中文摘要:
      为优化海上丝绸之路的海运枢纽网络,推行“一带一路(B&R)”的倡议,在传统轴辐式海运网络的基础上分别建立线型、环型枢纽网络结构,并引入规模效应折扣,用遗传算法求解不同海运网络的枢纽选址问题.最后,根据结果对3种不同的网络结构即轴辐式网络和线型、环型枢纽网络的适用性和总成本进行比较分析.结果表明:在“一带一路”倡议提出的背景下,改变单分配轴辐式网络结构,构造线型、环型枢纽网络,能够充分发挥政策引导的规模效应,从而降低总运输成本.进一步证明“一带一路”倡议对于沿线地区发展海运贸易具有积极作用.
英文摘要:
      In order to optimize the maritime hub network of the Maritime Silk Road and promote the implementation of the Belt and Road Initiatives (B&R), based on the traditional hub-spoke maritime network, the structures of the linear and circular hub networks are established separately. With introducing the discount of scale effect, genetic algorithm is used to solve the hub location of different maritime networks. Finally, based on the results, the applicability and total costs of three different network structures, i.e., hub-spoke network, linear hub network and circular hub network, are compared and analyzed. The results show that under the background of the Belt and Road Initiatives, changing the single allocation hub-spoke network and constructing the linear and circular hub network can give full play to the scale effect of policy guidance and reduce total transportation costs. It further proves that the Belt and Road Initiatives have positive effect for the development of maritime trade along the region.
