貨物運輸產業在現代化發展下，發展出軸輻式網路的概念，各家業者以此建構內部運輸網路來提升貨物運輸的效率及降低成本。隨著貨運業之競爭越來越激烈，市場上的新進業者(follower)無不希望發展更有效率的網路結構，與既有業者(leader)分食版圖。
本研究提供的「寄附式軸輻網路」給予新進業者一個進入市場的方式：透過將自身網路寄附在既有業者的網路下，將後段運輸服務寄附委外給既有業者的中繼站，由既有業者負責到著的運輸，此方法讓新進業者於擴展服務區位同時又能減少固定資產的投資。本研究依此建構一個數學模式，並以台灣業者提供之數據做實證測試，以Lingo軟體求解最佳化利潤，並分析新進業者在貨量提高的過程有何網路經濟效益。
本研究發現，寄附式網路的設計可有效減少總成本，使新進業者有更好的利潤。而隨著貨量增加的過程，先開設集貨站、營業所來增加通過中繼站的不同起迄對節線是發揮範疇經濟的效果；而開設中繼站後通過的起迄對減少、單一起迄對節線貨量增加則是規模經濟的效果。此寄附式軸輻網路設計中，貨量逐漸增加的過程，範疇經濟比起規模經濟會優先發揮效益。

Hub-and-spoke network is applied to promote the efficiency of delivery service and reduce cost. Since the booming of carrier industry, it is necessary to followers at market to develop a helpful network structure to increase the profit. The research provide the follower a new way of entering the market through outsourcing the goods to leader’s hub. Based on this network design, the leader will be responsible for the preload sort and deliver goods to recipient. This operations network can both reduce the fixed cost of facilities and expand the scope of service. The research construct a mathematical model and make a computational study in Taiwan. To maximize the follower’s profit, we solve the problem by Lingo software and analyses the result to observe the economic benefits of this network. We find that this auxiliary hub-and-spoke network design can reduce the cost effectively. As the number of demand increasing, a follower will build dropoffs or centers at first with small volume due to the benefits of economy of scope. With the volume increasing more, economy of scale has greater effects so that the follower will build hubs.
