中国基础设施与城乡一体化的关联发展

运用灰色关联分析法,构建了基础设施与城乡一体化关联度模型,进行区域尺度两者的二级指标关联度、标准关联度和动态关联系数的计算,实现了对区域基础设施与城乡一体化关联水平的定量分析。研究结果表明：20年来,中国区域基础设施与城乡一体化发展的关联水平存在着明显的东、中、西空间差异,并随着不同时期区域政策的变化而有所波动。自20世纪70年代末至90年代初,东、中、西梯度差异比较明显,90年代中期这种格局被打破,到2000年出现了更高层面上的东、中、西明显分异。最后,基于不同省区的基础设施与城乡一体化动态关联系数,将全国分为上升型、下降型、U型和小幅波动型四种演化类型,并进行了类型成因分析。

Assessment and Empirical Study on the Relationship between Infrastructure Construction and Urban-Rural Development

Urban-rural development has always been illustrated as the interdependent and interaction relationship, represented by the free flow of population, commodities, capital and information between urban and rural areas, which, in some sense, guarantees the effective and efficient uses of resources in urban and rural areas. It is self-evident that the construction of regional infrastructure is a precondition for regional urbanization.The improvement of public infrastructure shortens the "spatial distance" between urban and rural areas, widens the built-up areas, pushes outside the urban fringe and forms, in some time, a new form of spatial complexity in which urban and rural areas are intensely mixed or "interlocked". The joint development of urban and rural areas depends on the increase of capital investment for infrastructures mainly cover transportation, telecommunication, education, medical facilities and welfare. We can safely come to a conclusion that regional infrastructure is indispensable to the development of urban and rural areas and lays the foundation for the relationship generation between regional infrastructure and urban-rural development. On the other hand, the strong interaction between urban and rural areas will promote the construction and improvement of regional infrastructure. Many scholars have paid much attention to the relationship between regional infrastructure and urban-rural development now. It has important implications for the construction of infrastructure and improvement of social and economic benefits to find out and assess the relationship between regional infrastructure and urban-rural development.
