與傳統(tǒng)理論不同，新增長理論和新貿(mào)易理論都強調(diào)技術(shù)進(jìn)步的作用，因此本文構(gòu)建了一個三部門的技術(shù)外溢效應(yīng)模型(國內(nèi)部門、工業(yè)制成品出口部門以及初級產(chǎn)品出口部門) ，考察了工業(yè)制成品出口和初級產(chǎn)品出口對國內(nèi)非出口部門不同的技術(shù)外溢效應(yīng)；第四，從更加廣闊的視野就貿(mào)易開放度與中國經(jīng)濟增長問題進(jìn)行研究，有關(guān)貿(mào)易開放度如何度量一直是存在較大爭議的問題，本文首先對該類研究文獻(xiàn)進(jìn)行了較為詳盡的述評，然后運用生產(chǎn)函數(shù)方法對所選取的5個貿(mào)易開放度度量指標(biāo)進(jìn)行了檢驗，結(jié)果發(fā)現(xiàn)盡管一些已有研究認(rèn)為外貿(mào)依存度無法真實度量一國經(jīng)濟開放水平，但是本文研究結(jié)果表明外貿(mào)依存度仍是度量我國貿(mào)易開放度的較好指標(biāo)，進(jìn)一步采用基于var系統(tǒng)的脈沖響應(yīng)函數(shù)法以及預(yù)測誤差方法分解法對貿(mào)易開放促進(jìn)經(jīng)濟增長的作用進(jìn)行了動態(tài)刻畫。 - The same conclusion as derived from the original pda under approximate condition is concluded this way without any approximations . the second method is the instant - state performance prediction based on the hyca method . this method not only gives the off - line recursive error variance relation , but also gets a series of performance measurement such as track life
