The Driving Mechanism of Urban Land Expansion from 2005 to 2018: The Case of Yangzhou, China

Abstract

The driving mechanism of expansion is the basis for policymaking in urban land management and control. In this study, Yangzhou city in China was used as an example. Based on the supply and demand theory of land, a framework was constructed to analyze the driving factors behind urban land expansion. Path analysis was used to determine the direct and indirect factors driving urban land expansion. The results showed the following: (1) Urban land in Yangzhou city expanded 32,831.10 hm2 from 2005 to 2018, mainly in terms of farmland. This rapid expansion arose from the contraction of rural residential areas, threatening ecological spaces such as water bodies. (2) Path analysis indicated that fixed-asset investment, the added value of secondary and tertiary industries, urban population, distance to the city center, and farmland area are the direct factors driving urban land expansion. Land finance, technology input, and transportation ability indirectly influence urban land by affecting other driving factors. (3) Increasing the level of urban land-use intensification, properly adjusting economic development goals, reasonably controlling the population, exploring the retention of construction land in city centers, and optimizing farmland and basic farmland plans need to be considered in the management and control of urban land expansion. Furthermore, to guide the orderly expansion of urban land, improving land management systems, promoting scientific and technological progress, and scientifically designing transportation land are necessary strategies.

Analysis of changes in the spatiotemporal characteristics of impervious surfaces and their influencing factors in the Central Plains Urban Agglomeration of China from 2000 to 2018

“…The urbanization rate indicator used in this paper refers to population urbanization, which is an important indicator reflecting the urbanization process, and the population factor is an important influencing factor driving urban land expansion [ 39 , 40 ]; i.e., population growth is a direct driver of urban expansion. As the population grows, the demands for housing, education, and healthcare increase, bringing with them the constant expansion of cities and an increase in ISA size.…”

Spatial Rearrangement of Manufacturing Industrial Zones Based on MCDM in Mojokerto Regency. Case Study Northern Mojokerto Region

“…These two phenomena are interconnected; on one hand, urban land use expansion can lead to an increase in industrial land use. Conversely, agglomeration and industrial growth can drive urban land use expansion [2]. Industrial activities play a crucial role for conditioning urban innovation and development in shaping the city's form and act as the prime mover of urban growth [3].…”

Pro-Environmental Behavior: Examining the Role of Ecological Value Cognition, Environmental Attitude, and Place Attachment among Rural Farmers in China

“…1 in China points out that it is important to control non-point pollution in agriculture. However, due to the dispersibility and crypticity of internal pollution, as well as the deficiency of labor and funding, “government failures” still exist in rural environmental management [ 7 , 8 ]. New institutional economics consider that induced institutional changes are more effective than imposed institutional changes [ 9 ].…”
