【摘要】At present,it is urgent for industrial study and trade practice to devise rationally a set of measurements and assessing criteria,which can reflect the extent of vertical disintegration in China's manufacturing.Based on Campa and Golderg's measurements of intermediate goods in imports and the VS measurements of Hummels et al,this paper,using input-output methods,has set up four VD indice of intermediate goods in imports,exports,internal sales and home increasing in exports. Furthermore,we have measured the extents of vertical disintegration in China's manufacturing.The empirical studies have shown that this measurements and index systems are strength in explaining reality and policy implication.
