Abstract: In recent years, many countries in ASEAN have depended significantly on products imported from China. This study presents the analysis of dependence level of inputs imported by Vietnam from China. Using production elasticity index as the measurement, the results of research shows that the imported inputs from China are effective for Vietnam’s economy. In addition, in comparison to the inputs imported from other remaining countries in the world, the import from China brought higher production efficiency for Vietnam in most of the industries.
