What's the Difference - Comparing U.S. and Chinese Trade Data. Updated April 21, 2010

摘要

There is a large and growing difference between the official trade statistics released by the United States and the People's Republic of China. According to the United States, the 2009 bilateral trade deficit with China was $226.8 billion. According to China, its trade surplus with the United States was $143.3 billion-$83.5 billion less. This paper examines the differences in the trade data from the two nations in two ways. First, it compares the trade figures at the two digit level using the Harmonized System to discern any patterns in the discrepancies between the U.S. and Chinese data. This comparison reveals that over two-thirds of the difference in the value of China's exports to the United States is attributable to five types of goods. Those five types of goods, in order of the size of the discrepancy are electrical machinery; toys and sporting goods; machinery; footwear; and furniture. The second approach to examining the differing trade data involves a review of the existing literature on the technical and non-technical sources of the trade data discrepancies, including an October 2009 joint China-U.S. report on statistical discrepancies in merchandise trade data. The literature reveals that the main sources of the discrepancies are differences in the list value of shipments when they leave China and when they enter the United States, and differing attributions of origin and destination of Chinese exports that are transshipped through a third location (such as Hong Kong) before arriving in the United States.
