| Abstract: |
| In the research of urban spatial capacity generation, the theory of space production has
the most profound insight. It reveals the political and economic institutional attribute of space,
takes space as a means of production and productivity, and participates in the shaping of cities by
political and economic factors such as capital, political power and hierarchy. Examining China's
rapid urbanization process with the theory of spatial production, the added value from the land
development, construction and operation is closely related to the generation of spatial capacity,
which has become a key issue in urban development.
After the reform and opening up of Chinese cities, in the process of urbanization and
industrialization, the implementation of land system, fiscal and taxation system and city
planning has made the field of urban construction presenting a super large-scale space
production over 40 years. When the city changes from incremental expansion to stock renewal,
the generation of spatial capacity lies in the dual constraints of growth restriction and economic
feasibility.
Overall, relying on the space construction to add the city value is unsustainable for
the future development. With the slowdown of population growth rate and the urbanization
process, the total amount existing built space in the cities has filled the requirement from the
urban future development to a considerable extent, and even some cities have been seriously
oversupplied. Coupled with the profound evolution of urban industrial functions, the impact
of the internet economy and the epidemic have led to the low efficiency and idleness of urban
space.
From the medium and micro perspectives of project implementation, because space
capacity is the essential factor for the generation and distribution of the profit in urban
construction and operation, the urban renewal still employs the traditional development path
and institutional mechanism. The space construction drives profit growth more efficiently than
does space operation. In addition, it is a common way to protect the public interests by heading
part of the land or the construction to the government in the renewal project. They could be
used to supplement the deficiencies in the old development and provide new public services,
which also increase the operation cost to be balanced in the renewal.
A study to Beijing renewal cases could unveiled the growth of various spatial capacity by different means to increase value, compare the governmental income from land transfer fee and spatial incremental reduction by various modes, such
as, land collection and storage bidding, auction, land agreement transfer or independent renewal. The data are showing at the existing development
situation, the trend from space construction to space operation is inevitable.
In this transition process, the following issues deserve further discussion: 1) Although the spatial capacity of urban renewal is facing increasingly
urgent growth constraints at the macro level, for some urban areas with sustainable development power, the value adding mode of spatial construction and
spatial capacity growth will exist objectively for a long time. A rational restricting spatial increment and actively improving spatial efficiency are important
concerns in making policy. 2) How to release the renewal power and protect the public interest by coordinating land, finance and taxation and city planning
system is the key in the process of urban renewal management. At present, there are still many works to connect planning management to the corresponding
land finance and taxation systems. 3) It is worthy to explore the path to capture the value to the surrounding environmental development from public
facilities, so as to form a circulation to recycle the gain to ensure the public interest and a sustainable development of the city. At the same time, the policy
optimizing the usage of the stock space and improving the space utilization efficiency need to explored. |
