“…As mentioned above, in 2014, the level of urbanization in China was about 55%. According to Shi et al (2016) [31], China is now in the accelerating stage of urbanization, and when the proportion of urban population accounts for about seventy percent of the total population, the growth trend of urban population will be slowed or even stagnated; then, the demand for urban land will also be stable. Therefore, when the level of urbanization tends to be stable, the current land finance model based on the expansion of urban land in China will also be difficult to continue.…”

Abstract:Land finance, i.e., a city government's revenue, depends deeply on the revenue from transferring multiannual land use rights and is a phenomenon unique to China. However, due to increasingly tense land supply, increasingly prominent social conflicts, and the slowdown of urbanization in China, the country is entering what we may label the "post-land finance" era. Therefore, revenue from land finance is decreasing, which threatens the sustainability of Chinese city governments' debt, especially in major cities. This paper tests the long-term sustainability of major Chinese city governments' debt. Different from intuition, the empirical results show that the debt of these major city governments is still sustainable at the macro level. This paper also constructs a quadratic function model to predict the critical value of the local government debt. Our results suggest that despite the fact that debt is still sustainable, critical value may be reached quickly, as debt is growing rapidly. There is thus a need for local fiscal reform that divides financial power and authority between the local governments and the central government more reasonable and clearly, improves the current assessment mechanism of local governments' officials, and speeds up the legislative work on property taxes.

“…With the unprecedented rate of metropolitan growth, there is an increasing demands and competitions for the limited available land, which requires government agencies to devise effective and sustainable plans of land use. Besides, the metropolitan growth can lead to several ongoing and emerging challenges, such as environmental pollution [9], agricultural land loss [10], biodiversity degradation [11,12], and lack of infrastructure [13]. How to tackle these problems also needs the knowledge of growth patterns for a better planning and policy making on sustainable development.…”

Characterizing the Growth Patterns of 45 Major Metropolitans in Mainland China Using DMSP/OLS Data

Abstract:Understanding growth patterns at the metropolitan level is instructive for better planning and policy making on sustainable urban development. Using DMSP/OLS data from 1992 to 2013, this article aims to investigate growth patterns of major metropolitans in Mainland China from the aspects of intensification and expansion. We start by calibrating the DMSP/OLS data and selecting 45 major metropolitans. On intensification, results suggest that aggregately, metropolitans displayed cyclical pattern over time and large metropolitans tended to have higher levels of intensification than moderate or small ones. Individually, metropolitans with similar intensification over time could be clustered together using Dendrogram, and evolution pattern of the clusters exhibited similarity to the aggregated one. On expansion, results show that aggregately metropolitans displayed a decreasing trend over time, and moderate or small metropolitans tended to have higher levels of expansion than large ones. Particularly, moderate metropolitans were more likely to expand adjacently, and small ones were more likely to experience scatter or corridor expansion. Each metropolitan can be represented by a mixed expansion model over time, which might tell where and how much expansion occurred in the current year. Furthermore, intensification is highly correlated with expansion over time for small metropolitans, but they are poorly correlated for large or moderate ones. Lastly, the high correlation of intensification and expansion with the change of GDP in each year indicates the reliability of our work.

“…As one aspect of urbanization, land use change, especially urban land expansion was proven to cause cropland loss (r=−0.97, p<0.01 in the Bohai MUR, figures 2 and 7) (Shi et al 2016, Ju et al 2018. Similarly, rapid urban area expansion has led to the loss of some highly productive croplands worldwide, especially in MURs in Asia and Africa (Bren d'Amour et al 2017).…”

The security of food-energy-water (FEW) systems is an issue of global concern, especially in megaurban regions (MURs) with high-density populations, industries and carbon emissions. To better understand the hidden links between urbanization and FEW systems, the pressure on FEW systems was quantified in a typical rapidly urbanizing region-the Bohai MUR. The correlations between urbanization indicators and the pressure on FEW systems were analyzed and the mechanism of the impact of urbanization on FEW systems was further investigated. The results showed that approximately 23% of cropland was lost, 61% of which was lost via conversion to construction land and urban areas expanded by 132.2% in the Bohai MUR during 1980-2015. The pressure on FEW systems showed an upward trend, with the stress index of the pressure on FEW systems (FEW_SI) ranging from 80.49% to 134.82%. The dominant pressure consisting of that has converted from water system pressure to energy system pressure since 2004. The FEW_SI in the Bohai MUR was enhanced with cropland loss and increases in urbanization indicators. Additionally, land use, populations, incomes, policies and innovation are the main ways that urbanization affects FEW systems in MURs. This study enhances our understanding of the variation in pressure on FEW systems in MURs and the effects of urbanization on FEW systems, which will help stakeholders to enhance the resilience of FEW systems and promote sustainable regional development.
