Flow space reveals the urban network structure and development mode of cities in Liaoning, China

Abstract

As an important supplement to “location space”, “flow space” has become an important trend in urban network research. At present, the theoretical basis and empirical research of urban network structure from the perspective of “flow space” are not completely clear. Based on the urban spatial network structure research system framework, this paper comprehensively studies the urban spatial structure, spatial network pattern and development mode of Liaoning Province in China by using multivariate data flow. The results show that: (1) Cities at all levels in Liaoning Province have different functions and roles in the urban network level, with Shenyang and Dalian as the leading cities, and Anshan and Jinzhou as “transit hubs”; (2) Liaoning Province takes Shenyang-Dalian as its main axis, the Shenyang economic circle with Shenyang as the core and the coastal economic belt with Dalian as the core and Dandong and Yingkou as the two wings intersect to form the urban spatial network pattern; (3) In the future, Liaoning Province should further form the urban development model of “core city-axis-cluster”. Under the trend of globalization, it should carry out in-depth promotion in combination with “Shenyang Modern Metropolitan Circle” “Liaoning Coastal Economic Belt” and “Liaoning Northwest Strategy”, and finally form a balanced, efficient and comprehensive urban network structure.

Spatiotemporal characteristics and driving mechanisms of coupling coordination of pseudo human settlements in urban agglomeration in eastern China

“…At the beginning of the 21st century, "pseudo-settlements" were introduced into "Human Settlements Geography(HSG)", and the concept of "PHS" was put forward, i.e., a kind of information and mimicry settlements constructed by the residents based on their own will and cognition, taking the reality settlements as the "base plate", through editing and processing, and with the help of the media 7 . With the advent of the informatization era, the importance of the information environment is increasingly prominent 9 , and PHS has gradually captured the attention of geographers. Existing research on PHS focuses on four main areas: (1) content studies, mainly addressing the de nition of the PHS concept 7 , the characterization of its spatiotemporal evolution 10 , and realistic features and driving mechanisms 11 ; (2) relevance studies, which concentrate on the coupling coordination with the RHS 12,13 ; (3) scale research, primarily considering the provincial scope 10 as the research object.…”

Evolution of China’s Coastal Economy since the Belt and Road Initiative Based on Nighttime Light Imagery

“…The downturn before 2018 is the result of combined influences, including inadequate policy implementation [55] and the deficiency of industrial structure transformation [56]. After 2018, with the in-depth implementation of policies, such as the "Shenyang Economic Belt" and "Liaoning Coastal Economic Belt", Shenyang radiates to the surrounding cities and promotes development [57]. The economic growth of the other two sample areas, the two most developed urban agglomerations, showed a trend of first growth and then decline, with 2018 as the turning point (Figure 4b,c).…”
