中国高技术制造业出口国内增加值的测算及影响因素分析

借鉴Koopman等关于增加值贸易的计算方法,利用1995—2011年的世界投入产出数据,文章测算了中国高技术制造业出口的国内增加值。在观察期内,以出口的国内增加值衡量的贸易规模增长了17倍,但以出口的国内增加值率衡量的贸易利得却下降了25%。研究表明,中国高技术制造业出口的国内增加值提升的主要动力依然来自于产业的规模经济和比较优势,二者的贡献率分别达到了75%和41%；而技术创新的促进作用仍然十分有限,贡献率仅为4%；此外,中国高技术制造业目前较低的国际分工地位也明显不利于其出口国内增加值的提升。

Analysis of the Measurement and Influencing Factors of Domestic Value-added in China's Exports of High-tech Manufacturing

This paper calculates the domestic value-added in China''s exports of high-tech manufacturing using the multinational input-output data in WIOD database during the period of 1995-2011 based on the measurement of Koopman et al.(2012). During the observation period, the scale of trade increased by 17 times, but decreased by 25% measured by the domestic value added rate of exports. Empirical research shows that the main driving force for the increase of domestic added value of China''s high-tech manufacturing exports still comes from the scale economy and comparative advantage, with their contribution rates reaching 75% and 41% respectively. But the promotion role of technological innovation is still very limited, with the contribution rate being only 4%. Inversely, the position in global value chain significantly decreases it.
