full process technical system from survey evaluation, delimitation of key units,
optimized utilization, and supporting systems.
In the survey evaluation and unit delineation process, the focus is on building a stock space survey and evaluation model based on multiple data
and indicator systems, focusing on the three major processes of evaluation standard construction, utilization survey, pattern recognition and verification.
Then the final determined pattern should be incorporated into the basic information platform for land space planning and the “one map” system. On this
basis, the scope of key units for stock space improvement is delineated. In the optimized utilization process, the key is to follow the basic principles of
continuous context, people-oriented, green development, gradual progress, multiple participation, and joint construction and sharing, and to construct
targeted comprehensive improvement methods from the aspects of spatial planning, policy mechanisms, and organizational models based on the different
characteristics of the “three idle” and “four low” inventory space, with implementation orientation. In the supporting system, the “stock” thinking should
be embedded in the entire process of land space planning and governance, focusing on strengthening the design of policies and systems related to stock
space in the five major links of investigation and monitoring, planning preparation, development and utilization, ecological restoration, and supervision and
inspection. Finally, combined with a typical urban case of Neijiang City, the aforementioned technical methods are verified through examples from aspects
such as inventory space evaluation process, inventory space reuse, safeguard measures, and policy mechanisms. |
