摘 要:投資部門結構調整是指調整投資資金在各部門之間的分配比例,是國民經濟體系中的重要內容。本文根據投入產出理論建立投資部門結構調整的產出效應機理模型,深入透析投資在部門之間的轉移所帶動的各產業產出的連動效應機理,并以農業為例進行了實證分析。根據研究,投資部門結構調整的產出效應與該產業或產業群的生產直接消耗系數、投資直接消耗系數以及總投資額密切相關。
關鍵詞:投資結構;投資部門結構調整模型;部門產出;農業投資

Abstract:The investment restructuring of sector refers to the ratio adjustment of investment funds between the various departments, which is an important part of national economic system. Based on the input-output theory, the output effects of investment structural adjustment model can built, to provide insights into the linkage and mechanisms of the industry output effects which are driven by the transfer of investment in the sector. Agriculture is empirical analyzed as an example. According to the study, the output effect of sector investment restructuring is closely related to several characteristics of the industry or industries, such as coefficient of direct production consumption, the coefficient of direct investment consumption, and the total amount of investment.
Key words:investment structure; investment structural adjustment model; sector output; agricultural investment

投資部門結構是指投資資金在各部門之間的分配比例關系,相對于投資產業結構主要集中于三次產業結構而言,更加細致地描述了各細分產業的投資比例。部門投資結構調整能夠使產業結構不斷的演進,實現經濟結構的轉變和優化,使勞動、資本和資源從需求萎縮的部門流動到需求擴張的部門,從勞動密集型的部門流動到資本密集型的部門,從產出附加值小的初級加工型部門流向產出附加值大的制造型部門,能夠促進一國的經濟快速、平穩、可持續的增長[1]。二戰后日本將投資的重點放在農業、輕工業、煤炭、鋼鐵部門,快速帶動日本經濟增長;韓國的投資重點經歷了從勞動密集型的輕紡工業,到重化工業,再到電子、汽車等技術、知識密集型產業的一系列過程,通過30多年時間就成為發達國家;在臺灣經濟發展過程中,通過剛開始重點鼓勵農業投資,后來重點增加工業投資發展勞動密集型輕紡產品,再到優先發展資本密集型的重化工業,到現在重點發展技術密集型產業的政策,帶動臺灣工業升級和經濟發展[2]。……
