What are China's real gains within global value chains? Measuring domestic value added in China's exports of manufactures

This paper aims to investigate China's gains of participating in global value chains (GVCs) in terms of GDP in exports (DVA - domestic value added) and the factors affecting China's gains. The paper decomposes the gross exports of China so as to get the components that make up total GDP in the exports of the country, namely the value-added exports and DVA that are returned from abroad. Then the two components are measured to obtain the scale of GDP in China's exports both on country and sector level. The results show that, firstly, both value-added exports and the GDP in China's exports are less than the traditional gross trade statistics, indicating that there is a gap of real trade gains under GVCs. Secondly, comparing whether the proportion of DVA in total exports, the proportion of DVA in exports of manufactures or the proportion of RDV in total DVA, the gaps between China and the developed countries such as the United States, Germany and Japan do exist. Especially, considering the RDV of China, the proportion is significantly lower than that of major developed countries such as the United States and Germany, indicating that China lags far behind developed countries in the capabilities of supplying high value-added intermediate goods. Lastly, the empirical results suggest that DVA in China's exports has progressively increased in response to the productivity enhancement; research and development (R&D) inputs and capital formation, and the synergies between R&D and vertical specialization affect China's DVA growth in exports positively.
