【摘要】：基于标准差椭圆和地理加权回归方法,对2000—2015年我国交通客货流时空演化特征及其与经济发展的空间关联性进行测度。结果表明:(1)受国际国内市场环境的影响,客货流标准差椭圆呈现明显的"东西往返"移动轨迹,核心区持续快速发展一段时间后出现疲软态势,转入中低速常态化发展模式,整体发展趋于均衡。(2)沿海和全国客货流标准差椭圆呈现相近的运动轨迹,呈现空间一体化发展格局。扩大内需、培育人们消费能力成为客货流发展的关键。(3)客货流与经济发展的空间关联呈现明显的空间差异,经济基础发展相对较好的城市凭借周边地区的依附作用,关联度相对较高,而发展相对有限的城市则相反。
[Abstract]:Based on standard deviation ellipse and geographical weighted regression method, the spatial and temporal evolution characteristics of passenger and cargo flows in China from 2000 to 2015 and their spatial correlation with economic development are measured.The results show that under the influence of the international and domestic market environment, the standard deviation ellipse of passenger and cargo flow presents a clear "east-west" movement trajectory, and the core area shows a weak trend after a period of sustained and rapid development, and turns to the medium-low speed normalizing development mode.The overall development tends to be balanced. 2) the ellipse of standard deviation of passenger and cargo flows in coastal and national areas shows similar movement track and presents a pattern of spatial integration.Expanding domestic demand and cultivating people's consumption ability become the key to the development of passenger and cargo flows.) the spatial correlation between passenger and cargo flows and economic development shows obvious spatial differences. Cities with relatively good economic development depend on the dependence of the surrounding areas.The degree of correlation is relatively high, while the city with relatively limited development is the opposite.
