摘要:

以长江沿岸22个主要港口为研究单元,构建综合评价指标体系,运用基尼系数和标准差椭圆方法,分析2004-2014年沿江港口物流发展时空演化特征及其影响机制。结果表明:沿江港口物流发展地带性差异显著,东、中、西部港口群整体发展水平由东向西递减,而发展增速由东向西递增;个体层面上各港口物流综合发展水平也存在较大差距,并表现出明显的规模等级结构特征;沿江港口物流及其三个子系统的发展差异均呈逐步缩小态势,对港口物流整体发展差异贡献由大到小依次为城市支撑、基础设施和物流运营子系统;沿江港口物流发展重心逐步向长江中上游偏移,港口物流发展空间格局趋向分散化。区域经济发展的均衡化趋势、港口集疏运网络的持续优化、港口腹地竞争的多领域发展和港口物流区际合作的深化是沿江港口物流发展格局演化的重要驱动因素。

Abstract:

Port logistics, which is a special form of integrated logistics system, gradually develops through the long-term interactions of natural, social, and economic factors. The strong spatial agglomeration and organizational capacity of port logistics on global supply chain elements (such as material flow, business flow, information flow, and capital flow), makes it a critical factor influencing regional survival, competition, and development. Thus, the formation and evolution of port logistics has become a topic of research interest in the transportation geography sector. Based on the connotation of port logistics, this study takes the major 22 ports along the Yangtze River as the research object and develops a comprehensive evaluation index system of port logistics development. This study then analyzes the spatio-temporal evolution characteristics and mechanism of port logistics development along the Yangtze River, by using the methods of Gini coefficient and standard deviational ellipse. Our study revealed that: (1) The development of the port logistics system along the Yangtze River has significant zonal differences. The overall development level of port logistics of the eastern, central, and western port groups is decreasing from east to west, but the growth rate is increasing from east to west. At the port level, a relatively large gap is observed in the comprehensive development level of port logistics along the Yangtze River due to the geographical environment, hinterland, transportation conditions, as well as other factors. Furthermore, we also found that the hierarchical structure characteristics of the port logistics system are evident. (2) With the constant development of the port logistics industry along the Yangtze River, development differences among the port logistics system and its three subsystems are constantly decreasing. Moreover, the effect sequence of the three subsystems on the comprehensive Gini coefficient of the port logistics system is as follows: city support, infrastructure, and logistics operation subsystem. (3) From 2004 to 2014, the gravity of the port logistics system has significantly transferred toward the upper and middle reaches of the Yangtze River. In addition, the major axes, minor axes, and area of the standard deviational ellipse of the port logistics system continued to grow. This indicates that there is an obvious decentralized tendency in the spatial pattern of port logistics development along the Yangtze River. (4) Lastly, this paper argues that the four main influencing factors of the spatio-temporal evolution of port logistics along the Yangtze River can be attributed to the balanced development of the regional economy, continuous optimization of the transportation network, intense hinterland competition among ports, and constant deepening of the regional port logistics cooperation.
