【摘要】 明晰港口城市"绿色增长"的发展机制可为地方政府高层推动港口城市的绿色转型提供参考。本文从港口城市海岸线资源这一自然资本"适度"损害的可能性约束、港口城市GDP与港口吞吐能力之间协同的"稳态"二个关注点构建了适用于中国的港口城市"绿色增长"具有普遍性发展机制的理论框架,运用建立的非线性最优控制模型对港口城市——唐山进行了实例分析,结果表明:减少因港口吞吐能力增长对港口城市海岸线资源的损害比例是保证港口城市"绿色增长"的基本前提;提升港口城市GDP的港口经济贡献度、降低港口城市GDP水平的增长调控系数和因港口损耗等表征港口吞吐能力的自然衰退率则有利于提高"稳态"水平。最后,针对不同控制因素的预期影响,提出了相应的建议。更多还原

【Abstract】 A clarification of "green growth" development mechanism of city-ports can provide "reference" for local government decision makers to promote the city-ports green transformation. The paper develop a theoretical framework on "green growth" development mechanism which is a universal one suitable for Chinese city-ports by a perspective on two concerns, one is a possible constraints of "moderate" damage on natural capital which can be described by city-ports coastal resources, the other one is city-ports’ GDP and ports’ cargo-handling capacity co-evolve and are drawn towards a steady state. Subsequently, a nonlinear optimal control model is established and applied to the city-port Tangshan. The Case study results show that reduce damage ratio on city-ports coastal resources due to the promotion of ports’ cargo-handling capacity is the basic premise of ensuring "green growth" of city-ports, and enhance the economic contribution of port to city-ports’ GDP and reduce the coefficient of city-ports’ GDP growth speed of adjustment and the depreciation rate of ports’ cargo-handling capacity due to the natural loss can lead to a higher "steady state". Finally, corresponding suggestions are put forward for expectations of the above different controlling factors.更多还原
