Derived Data

Against the background that urbanization has proceeded quickly in China over the last two decades, a limited number of empirical researches have been performed for analyzing the measurement and driving forces of urban sprawl at the national and regional level. The article aims at using remote sensing derived data and administrative data (for statistical purposes) to investigate the development status of urban sprawl together with its driving forces. Compared with existing studies, NPP/VIIRS data and LandScan data were used here to examine urban sprawl from two different perspectives: urban population sprawl and urban land sprawl. Furthermore, we used population density as a counter-indicator of urban sprawl, and the regression results also prove the superiority of the urban sprawl designed by us. The main results show that the intensity of urban population sprawl and urban land sprawl has been enhanced. However, the upside-down between the inflow of migrants and the supply of urban construction land among different regions aggravates the intensity of urban sprawl. According to the regression analyses, the driving mechanism of urban sprawl in the eastern region relying on land finance and financial development has lost momentum for the limitation of urban construction land supply. The continuous outflow of population and loosely land supply have accelerated the intensity of urban land sprawl in the central and western regions. The findings of the article may help people to realize that urban sprawl has become a staggering reality among Chinese cities; thereby urban planners as well as policymakers should make some actions to hinder the urban sprawl.

The supply of construction land index is difficult in coal villages migration, especially the construction land index in urban and rural, lacking of construction land index becomes the bottleneck of village migration. In order to ruduce the pressure of the contradiction between supply and demand of land used for construction purposes. This paper combines with the actual situation of coal villages, taking Huainan as an example, starting from the connotation and significance of the policy of linking the increase in land used for urban construction with the decrease in land used for rural construction, based on the analysis of the current situation of the city construction land use, making predictions on the potentiality of village land readjustment in coal mining areas, the potentiality of the rural residential areas hook readjustment and the potentiality of linking the increase in land used for urban construction with the decrease in land used for rural construction, the results show that the overall hook potentiality is larger.

Land Supply And Demand

Considering the increasingly tense relationship between construction land supply and demand, we study the inherent rules and the spatial evolution in construction land use. In order to solve the problem of parameter optimization effectively, we analysis the fundamental theory of Support Vector Machine and finally accomplish the combination of genetic algorithm and support vector machine. Meanwhile we apply this model to analysis the construction land use and propose a new model, which is based on the support vector machines with genetic algorithm, for construction land evolution. Taking Guandu district in Kunming, Yunnan as a case, we find out that the new model is far superior to recent models in terms of predicting accuracy, algorithm complexity and computational efficiency. And therefore, we believe that this is highly precise, practical and efficient model for forecasting construction land use and evolution.

In this paper, the author compared the changes of urban construction land and driving forces in Jing-Jin-Ji urban agglomeration, Yangtze River Delta urban agglomeration and Peal River Delta urban agglomeration from 2000 to 2008, which was in order to find out the differences in changes laws and influential factors. The author introduced Correlation analysis, Co-integrated relationship and Granger causality test in metrology analyses to further research the relationship between urban construction land changes and driving forces.

State Functions

Encountering the articulation of the strongness of local authorities and market forces in China’s development, attention has been paid to the changing central state which recentralised the regulation capability of localities which has more discretional power on resources utilisation, land for example, in the post-reform era. Yet it is still not clear-cut what drives the state rescaling in terms of land governance and by what ways. After dissecting the evolving policies and practices of construction land supply in China with the focus on the roles of state, we draw two main conclusions. First, the policy trajectory of construction land supply entails a complicated reconfiguration of state functions, which is driven by three interwoven relations: land–capital relation, peasant–state relation and rural–urban relation. Second, state rescaling in terms of the governance of construction land provision works via four important approaches: limited decentralism, horizontal integralism, local experimentalism and political mobilisationism. By reviewing the institutional arrangements of construction land provision and the state rescaling process behind them, this article offers a nuanced perspective to the state (re)building that goes beyond the simplified (vertical or horizontal) transition of state functions.
