Xi'an Metropolitan Area Development Strategy Research

Regional economy collectivization, especially the formation of metropolitan circle has already become an important trend in the development of world economy. Every region seeks for optimum scale benefit through regional cooperation characterized by sharing resources and benefits. In this process, metropolitan circle has been growing rapidly and the metropolitan circle pattern has become the leading pattern of economy development. At present, Chang Sanjiao metropolitan circle and Zhu Sanjiao metropolitan circle have been pioneers of China's economy. But comparing with other provinces, Shaan Xi province has a slower pace of development and maybe one of the reasons is that its metropolitan circle has not worked effectively. Thereby, theory of metropolitan circle is employed in this paper to research Xi'an metropolitan circle in accordance with the trend of regional cooperation and to accelerate development of Guan Zhong economical belt.On the basis of metropolitan circle theory, the necessity and possibility for developing Xi'an metropolitan circle is discussed. After measuring its boundary, the development strategy and several corresponding suggestions are proposed. First, correlative concepts of metropolitan circle are analyzed to establish a theory frame. Second, the development patterns at home and abroad are researched, with especial attention to Chang Sanjiao pattern and Zhu Sanjiao pattern, and general rules of metropolitan development are summarized. Third, from the aspects of location condition, traffic condition, industry foundation and existed problems, it is analyzed that the area around Xi'an within 100-kilometer radius. On the basis of this, the possibility for developing Xi'an metropolitan circle is demonstrated. Fourth, fractal theory is applied to demonstrate the feasibility of jointly calculating two core cities, Xi'an and Xian Yang. Potential theory and gravitation model are adopted to measure the economical relationship between Xi'an and Xian Yang and their respective surrounding areas, thus the space boundary of Xi'an metropolitan circle can be confirmed. Finally, development strategy of Xi'an metropolitan circle is proposed including strategic goal, approach to the strategy and rudders, as well as space organization strategy, industry distribution strategy, traffic infrastructure strategy and several corresponding suggestions.
