中国全国与沿海地区经济空间一体化趋势

On the Trend of Integration of Economic Space in China and its Coastal Area

利用空间统计方法精细地刻画了2003—2011年我国全国及东部沿海地区GDP和消费市场的空间变化。2003年以来,我国GDP及消费市场空间向内陆方向移动,呈现收缩密集化态势,表明国内市场对我国经济的驱动作用在增大,国内市场一体化程度在提高;同时,沿海地区GDP与消费市场空间呈现快速密集化趋势,GDP空间向内陆移动、收缩,消费市场空间向南移动、扩张,表明聚集经济对沿海地区的驱动作用明显高于它对全国的影响,沿海地区在引领全国经济一体化进程,国际市场对沿海地区的驱动作用高于它对全国的影响。在我国经济转型的关键时期,要充分发挥国内市场一体化的驱动作用,构建以华北平原和长江中下游平原为依托的国家经济核心区,推动我国经济向沿海—内陆共同发展转型。

This paper uses standard deviation ellipse to identify the spatial evolution of GDP and consumer market in China and its coastal area during 2003 and 2011. It is showed that GDP and consumer market in the country move toward inland and become spatially contracted and intensified, indicating a rising role of domestic market and increasing market integration. Meanwhile,in the coast area, the extent of spatial intensity of GDP and consumer market increase faster than in the whole country. While GDP moves toward inland, and consumer market moves to south and shrink spatially, suggesting a stronger role played by agglomeration economies in the coast area than in the country. The rising market integration is driven by the coast area, and a larger impact is exerted by global market in the coast area than in the country. For a smooth and fast transformation, the role of market integration should be addressed, the economic core should be established over the North China Plain and Middle - Lower Yangtze Plain, and national growth should be driven both by the coast area and the interior as a whole.
