  1. 運輸經濟學-期末報告- 貨物運輸業者需求 指導老師：李穗玲 航四甲 1094408040 黃邦栩

  2. Vtruck=β1(Truck Rate) +β2(value)(Truck Transport Time) +β3(Value)(Truck Reliability) Vrail =γ2+β1(Rail Rate) +β2(Value)(Rail Transport Time) +β3(Value)(Rail Reliability) Vpiggyback=γ3+β1(Piggyback Rate) +β2(Value)(Piggyback Transport Time) +β3(Value)(Piggyback Reliability) (4.36)

  3. ΔV =β1 ΔTruck Rate ΔV =β1 (4.37) Δ(Value)(Transit Time)(r) But from the model in (4.36), we know that △V =β2 (4.38) △(Value)(Transit Time)

  4. Table 4.1 6 Market shares for 42 manufactured commodities, 1972 (%) Distance Shipped (miles) Truck Rail Piggyback (運輸距離)(英里) (卡車) (鐵路) (平板車) 0-99 78.5 21.3 0.2 100-199 70.3 28.6 1.1 200-299 60.6 37.0 2.4 300-499 51.2 44.2 4.6 500-599 39.4 51.3 9.3 1,000-1,499 35.5 56.4 8.1 1,500 or more 26.9 62.8 10.3 Source: Lvin (1978), table 1, p. 27
