基于引力模型的宁夏沿黄经济区城市间联系测度研究

A Gravity-Mode-based Contact Measurement Research of Cities in Economic Zone Along the Yellow River

通过应用引力模型对沿黄经济区内城市中心等级的划分、可达性的分析、经济联系度的测算,总结出了沿黄经济区发展的三个问题,即:1中心城市的质量太小,辐射带动作用较弱;2城市数量太少,辖区范围太小;3整体经济发展水平落后,各城市之间的联系度较小。在此基础上为沿黄经济区的发展提出了若干建议:1统一规划、合理布局;2加大对银川市这一增长极的培育,增强其区域核心地位;3加强区域内城市之间的联系,提高经济区的整体竞争力;4加快区域内城市一体化的建设。

Through hierarchical division of city centers in Economic Zone Along the Yellow River, accessibility analysis, economic contact measurement that are based on gravity model, three problems about the development of Economic Zone Along the Yellow River is summarized, namely： （1） low city center quality and weak radiating and leading effect; （2） few city number and small jurisdiction scope. （3） backward overall economic development level and loose city-city connection. On this basis come some Suggestions for the development of the Economic Zone Along the Yellow River： （1） unifying planning and rationalizing layout, （2） reinforcing the nurturing of yinchuan＇s growth pole and heightening its role as the core area; O） strengthening connections between cities in the area and improving the overall comvetitiveness of the economic zone. （4） accelerating the construction of urban integration in the area.
