物流通道的形成对沿线区域空间经济联系范围的影响——以中国沿海和长江物流通道为例

Impact on Association Scope of Regional Spatial Economies along Logistics Channel after Its Formation:Take Logistics Channels along Chinese Coastlines and Yangtze River as Example

首先将量化的物流通道技术水平指标引入引力模型,考察物流通道对沿线区域空间经济联系范围产生的影响,再利用ArcGIS10.2的图形处理功能以可视化的方式、从空间视角展示物流通道影响下不同时期的空间经济联系范围变化。研究结果表明:①从时间趋势看,沿海与长江物流通道内不同区域中心城市对外经济联系范围变化不大,表明在物流通道的支持下区域内保持了稳定的经济联系,随着物流通道技术水平的提高,其联系范围越远。②从空间维度看,沿海与长江物流通道影响下区域空间联系范围具有距离越近联系越紧密的一般规律,同时物流通道的形成也使沿线区域中心城市突破了空间距离限制,使区域空间经济联系范围可达300km以上乃至1000km。因此,建设和完善基本构成要素、形成综合物流服务水平高的物流通道对沿线区域经济流通起着重要的作用。

Firstly, this paper introduced the quantified index of the technical level of the logistics channel into the gravity model to investigate the impact of the logistics channel on the association scope of the spatial economies of the regions along the channel. It used the ArcGIS10.2 to display the changes of the association scope of the spatial economies under the influence of the logistics channel over time visually and from a spatial perspective. The result showed that judging by the trend over time, there is little change in the association scope of the regional center cities along the coastal and Yangtze River logistics channels with outside economies, indicating that with the support of the logistics channels, the regions have sustained stable economic associations, and with the technical improvement of the logistics channels, the association scope would further extend;and from a spatial perspective, under the influence of the coastal and Yangtze river logistics channels, the association scope of the regional spatial economies follows the universal law that the closer the distance is, the tighter the connection will be, however, at the same time, the formation of the logistics channels also enables the regional central cities along the logistics channels to break the limit of space and distance, extending the association scope of the regional spatial economies to over 300km or even 1,000km.
