A Research of Domestic Value Added of Chinese Manufacturing Export Trade and Its International Comparison of Influential Factors

In order to reflect truly China's international trade situation and the real benefits obtained though trade, we use the non-competitive multi-regional input-output model and calculate the domestic value added of exports trade of 8 major economies in manufacturing sector during the period of 1995 and 2011. Then we do structure decomposition analysis of influential factors. The results show that: (1) Throughout the study period, the gap between export scale in the method of traditional customs statistics and the domestic value added of exports significantly increased; (2) For China: except changes of directly value added coefficient, the expansion of export volumes, changes of intermediate inputs technology and export structures promote the growth of domestic value-added of export trade, and export scale change is the main reason for its growth;(3) Export expansion is the most important reason for the growth in manufacturing exports of domestic value added in 8 major economics. Except the US, changes of directly value added coefficient suppress the growth of domestic value added of export trade. Meanwhile, changes of intermediate inputs technology in India, Brazil, the US and Germany lead to the decrease of the domestic value added of export trade, and except Korea, changes of export structure suppress domestic value added of manufacturing exports.
