Urban fringes are an important part of urban growth. In addition to formal land markets, a variety of informal land development methods make urban fringes the most dynamic and complicated areas. The analysis of land transfer and development systems in these areas opens a significant window to understanding the modern processes of urbanization and human and property rights in urban areas in China. This study uses Shanghai as a case study target and identifies specific modes of local land development and investigates how collective participants, government agencies, regulatory policies, and various actors are involved in land development and decision making. The in-depth analysis and case studies indicate that the variety of informal land markets in Shanghai reflects the inherent demands of the market for allocation of land resources within the constraints of the given system and against the given development background. However, conflicts between the mode of the market and the existing institutional constraints reflect the uncoordinated development of the land and the economic and social development around the urban fringe. The empirical results of this paper suggest that government administration should improve the land market system, strengthen the planning of control and guidance, rationalize the distribution of interests in land development, and strengthen the supervision of management of land development enterprises. Instead of fragmented aspects, this paper proposes a systematic analytical approach to understanding the informal land development in a city from an urban planning and land resource management perspective.

This study presents an agent-based model that simulates the tourist flow diffusion process of a tourism destination system. The model begins by building simple tourist agents, whose main activities are selecting tourist spots and organizing tourism schedules given their unique financial and time constraints. Next, the model utilizes tourist spot manager agents, whose responsibilities are alerting tourists about crowdedness and/or posting advertisements to attract tourists. A regional tourist flow model was developed to simulate the decisions and behaviors of these agents and predict tourist flow direction and distribution. The model was applied to the Sichuan province in China, which has 41 Class 3A and above tourism spots. Under different decision-making scenarios, the results of the model simulations showed that northwest, northeast, southeast, and southwest are the four main tourist flow directions and that crowd-alert would assist in effectively regulating tourist flow and tourism distribution patterns except when long-distance tourists dominate.

Land use efficiency is one of the critical indicators of sustainable development. Increasing land use efficiency can help build a more compact urban form and reduce the urban footprint. Industrial development is often considered a major driving force of urban land use expansion and use change. Both industrial development and urban land use change are constrained and facilitated by urban planning and management, constantly shaping the spatial trajectory of urban transformation. Taking the suburbanization and revitalization of industrial land uses in Shanghai as a case study, this research uses thematical analysis and geospatial data change detection methods to investigate how the evolution of industrial spatial structure leads to urban land use growth, and how urban planning and governance reconfigure the industrial spatial structure of a city through revitalization. This study found that the unplanned suburbanization of industrial land use brought about significant residential and commercial land use expansion. The city was able to consolidate its industrial land uses by adopting the designated industrial blocks strategy to curb the sprawl of industrial land use and enhance land use efficiency. With the transformation of industry structure, the city achieved great success in transforming underutilized industrial land in the city’s central area and consolidating scattered industrial land into industrial blocks in the city’s suburban areas.
