本文以超越對數隨機邊界生產函數，探討屬貨櫃航運產業的H海運公司各定期航線之營運效率及其影響因素。針對該個案公司歐洲、美洲、亞洲及大西洋等21條定期航線，2003至2006年的季資料進行估計後，主要發現如下：第一，在樣本期間中，受到全球景氣之衝擊，以2004年之效率較差，而2006年之效率則相對較佳。第二，若以航程別言，去程航線較回程航線有效率；另以航線別言，則以亞洲航線最有效率、歐洲航線次之、大西洋航線再次之，美洲航線最無效率，顯示美洲航線有較大之改良空間。第三，將航程與航線交叉分析時發現，亞洲航線去回航程之營運效率較其他航線為高，顯示歐洲、大西洋及美洲等航線之回程產能較具潛在改良的空間。最後，在季別效果上，以第四季之效率最低，而第一季之效率則相對最佳。綜合而言，相對於過去以整體貨櫃航運產業為分析對象之文獻，本研究改以個案公司內部航線微觀層次資料進行分析，或許較能提供更具體資訊予企業的管理階層，做為擬訂經營決策之依據。 Liner shipping plays a major role in international trade. This industry is always keen to be quite competitive as it is in the midst of structural changes such as high market centralization, formation of big strategic alliances and scale enlargement. Therefore, encountering such shifts in business practice, how to evaluate the effectiveness and efficiency for each route is then very vital for any liner shipping company. This paper estimates the production efficiency for a liner shipping company by using the conversion logarithms of stochastic frontier production function and also investigate what environmental factors influence production inefficiency. Summarizing the empirical study, the conclusions are as follow: First, The efficiency of outbound is better than inbound. Second, to compare with the ship routes, the efficiency of the Asian Route is the best, the European Route is second, the Atlantic Route is third and the American Route is the worst. Finally, the efficiency of quarter 1 is the best and the quarter 4 is the worst. Compared with the past papers which focus on the level of industry, case study could provide more useful information which use microcosmic data to management to make decisions.
