“…Besides these, there are also qualitative factors, such as preferences for a certain job, school, supermarket, social habits, or the will to use public transportation instead of personal car. According to Halleux (2021) [1], polycentrism is achieved when a clustering of centres are sufficiently close to develop synergy through functional connections and, at the same time, sufficiently separated to avoid the merging of their labour markets. During the last decades, a trend of transformation of the monocentric regions into polycentric ones can be noticed.…”

“…In a polycentric structure, the spatial dimension plays a critical part from a geographical approach. This kind of structures can be viewed at different scales, as various authors emphasized [1]: local (inside a city), regional (a metropolitan area, a functional urban area, a county, a region), national or even international. In this article we are approaching the urban development centres compared to their adjacent regions.…”

Polycentrism, studied at any geographical scale, local, metropolitan or regional, represents a sustainable perspective of development regarding the settlements, employment and facilities systems. It is usual to find this kind of development in Western Europe, in contrast with the Eastern part of the continent. The context is an accelerated economic and demographic development of the main Romanian cities and of the communes adjacent to it, but unbalanced in relation to the nearby settlements. Socialist ideologies left their traces in the urban planning of cities built completely in the XXth century or through the systematization of historical centers and street configuration. The study areas that we chose for this paper are the functional urban areas of the main cities from Romania. We hereby study the distribution of the secondary nuclei within FUAs through a geostatistical perspective, using methods such as spatial autocorrelation and GIS tools. Among the explanatory variables that we take into account, there is the employment rate, number of commuters, density of facilities etc. The main issue that we are answering is whether these secondary centers have the potential to transform the FUA into a polycentric structure and therefore, to achieve an even economical, spatial and transport system development.

“…People are the main wealth of a place, and their spatial agglomeration and diffusion profoundly affect the evolution of the urban system and the regional economic and social development pattern [1][2][3][4][5][6]. From conceptions of urban decay and resurrection to legends of New York and London, the waxing and waning of the population has traditionally been used to proclaim the rise and fall of cities.…”

Population Dynamics and Its Driving Forces in China from 2000 to 2020

Exploring population dynamics and its driving factors has important practical significance for guiding reasonable population distribution. In view of this, this paper systematically analyzes the population dynamics and driving factors in China based on the latest three decennial censuses, using research methods such as the population concentration index, the center of gravity model, relative change in population density and multiple linear regression. The conclusions are as follows: (1) China’s population distribution is uneven, and the trend of polarization in population distribution is increasingly evident. The spatial differences in population growth are shifting from east–west to north–south. Under the influence of the “core–periphery effect”, more people are gathering in a few large cities. (2) The factors affecting population changes have obvious temporal variability: terrain and temperature have an increasing impact on China’s population changes. Temperature in particular has become an important factor in China’s population changes. Population changes are gradually shifting from being driven by a single economic factor to being driven jointly by social and economic factors. (3) The factors affecting population changes also have obvious spatial heterogeneity: temperature affects population changes in both the eastern and central–western regions, while terrain only affects population changes in the central–western regions. Currently, population changes in the economically developed eastern region are more driven by economic factors, while the central–western regions are driven by both economic and social factors. Central cities in the central–western regions are experiencing accelerated population agglomeration, while central cities in the eastern region are losing their ability to attract population agglomeration. The above conclusion basically clarifies the patterns and influencing factors of China’s population changes since the 21st century, which can provide a useful reference for future population development and regional planning.

“…Particularly in an era with an aging population and a low fertility rate, the changes in population have a more prominent effect on the variation in city size than ever before [3]. Understanding the distribution of population and its growth across hierarchies takes on great importance for forecasting the evolution of the urban system and determining socioeconomic trends [4][5][6]. To date, two strands in the literature have been identified to uncover the pattern of population dynamics among cities: the upward pattern and the downward pattern.…”

The Spatial-Temporal Evolution of Population in the Yangtze River Delta, China: An Urban Hierarchy Perspective

The reason for changes in ranking within urban systems is the subject of much debate. Employing the census data from 1990 to 2020, this paper investigates population dynamics across urban hierarchies and its influencing factors in the Yangtze River Delta. The results reveal an upward pattern of population dynamics and show that the advantages of high-ranking cities in population gathering are obvious, though they have declined recently. Based on a framework of urban amenity and the ridge regression model, the authors argue that concerns of residents in choosing cities in which to settle are gradually changing from economic opportunities to multidimensional amenities, finding that the influencing mechanisms vary across time. This is slightly different from Glaeser’s consumer cities; economic gains, as physiological needs, are always important for population growth. As higher-level needs, social and natural amenities, including Internet accessibility and urban green space, did not affect growth until the turn of the new millennium. In terms of negative factors, the ‘crowding-out effect’ of living costs and environmental pollution are not significant, as theoretically expected, suggesting that residents tend to care more about development opportunities than the negative impacts of living in high-ranking cities. Finally, policies are proposed to promote population growth and the coordinated development of large, medium, and small cities in the Yangtze River Delta.
