The Economic Efficiency of Urban Land Use with a Sequential Slack-Based Model in Korea

Abstract

Abstract:Since the inauguration of the government-led five year economic plans in the 1960s, Korea has achieved remarkable economic development. Korea's economic strategy, known as 'The Miracle on the Han River', focused on heavy and chemical industries such as ship building and petrochemicals and was based on resource intensive urbanization. This rapid urban development caused a series of problems, such as over-development in urban areas, bottlenecks in utilities, and environmental degradation. Nevertheless, the Korean government has recently moved toward deregulation of the greenbelts of major city areas. Since very few studies have analyzed the urban land use economic efficiency (ULUEE) in Korea, this paper assesses the feasibility of recent deregulation policy concerning the greenbelts utilizing the sequential slack-based measure (SSBM) model under environmental constraints across 16 South Korean cities from 2006 to 2013. Our research makes three significant contributions to urbanization research. First, this paper uses an SSBM model to analyze the dynamic changes of urban land use economic efficiency in Korea at the regional level; Second, this paper analyzes factors influencing ULUEE in Korea, and the feasibility of the deregulation policies on the greenbelts; Third, this paper suggests more performance-oriented policy alternatives to improve the ULUEE and implement sustainable greenbelt management.

Applying SBM-GPA Model to Explore Urban Land Use Efficiency Considering Ecological Development in China

“…Research methods are also increasingly diversified, mainly including the coupling degree model [24], the Cobb-Douglas production function [25], data envelopment analysis [26], stochastic frontier analysis [27], the directional distance function [28], Theil index [29], Gini coefficient [19], and so on (Table 1). The technological framework has evolved from a single indicator framework reflecting the economic benefits of urban land use [30] to a multi-indicator framework reflecting economic, social and ecological development [31]. The research scale includes the country level [18,32], economic belts [33,34], urban agglomerations [35], and typical cities [22,36].…”

Multidimensional Evaluation of Urban Land-Use Efficiency and Innovation Capability Analysis: A Case Study in the Pearl River Delta Region, China

“…According to the China City Statistical Yearbook, China's urbanization rate increased from 36.2% in 2000 to 63.9% in 2020, exhibiting strong growth potential [4,5]. However, with the continuous acceleration of China's industrialization and urbanization process, the rapid expansion of construction land has resulted in the rough use and inefficient idling of urban land, resulting in corresponding socioeconomic and environmental problems, which seriously affect and constrain the sustainable development of regional socioeconomics [6][7][8][9][10]. Currently, China's economy has shifted from highgrowth to high-quality development, and the traditional development model based on land expansion is no longer sustainable; these factors make the conflict between land resource use and economic growth increasingly prominent [11][12][13].…”

Regional differences and dynamic evolution of urban land green use efficiency within the Yangtze river economic belt, China

“…For example, the excessive expansion and extensive use of urban construction land occupied a large number of agricultural lands, resulting in the increasingly acute contradiction between people and land (Cartier, 2001;Lambin and Meyfroidt, 2010;Zhang et al, 2022). Problems such as extensive use of urban land, circle instead of use, and insufficient degree of intensification had led to irrational land use structure and inefficient utilization (La Rosa et al, 2014;Choi and Wang, 2017;. In addition, due to the excessive emphasis on economic benefits of urban land use, a large number of pollution emissions had been generated, resulting in the destruction of ecosystems and endangering the sustainable development of cities (Martínez-Zarzoso and Maruotti, 2011;Chen, 2015;Verma and Raghubanshi, 2018).…”
