In the process of economic globalization, the production is characterized as fragmentation. A new pattern of international division of labor characterized by global value chains is strengthening. The production procedure is dispersed to different countries in the range of design, raw material purchase, parts manufacturing, processing and assembly, and sale. The value and profit are obtained by different firms from different countries. Traditional trade accounting method has problem of double accounting and overvalue, that is hard to measure the real trade benefit of a nation. We can use indicator of “value-added export” to calculate export benefit. It reflects domestically added value from export, which contains direct value, and indirect value generated from relative industries. Traditional export statistical method does not filter away the repeated calculation [1]. Recently, it is popular to do empirical research with value-added export. There are two kinds of research. First, vertical specialization index method is used early, which is proposed by Hummels in 2001 [2]. Hummels used input and output data to make analysis to the imports volume involved in exports, and intermediate goods from direct export. Lawrence J. Lau (2007) use vertical specialization index and non-competitive input-output data to measure domestically added value from export [3]. However, the method has obvious flaws that do not refer to the added value arising from re-exports of third countries. Using World Input-Output Database (WIOD) to do empirical research is becoming more and more popular. For example, Koopman (2012) apply Single-Region Input-Output (SRIO) model to analyze. But the method cannot reflect the economic relationship between countries. So, it is suitable to make analysis with Multi-Region Input-Output (MRIO) model. For example, Shuijun Peng (2015) use WIOD, MRIO and Structural Decomposition Analysis to calculate carbon emissions of consumption and production of China [4]. Ming Ge (2015) also apply it to analyze the volume of value-added export and import, and the determinants [5]. Yunfeng Yan (2016) also apply it to analyze trade competitiveness of APEC economies [6]. The paper mainly refers to the empirical research of Shuijun Peng and Ming Ge to make analysis.
