摘要:: 为研究海运通道与其沿海经济区域发展的相互作用关系和演化趋势，在交通经济带理论中拓展海运部分，以海运通道运输量和经济带陆向纵深为共生规模变量，建立海运交通经济带单方非独立共生演化的Logistic模型，以运输经济、烟羽模型、微积分等方法提出其变量作用系数的量化途径和形式，解决未知参数，实现交通运输和地理空间不同范畴、无法直接关联的量的量化联系，并得到作用系数的增长因素和减少因素。研究表明两规模变量的作用系数都随其值增长而减小。由近似线性法，系统演化的非零平衡点存在，并得到对演化平衡点稳定性有纯负面影响的因素，这些因素较大时经济带系统在平衡状态更容易发生相变，适当的海运通道长度有利于保持其经济带的稳定发展。

Abstract:: To study the development interaction and evolutionary trend of shipping passage and its coastal economic area，the part of maritime transportation is expanded in the theory of transportation economic belt.Taking the shipping volume of the shipping passage and the landward depth of the economic belt as the symbiotic scale variables，a unilateral non independent symbiosis evolution Logistic equation of maritime transport economic belt is estabished.This article proposes a quantitative approach and forms of the interaction coefficients of the variables with theories of transportation economy，plume model，and calculus etc.，solving the unknown coefficients，and realizing the quantitative connection between different categories of transportation and geographical space that cannot be directly related，then obtaining the increasing and decreasing factors of the interaction coefficients.Results show that the interaction coefficients of both scale variables decrease with the increase of their values.By the approximate linear method，the nonzero equilibrium point of system evolution is proved to exist，and the factors that have a pure negative effect on the stability of the evolution equilibrium point are oblained.The economic belt system is more prone to phase transition in the equilibrium state when those factors are large.A proper length of shipping passage is conducive to the stable development of its economic belt.
