Therefore, a model of three sectors, respectively referring to domestic sector, manufacturing export sector and primary product export sector, has been established here to measure the technology spillover effects of export on domestic sector. finally, based on a broader framework, this dissertation went on to investigate the relationship between openness and china ' s economic growth, while the result shows that though there exists a notable dispute about how to measure the degree of china ' s openness, the index of trade dependence still maintains the better one to reflect china ' s economic openness. in the meanwhile, impulse response function ( irf ) method and forecasting errors variance decomposition ( fevd ) method, both of which are based on the vector auto - regression ( var ) system, are used here to investigate the dynamic relationship between openness and china ' s economic growth
與傳統理論不同，新增長理論和新貿易理論都強調技術進步的作用，因此本文構建了一個三部門的技術外溢效應模型（國內部門、工業製成品出口部門以及初級產品出口部門） ，考察了工業製成品出口和初級產品出口對國內非出口部門不同的技術外溢效應；第四，從更加廣闊的視野就貿易開放度與中國經濟增長問題進行研究，有關貿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進行了較為詳盡的述評，然後運用生產函數方法對所選取的5個貿易開放度度量指標進行了檢驗，結果發現盡管一些已有研究認為外貿依存度無法真實度量一國經濟開放水平，但是本文研究結果表明外貿依存度仍是度量我國貿易開放度的較好指標，進一步採用基於var系統的脈沖響應函數法以及預測誤差方法分解法對貿易開放促進經濟增長的作用進行了動態刻畫。 -

The results indicated that as the intensity of sward cleavage increased, elymus nutans and other plants that had high requirements in soil aeration and resource space presented an increased competitive edge and the species that had low requirements in soil aeration and resource space presented an opposite picture ; low - intensity sward cleavage could help increase species diversity to a certain extent, but the diversity index appeared to decline as a whole as the cleavage intensity increased ; the effects of sward cleavage on functional groups of the vegetations showed in such manner as e. nutans - represented grasses increased in their composition with the intensity of sward cleavage raised, and sedges and forbs decreased in their compositions with the intensity of sward cleavage raised ; sward cleavage showed a significant improving effect on primary productivity of the meadows and was capable of increasing the proportion of quality - grass biomass to the total plant biomass ; sward cleavage could be independently employed as an effective measure to rehabilitate and improve alpine - meadow grasslands and thus played a basic and key role in the technical combination aiming at establishing hay fields characterized by e. nutans
結果表明：垂穗披堿草等對土壤通透性和資源空間要求較高的物種，競爭力隨劃破強度的增加而上升，而對土壤通透性和資源空間要求相對較低的物種則相反；輕度劃破干擾對提高物種豐富度具有一定的促進作用，但多樣性指數則總體上表現為隨劃破強度的增加而呈下降的趨勢；劃破干擾對植被功能群的影響表現為以垂穗披堿草為代表的禾草類組分隨干擾強度的增加而顯著上升，莎草類和雜類草組分隨干擾強度的增加而顯著下降；劃破干擾對草地初級生產力的提升具有顯著的促進作用，且可顯著增加植物總量中優質牧草的比重；劃破干擾可獨立作為高寒草甸類草地恢復與改良的有效措施，在定向培育垂穗披堿草型割草場的技術組合中具有核心和基礎性的地位。 -
