山东省公路货运流与区域经济关联特性研究

Research on the Correlation between Road Freight Flow and Regional Economy in Shandong Province

为科学分析区域物流与经济空间格局,运用公路货运数据研究区域物流与经济的关联特性,通过集聚度和修正后的联系强度模型等方法分析山东省61个地级市的物流与经济空间集聚程度,利用改进的引力模型分析公路物流与经济的空间关联性。结果表明:1) 物流集聚和经济集聚在空间上存在正相关性,在一定程度上会协调促进,互为因果;2) 物流与经济集聚度高的城市对物流与经济集聚度低的城市的物流发展在空间上存在剥夺效应,而对物流与经济联系较高的区域具有带动作用;3) 山东省城市物流与经济的一般联系、弱联系在空间分布上总体存在不均衡性,物流联系不均衡现象较为显著,地理、政策、历史等主客观因素对城市间物流联系的阻碍作用高于对城市间经济联系的阻碍作用。

In order to scientifically analyze the spatial pattern of regional logistics and economy, the correlation characteristics of regional logistics and economy are studied by using road freight data, the spatial agglomeration degree of logistics and economy in 16 prefecture-level cities in Shandong Province is analyzed by means of agglomeration degree and modified connection strength model, and the spatial correlation between road logistics and economy is analyzed by using the improved gravitational model. The results show that: 1) there is a positive correlation between logistics agglomeration and economic agglomeration in space, which will be coordinated and promoted to a certain extent, and are mutually causal;2) cities with high logistics and economic agglomeration have spatially depriving effects on the logistics development of cities with low logistics and economic agglomeration, but have a driving effect on areas with high logistics and economic ties;3) the general and weak links between urban logistics and economy in Shandong Province are generally unbalanced in spatial distribution, and the imbalance of logistics connections is more significant, and the hindering effect of subjective and objective factors such as geography, policy, and history on logistics connections between cities is higher than that on economic links between cities.
