Under the global value chain,a country extensively employs foreign intermediate inputs in manufacturing its export products,which may not employ entirely local technology.Science-based measurement of technology content in and structure of exports should be conducted using production process data.Using world input-output tables(WIOTs)of 1995-2011,this paper developed a new method for measuring the export technology content of China and other major countries.Our research findings suggest that,since 1995,there has been some technology upgrade of Chinese exports.China’s overall and sector-specific technology contents,and domestic technology contents and indexes all increased and demonstrated a weak convergence towards the average level of developed countries.Judging by the relative rankings of sector-specific technology levels,China is almost locked at the lowest level in the world,and cannot challenge the technological superiority of developed countries like the U.S.and Japan.
