    Abstract: 本文建立一個垂直相關市場的理論模型,於存在可自由進出的中間財
    市場下,分別探討最終財廠商在浮動價格契約與固定價格契約下的研發決
    策及其對中間財價格的影響。本文發現,在浮動價格契約下,當中間財廠
    商可以自由進出市場時,無論最終財廠商之研發是否會產生外溢效果,均
    不會影響中間財價格。再者,在中間財市場為一可自由進出的結構下,下
    游廠商研發投入會高於在上游廠商家數外生給定為一家的情況。最後,若
    廠商從事研發會產生外溢效果,則隨著外溢效果增加,儘管最終財廠商的
    研發投入量會隨之減少,但其產量卻會呈現先增後減的變化。上述發現均
    與過去相關文獻所得之結果明顯不同。;This paper establishes a vertical-related model in which intermediate goods market is free entry to discuss the research and development (R&D) of downstream firms and the impacts of downstream firms’ R&D on the price of
    intermediate goods under floating price contract and fixed price contract.
      The major findings of this paper are that: first, under the floating price contract, the price of intermediate goods won’t be affected by the R&D decisions of the downstream firms when the intermediate goods market is free
    entry, regardless of R&D spillovers; second, the amount of R&D under the case that the intermediate goods market is free entry will be more than that the
    intermediate goods market is monopoly; last, if there exists R&D spillovers, the R&D level of downstream firms will decreases but the quantities will increase at
    first then decrease with the spillover effects. The above results are quite different from the previous literatures’ conclusions.
