近年來因為海運市場變化，貨櫃航商產生整併及海運聯盟重組行為，進而重行配置航線並選擇航線泊靠港口，以達成本最小化及效益最大化，而這也使東亞港口間之競爭白熱化。為了解此波海運聯盟重組後，港口彼此間競爭關係，本研究就「影響港口競爭力之重要因素」、及「港口競爭力評估方法」進行文獻回顧，並加以整理、分析。以專家問卷方式，運用層級分析法（AHP，Analytic Hierarchy Process）進行各港埠競爭力評估準則之相對重要性（權重值）分析；另利用灰色關聯分析法（GRA，Grey relational analysis）評比高雄港及廈門港現況之相對競爭力、及其個別競爭資源優勢。
研究結果發現，「航商營運策略」係為2017年海運聯盟重組後，航運專家最為重視之構面，其次依序為「港口外部條件」、「港口內部條件」；「航商營運策略」構面的4項評估準則，整體權重值均列前6名；高雄港現階段競爭力仍略優於廈門港，惟須持續觀察航商營運策略；廈門港在「腹地貨源因素」相較高雄港而言極具競爭優勢，且在「港口發展規劃」、「港口當局獎勵措施」亦優於高雄港。
本論文依據研究結論作出兩點建議，除應持續觀察高雄港重點航線及外籍航商營運情形外，亦應整合本身優勢及發展附屬營運項目，以提高港口服務效益。最後並就未來值得進一步研究的課題，提出研究方向。

In recent years, due to changes in the maritime market, container operators have developed consolidation and maritime alliance reorganization activities. In order to understand the current competitive relationship between Kaohsiung Port and Xiamen Port after the reorganization of this maritime alliance, the present study reviews the important factors affecting port competitiveness and evaluation methods, lists 12 evaluation criteria for 3 facets, and uses the Analytic Hierarchy Process and Grey Relational Analysis to evaluate the current competitiveness of Kaohsiung Port and Xiamen Port . The study finds that the "Container Operator Operation Strategy" is the most important aspect for shipping experts after the reorganization of the Maritime Union in 2017; Kaohsiung Port is still slightly better than Xiamen Port at this stage, but it must continue to observe the operation strategy of the container operator; Xiamen port has a competitive advantage in the "Hinterland Supply Factor" and is superior to Kaohsiung Port in the "Port Development Plan" and "Port Authority Incentives ".
