Research on China's Interregional Trade in Value-Added from the Perspective of Value Chain

Abstract

The statistical accounting of international trade is often based on the gross value method of customs data. With the maturity of the global value chain, the international division of labor is becoming more specialized, and the trade of intermediate products is becoming more frequent. The gap between the statistical results of the traditional gross value trade accounting method and the real trade situation is widening. This paper uses the value-added trade statistical model and China's interregional input-output data to calculate the value-added trade volume of China's eight regions in 2002, 2007 and 2010, compares it with traditional statistical methods, and establishes an empirical model with value-added trade as the explanatory variable. The study found that the gross trade statistics method would distort the trade volume and exaggerate the degree of trade imbalance; Trade scale, R&D investment, fixed asset investment, employment scale and other factors will significantly affect the scale of value-added trade.
