Abstract: This paper analyzed the effect of intermediate goods on skill wage gap and theoretically proved that the effect of it varied in different labor conditionsIn the condition of unlimited labor supply skill wage gap was determined only by the absolute demand of skilled laborWhile intermediate goods trade could increase the latter, it would necessarily increase skill premiumBut when labor condition converted to limited supply, skill wage gap would be determined by comparative demand of skilled laborHowever intermediate goods trade could not necessarily increase the latter, in those sectors such as lowtechnology industries where the substitution possibility between skilled labor and unskilled labor was high intermediate goods trade tends to lower the comparative demand of skilled labor and skill wage gapUtilizing the panel data from 33 industries of 5 years, this paper verified above propositions
