Abstract: 在海運貿易市場的蓬勃發展下,船舶繁密地航行在各大洋間,頻繁的船舶航次顯示了港口的興盛與繁忙;在這樣大量航次下的貿易需求,使得船舶在錨區排隊等候現象時有所聞。面對這樣的船舶等候問題,運輸經濟研究學者提出「減少需求」:「以價制量」的觀點,探討透過收費來分散船舶過於密集的抵達狀態,進而舒緩船舶等候現象。而目前船舶等候定價傳統模式已發展出單至多階段之階梯式收費架構,用以消除不同程度之等候現象。 然在船舶等候定價傳統模式中,吾人已知船舶之排隊等候時間成本的價值均相同,且船舶報到時間要求為精準時刻。此狀態則與目前海運現況有所落差,例如不同船舶性質或種類的船舶,其排隊等候時間成本之價值之衡量應有所差異,以及管理單位允許船舶報到時間有一定的緩衝範圍而非精準時刻。故本研究將船舶等候定價傳統模式進行改良,考量不同性質或種類的船舶排隊時間成本價值有所差異,以及船舶報到時間放寬為彈性時段而非單一時刻,從而建構出船舶等候定價改良模式,使改良模式能夠更加貼切於港務實際現況。 船舶等候定價改良模式首先確立船舶抵達型態後,建構收費實施前之船舶均衡成本,以收費取代等候時間成本之概念,推導出改良模式下之零等候彈性收費架構與階梯式彈性收費架構。以瞭解收費對於排隊等候之消除效果。研究同時也探討過往未曾討論關於收費實施前後每一艘船舶抵達時刻的改變,以了解收費實施前後所有船舶抵達錨區時的分散效果與移動變化,藉此分析收費造成船舶改變行為之因果關係。 本研究同時也將船舶等候定價傳統模式與改良模式進行比較,以瞭解兩種模式之差異,以及改良前後之優缺點。最後則藉由蒐集高雄港與巴拿馬運河相關統計資料與港埠相關成本之實務數據,編寫程式進行數值分析,提供傳統與改良模式下之數值模擬結果,以作為港務單位與航商之收費參考依據。
Under the vigorous development of the shipping market, ships are sailed densely among the oceans. Frequent ship sailings show the prosperity and bustling of the port; the trade demand under such a large number of sailings makes the ship wait in line when the ship is queuing at the anchor zone. In the face of such ship queuing problems, transport economics scholars have proposed "reducing demand": "in the form of price system", to explore the excessively dense arrival of ships through tolls, thereby relieving ship queuing. At present, the traditional model of ship queuing pricing model has developed single to multiple-step toll structure to eliminate the queuing phenomenon. However, in the traditional model of ship queuing pricing model, we know that the value of the queuing time cost of the ship is the same, and the ship registration time requirement is a precise time. This state is different from the current maritime status. For example, the value of the queuing time cost should be different for ships of different types, and the management allows the ship to have a certain buffer range rather than a precise time. Therefore, this study will improve the traditional model of queuing pricing model, considering the difference in the cost of the ship's queuing time of different natures or types, and the relaxation of the ship's registration time into a flexible time period rather than a single time, thus constructing a ship queuing pricing improvement model. The improved model can be more closely related to the actual situation of the port. The ship queuing pricing improvement model. first establishes the ship arrival type, constructs the ship equilibrium cost before the implementation of the tolls, replaces the queuing time cost with the toll, and derives the optimal time-varying flexible toll structure and the stepped flexible toll structure under the improved model. To understand the effect of charging on the elimination of queues. The study also explored the changes in the arrival time of each ship before and after the implementation of the tolls, in order to understand the dispersion effect and movement changes of all ships before and after the implementation of the toll, to analyze the causal relationship between the changes caused by the charges.
