“一带一路”中国段节点城市竞争力空间分布

The Spatial Distribution of Urban Competitiveness of the Node Cities Along the “one Belt and one Road ”within Chinese Territory

以"一带一路"中国段节点城市为研究单位,建立城市竞争力测度指标体系,借助因子分析法、Arc GIS对28个节点城市的城市竞争力空间分布状况进行定量研究,并对其动力机制进行分析.分析发现:(1)28个"一带一路"中国段节点城市中,综合城市竞争力大体呈现东高西低的分布状况,位于沿海及沿长江黄金水道的城市综合竞争力水平高,呈现弓型分布.(2)经济竞争力与综合城市竞争力空间分布相一致,相关系数为0.826.(3)工业三废的排放量与环境竞争力呈负相关,其平均相关性系数为-0.795,各城市在发展经济的同时,应注重环境治理,进一步提升综合竞争力.(4)基础设施完善的城市综合竞争力较高,其相关性系数为0.639.同时"一带一路"中国段节点城市综合竞争力的空间分布状况会受到区位条件、基础设施完善程度、集聚效应等因素的影响.

In this paper,taking the node cities along the ＂one Belt and one Rode＂within Chinese territory as the research unit,the urban competitiveness evaluation index system is developed. Using the SPSS software factor analysis method and Arc GIS method,the spatial distribution of urban competitiveness of the 28 Node Cities is evaluated and its dynamic mechanism is analyzed at the same time. The results showed that（ 1） 28 nodal cities which are located in the eastern coastal areas possess relatively high comprehensive urban competitiveness.These cities along the coastal areas and golden waterway of the Yangtze River have high comprehensive competitiveness and show bow type distribution.（ 2） The spatial distribution of the economic competitiveness and the urban competitiveness are consistent,the correlation coefficient is 0. 826.（ 3） The emissions of industrial waste is negatively related to environmental competitiveness,and the average correlation coefficient is- 0. 795. In the development of economy,people should pay attention to environmental governance for further enhancing the comprehensive competitiveness.（ 4） The city with perfect infrastructure has a high comprehensive competitiveness and the correlation coefficient is 0. 639. At the same time,the spatial distribution of the urban competitiveness of the node cities along the ＂ one Belt and one Road＂within chinese territory are influenced by the factors of location condition,the degree of the improvement of the infrastructure,the concentration effects and so on.
