An empirical analysis of China's aggregate import demand function

摘要

This study uses the cointegration concept to analyze the long-run relationship of China's aggregate import demand function for the period 1970-1999. The conventional specification for the import demand function reveals that the volume of imports demanded responds to domestic activity and relative prices. This study considers four definitions of domestic activity, namely gross domestic product (GDP), GDP minus exports [IMF Staff Pap. 45 (1998) 236], "national cash flow" [Econ. Lett. 74 (2002) 265], and final expenditure components [Appl. Econ. 21(1989) 957]. The empirical results indicate a long-run equilibrium relationship between these measures of domestic activity and China's import demand. Overall, domestic activity and relative prices are inelastic in the long run. This study also highlights some policy implications.
