腹地状况是决定港口成长的关键,但腹地发展的哪些因素对港口成长的作用最大,这些因素如何影响港口发展,这些问题的研究仍没有形成系统和普遍共识。另一方面,腹地存在不同的地域空间层次,港口发展的不同阶段与腹地联系的地域空间层次也不尽相同。该研究首先运用灰色关联度模型测算了辽宁沿海6个城市、辽宁省以及东北三省3个空间层面的腹地与辽宁沿海港口成长的关联程度,得出沿海港口群与东三省的关联度最高。在此基础上,构建港口成长的影响因素指标体系,运用脉冲响应分析探讨了9个因素对港口作用的动态变化过程,从而揭示不同因素对港口影响的内在动态作用过程。据此,将影响港口发展的因素概括为拉动型、有限促进型、波动型和滞后型4个类型。最后,探讨不同因素对港口成长作用存在差异的原因,进而提出辽宁沿海港口今后的发展战略。
Hinterlands' conditions are key determinants of port growth. However, researches concluding which are the largest significant factors of hinterland to the growth of port and how these factors influence port development still do not form a sys- tem and some common consensus. On the other hand, because of different geographical spatial hierarchies of hinterland, the con- nection between port development at different stages and hinterland is also different. Firstly, this study measures the connection degree between hinterlands and Liaoning coastal port growth with grey correlation model in three dimensional levels,which are the Liaoning coastal six cities, Liaoning province and the three northeast provinces. The conclusion is that the highest correlation with coastal ports group is three northeast provinces. On this basis, it constructs indicator system of influencing factors of port growth and discusses the dynamic change process that the port is affected by nine factors based on impulse response analysis. Thus it reveals internal dynamic process that different factors impact on port. So factors affecting the development of port are summarized into four types: pull,limited promotion,volatility and hysteresis. In the end, it discusses the reasons why there are differences in different factors' effects on port growth. Then development strategies of Liaoning coastal ports in the future are put forward.
