[目的]研究区域经济格局对揭示经济发展空间演变机制和实现区域可持续发展具有重要的意义。文章以粮食生产核心区——河南省为例,通过定量刻画其济格局时空分异特征,明确河南省经济格局的发展态势和演化特征,为河南省经济发展提供参考。[方法]文章采用GIS空间分析和AHP方法,通过建立经济评价指标体系,基于2010—2015年河南省的统计年鉴数据评价其经济格局分异特征。[结果](1)总体上,河南省国民生产总值持续增长,经济发展持续向好,但经济增速逐年放缓。(2)河南省经济空间格局先后经历了“八”字形、“一”字形演变特征,并逐步形成以郑州为中心的“十”字形经济空间格局。(3)全省中高经济发展水平城市数量增多,各地市经济发展的差异逐步缩小。[结论]河南省经济内部差异呈下降趋势,全域经济带动效益开始显现,应强化城市辐射效应,并加强对更小尺度经济格局演变的研究。 |

Abstract: |
The study of regional economic patterns is of great significance for revealing the spatial evolution mechanism of economic development and realizing regional sustainable development. Taking the core area of food production Henan province as an example, this paper clarifies the developmental situation and evolution characteristics of Henan′s economic pattern by quantitatively depicting the spatial and temporal differentiation characteristics of its economic structure, which provides references for Henan′s economic development. This research used GIS spatial analysis, AHP method and cluster analysis method to establish the economic evaluation index system. Meanwhile, it revealed the differentiation characteristics of Henan′s economic pattern based on the Statistical Yearbook Data of 2010 2015 in Henan province. The results showed that: (1)The GNP was a continuous growing in Henan province, economic development continued to improve, but the economic growth rate slowed down year by year; (2) The economic pattern had undergone the evolution characteristics of the "eight" and "one" shapes, and gradually formed the "ten" shaped economic spatial pattern centered on Zhengzhou;(3)The number of cities with high and medium levels of economic development in the province had increased, and the differences in the economic development among cities and regions had gradually reduced. In summary, the internal economic differences in Henan province showed a downward trend, and the benefits of the global economy began to appear. The urban radiation effect should be strengthened and the research on the evolution of smaller scale economic patterns should be strengthened. |
