中原经济区人口与经济空间格局演变研究

研究中原经济区内部人口与经济的空间关系对促进中部崛起具有重要决策参考意义。基于中原经济区2000～2015年各市和各县人口和GDP数据，运用不均衡指数、地理集中度等方法，从全局和局部两个层面分析中原经济区人口与经济空间关系的动态变化特征。结果表明：①从全局来看，中原经济区人口与经济不均衡指数数值在逐渐增大，表明区域整体人口规模和经济发展规模向不均衡发展，区域内部差异在逐渐增大；②在局部空间上，集中度指数显示中原经济区人口地理集中度呈现出中东高、西部低的分布特征，经济地理集中度呈现出中部高、四周低的分布特征；ESDA分析发现中原经济区人口与经济在空间上趋于集聚分布，且两者空间相关性显著。最后在实证分析的基础上提出政策建议和未来的研究方向。

Study on the Relationship between Population and Economic Spatial Distribution in Central Plains Economic Zone

To study of the spatial relationship between population and economy in the Central Plains Economic Zone has a great decision-making significance to guide sustainable development and promote the rise of this region. Based on the data of resident population and GDP of each city and county (district) in the Central Plains Economic Zone from 2000 to 2015, spatial dynamic characteristics of population and economy in the Central Plains Economic Zone are analyzed by taking unbalanced index, geographical concentration and other methods from both overall and local views. Results show that: ①From a global perspective, the population and economic unbalanced index in the Central Plains Economic Zone gradually increased during the study period, indicating that the overall population size and economic development scale of this region were unevenly developed, and the internal gap of development kept growing; From a local view, the geographical concentration of population in the Central Plains Economic Zone shows a distribution of low in the middle east and high in the west, while the economic geographic concentration shows a distribution of high in the center and low around. And then, a clear understanding that the distribution of population and economy in the Central Plains Economic Zone tends to be agglomerate can be presented by applying the ESDA method, and the correlation between population and economic space is significant. Finally, on the basis of empirical analysis, policy suggestions and future research direction are proposed.
