Abstract: Since 2009, the bilateral trade balance of optoelectronic equipment manufacturing industry has accounted for more than 40% of the total trade deficit between China and the United States. Analyzing the bilateral trade imbalance of optoelectronic equipment manufacturing industry has important practical significance for revealing the real trade situation between China and the United States.The rise of global value chain theory system provides a more scientific research framework for re-examining bilateral sector trade. This paper uses WIOD inter-country input-output table and value-added trade accounting method to decompose Sino-US bilateral trade in optoelectronic equipment manufacturing industry from 2000 to 2014 in terms of trade scale, product structure, industrial linkages and country structure.The research shows that the bilateral trade imbalance between China and the United States in optoelectronic equipment manufacturing industry under the traditional trade statistics model is exaggerated; although China does have a trade surplus with the United States, China′s profitability in bilateral trade is relatively weak compared with the United States, China′s share of domestic added value in bilateral exports is lower than that of the United States, and the final product export is the main factor; although the production capacity of China′s industrial intermediaries products is not continuously strengthened, but its position in the global value chain is still lower than that of the United States; the degree of electronic informationization and service-oriented in American industry is relatively high, while the service industry investment in China′s optoelectronic equipment exports shows an increasing trend year by year; the major trading partners in the bilateral trade network of optoelectronic equipment between China and the United States are relatively stable,Among them, Mexico′s importance is increasing while Japan′s status is declining.

Key words: global value chain, Sino-US bilateral trade;value added of Optoelectronic equipment manufacturing
