There is a principle-agent relationship between central government and all levels local governments on land protection. The local government is the administrator, demander and the only supplier for the local land market. The problems in the land protection such as externalities, asymmetric information, over-long agent chain and the shortage of effective incentive systems lead to the behavior deviation of the local government, and also promote the gaming between the local government and the central government for the maximum profits of the local citizen, officials and local governments, therefore, result in the nonstandard land market of China and unreasonable land use. Principally, such deviation could be attributed to the institutional environment of the local government’s behaviors and the officers’ attitude toward politics. With the application of the government behavior theory, game theory and statistical method, this paper analyzes the behavior logics and institutional factors that result in the deficiency of the land protection of the local government, basing on the characteristics, the motivation and land management systems of Chinese local governments. Furthermore, approaches and measures for adjustment such as property order of the land, management system, and profits share system and the index for political achievement assessment is provided for policy-makers.

Scenario Prediction and Analysis of Urban Growth Using SLEUTH Model

Scenario prediction was introduced to better understand urban dynamics and to support urban planning. Taking the Dongguan central urban area of the Pearl River Delta, China as an example, three urban development scenarios, historical trend (HT) scenario, forest protection (FP) scenario, and growth restriction (GR) scenario, were designed and transplanted into the SLEUTH model through the parameter self-modification method. The quantitative analysis results showed that the urban area would expand continuously from 2003 to 2030 under the HT scenario. More land resources would be saved under the GR scenario than FP scenario. Furthermore, the urban growth under the HT and FP scenarios would come to a steady state by 2020, while this deadline of the GR scenario would be postponed to 2025. The spatial pattern analysis using five spatial metrics, class area, number of patches, largest patch index, edge density, and contagion index, showed that under all the scenarios, the urban patches would become bigger and the form would become more compact, and the urban form under the GR scenario would be the smallest and most heterogeneous. These demonstrated that the GR scenario was more effective in meeting the goal of land protection and sustainable development for the study area.
