| 摘 要： | 本研究应用标准差椭圆方法,基于沿海地区113个城市对2003年~2011年沿海地区经济空间差异展开动态研究。结果表明:①沿海地区经济空间差异主要存在于南-北方向,呈明显的减小趋势;②沿海地区经济空间差异波动与区域经济空间格局演化相吻合,沿海地区GDP空间分布明显扩张,人口空间分布略有收缩,二者空间分布重心间的距离减小;③同时期,我国经济空间差异主要存在于东-西方向,具有减小态势,沿海地区经济空间差异与其变化趋势大致相同。建议构建以华北平原、长江中下游平原为核心的经济发展区,有助于促进沿海经济空间由南向北发展;加大对安徽、湖北等靠近全国人口重心的经济投入力度,可以减小全国经济空间差异,促进我国经济的沿海-内陆双轮驱动发展。

| Abstract: | This paper applied the method of standard deviation ellipse to pro ject and visualize the spatial disparity of economy in coastal area of China from 2003 to 2011. The results showed that： ①the spatial disparity in coastal areas is mainly between the southern area and the northern area, and it is with a significant decreasing trend; ②the decreasing trend of the spa tial disparity matches the temporal dynamics of the economic spatial pattern in coastal areas. The spatial range of GDP in coastal areas is obviously expand-ing while that of the population is contracting slightly, and the distance be-tween the spatial gravity center of GDP and that of the population is decreas＆amp;nbsp;ing; ③at the same period, the spatial disparity of the national economy in China is reducing and is mainly between the eastern area and the western area, and the changes of spatial disparity in coastal areas have roughly similar trends.It is recommended to build the economic core area in the region of the North China Plain and the Yangtze River Basin which could promote the economic development in the northern region of the coastal area, and to increase the investment in the provinces of Anhui, Henan and Hubei that are close to the domestic market which could coordinate the coastal economy with the inland to reduce economic disparities in the country. |
