Compact City is an urban planning and development concept which promotes relatively high population density associated with an integrated and mixed-use land district. It is enabled by transit-oriented development and results in low transport-related energy consumption and reduced the GHG （Greenhouse Gases） pollution. Compact City conserves the natural capital of land mass and subscribes to the strong sustainability ethics. ICT （Information and Communications Technology） could be deployed to optimize the Compact City operations by first tackling some of the development problems associated with Compact City and also unleashing new urban innovations and functionalities to achieve sustainable urbanization. The paper suggests and elucidates several general systemic synergies archetypes such as co-benefits, cascading, ICT infrastructure reuse, etc., which could be leveraged to facilitate the emergence of compact green smart and resilient city. These archetypes are solutions to the Compact City paradigm thus conductive to the development ofa Sustainability Science of Compact City.展开更多

The role of these new centres in transforming the inner cities of some of the UK＇s larger conurbations is examined and the key planning issues are discussed. The article concludes that the key principles of urban planning and control must still apply in shaping the role these new developments have in the UK＇s evolving urban landscape.展开更多

The past urban economics studies have shown that land value is largely determined by location factors such as distance from Central Business District （CBD） ignoring the non-location factors like time of purchase and neighbourhood infrastructures. Therefore, this paper attempts to establish the relative importance of location and non-location factors in the determination of residential land value by positing Onitsha, Nigeria as a case study. Eight hundred and fifty residential housing units were selected and questionnaire administered to the landlords through multi-stage sampling technique. The stepwise regression analysis results showed that non-location factors, especially, time of land purchase, contribute more to the variation in residential land values. The paper suggests the revision of the classical economic theories to represent the conditions of urban areas in developing countries .展开更多

However because the resource is of exhausting character, this means that the region has hidden troubles of economic depression. The paper analyzes the formation of resourceful region and the law of resourceful regions economic development, and then the paper brings forward that the resourceful region has a potential danger of economic depression. Considering Chinas economic development practice, the paper puts forward a basic way of thinking. That is: we must attach importance to the problem of industrial structure when we pay attention to existing resource advantage in order to avoid the simplification of regional industrial structure and to avoid entering a vicious cycle.展开更多
