郑州市经济空间结构演变及其经济溢出效应

The evolution of spatial economic structure and its spillover effects on regional economic growth in Zhengzhou

基于小尺度视角,计算郑州市2000,2005,2010年的人均GDP指数,分析郑州市经济空间结构时空演变的规律;建立空间自相关模型分析郑州市经济溢出效应。研究结果表明,2000—2010年郑州经济整体呈现集聚趋势,形成明显的带状;郑州辖区、市、县的经济增长空间相关性不显著,经济发达和次发达辖区、市、县对周边的影响较大,表现出集聚效应,经济欠发达和落后辖区、市、县对周边几乎没有影响,没有表现出溢出效应。

This paper examines the evolution of spatial economic pattern Zhengzhou city by using district as a spatial unit and per capita GDP of Zhengzhou in 2000,2005 and 2010 as measuring index for the level of regional economic development. The result shows that the economy in Zhengzhou appears in a process of spatial centralization and the spatial economic structure supports notion of core periphery suggested by regional economists. The effects of these patterns on economic growth shows that in Zhengzhou as a whole there is no prominent spatial correlation of economic growth between one district and its neighborhood districts. In other words, there is no evidence supporting the spillover effects of e- conomic growth between one district and its neighborhood districts. But within the agglomeration region of the city, the spillover effects of economic growth between districts are apparent.
