The development framework and mechanism of Xi''an city''s regional spatial structure
西安城市地域空间结构发展框架和发展机制

Through the analysis of the disadvantageous factors in regional spatial development of Xi'an city, the authors put forward the main urban development framework for New Xi'an,i.e., "One core and three inferior cores"pattern which provides new regional space of urban development. This can form a reasonable layout and orderly development. The clustering city structure should be formed, which can take effective measures to protect cultural relics and ruins and can emphasize ecological construction. Xi'an city's development mechanism is discussed from different angles such as the relationships among cities, Guanzhong urban belt, and the northern part of central and west regions of China. Then the author suggeststhat the goal of urban development should be redefined according to the principlesof integrated planning, colligated allocation, division of labor and co-operation for the harmonization of coordinated development, tourism economy, urban construction and environmental protection.Taking tourism and trade, scientific research and education and high-tech industry as dominant factors and the internationalization of urban running mechanism, running modes, and running environment as criterion, the internationalization of urban comprehensive function can be promoted and the goal of leaping over development can be eventually realized.
