摘要

本文在以往文獻對垂直分工度測量指標研究的基礎上，進一步對垂直分工度比重(VSS)的測算公式進行推導，得出一個計算整個國家和各個行業國際垂直分工度指數的一般化的理論方法。接著，文章以2004年中國八大製造部門對美國出口中的垂直分工度作為實例，通過整合投入產出表部門分類法和聯合國標準分類法的統計研究，運用數學Matlab軟體對八大部門出口的垂直分工度進行測算。測算過程和軟體運行證明，引入新的技術方法和新的統計口徑之後，垂直分工度的測算在理論和技術上的難度大大降低，為今後的學術研究提供了一個清晰的研究思路。

This paper has further derived the formula of the VSS computation on the basis of the former research, obtained a general method in theory of calculating the VSS of the country and every department. And then, taking the departments of manufacturing industry in 2004 as an example, the article has combined the criteria for classification of input-output table and SITC, used the programs of the Matlab and calculated the VSS of the eight departments. The calculating course and the result prove that: introducing new computing method and classification criterion, it reduces greatly the difficulty of calculating the VSS, theoretically and technologically. This paper contributes much to the further research for a clear thinking.
