Abstract
Employing coupling coordinatio
research attempts to reveal the i
between built-up land expansio
social-economic (
DSE
) urbanization in Shanghai–Hang-
zhou Bay (
SHB
) Metropolitan Region. It first compared the
development trends of four elements, including built-up
land expansion level, demographic urbanization, social
urbanization, and economic urbanization from 1994 to
2015 through descriptive statistics. Then
CCDM
was used to
identify the spiral escalation trend relationships between
built-up land expansion and demographic/social/economic
urbanization, respectively. The findings revealed that the
degree of coupling coordination between
BLE
and
DSE
ur-
banization had the trend to ascend in
SHB
, and Shanghai
has a more superior balanced development tendency than
other cities. It concludes that
CCDM
can be implemented
as an effective approach to evaluate the coupling relation-
ship, and the related agencies in
SHB
can strengthen the
coordination to provide suggestions and make decisions
for the coordinated development of urban agglomeration.
Introduction
China has been experiencing a rapid urbanization process,
which is characterized by strong built-up expansion, extreme
urban population growth, and unprecedented social-eco-
nomic development since the 1990s. During the last several
decades, urbanization emerged in the developed areas, where
urban construction and development were vigorous, and
land use in these regions experienced significant changes
and restructuring. Under the force of administrative measure
and land finance, China’s urbanization is in a stage of fast-
forward and uncontrolled spatial sprawl, leading to illusory
high population urbanization (Qi
et al.
2016), high housing
prices (Wang
et al.
2017a; Li
et al.
2017), disorder expansion
of built-up lands (Li
et al.
2014), environmental degradation
(Wang
et al.
2017b), huge farmland encroachment (Chien
2015), increasing conflicts between human and land (Ma
et
pecially the cities in the coastal eco-
the preferred destination for millions
d overseas investors, have been the
ing China’s economic growth (Chen
et al.
2000; Wu and Zhang 2012). However, the unbalanced
disposition of human and land in coastal zones may threaten
the healthy development of urbanization. How to coordinate
the relationships among built-up land expansion, popula-
tion growth, and social-economic development is one of the
most important issues that China should face during the new
urbanization process.
Urbanization involves an array of interactive processes such
as demographic, social, and economic. How China’s urbaniza-
tion has been influenced by the built-up land expansion in
the eastern coastal region is certainly a significant issue that
needs to be explored and addressed. Related existing research
is largely dedicated to identifying the urbanization’s impacts
through the aspects of spatiotemporal changes of built-up land
expansion (Chuai
et al.
2015; Ianos
et al.
2016) and driving
forces and their interactions of built-up land expansion during
the urbanization process (Ju
et al.
2016; Liu
et al.
2017). Others
built models to analyze the interaction relationship between
population growth and urban expansion (Marshall 2007; Deng
et al.
2008). However, comprehensive studies on the coupling
coordination relationships among expansion of built-up land,
planning policies, and demographic-social-economic urbaniza-
tion in the metropolitan regions are relatively scarce.
The concept of coupling coordination is oriented from
physics, which refers to two or more systems that may
influence one another through a variety of interactions (Li
et al.
2012). Coupling coordination degree was employed to
analyze the interaction within systems, since it can reflect
to what extent the development of systems is coherent and
harmonious when comparing its value of two different sub-
systems. Coupling coordination model has been applied in
geographic studies, such as urbanization and environment
(Fang and Wang 2013; Guo
et al.
2015; Wang
et al.
2014), eco-
economics (Lu
et al.
2017), tourism and environment (Tang
2015), urbanization and population (Tang
et al.
2017), and so
on. The interaction between the two systems can promote a
regional coupling coordination degree, which shows a spiral
escalation trend (Lu
et al.
2017).
