Capital flows, economic growth and the real effective exchange rate: Evidence from China

This paper examines the Granger causal relationship between capital flows and economic growth in China over the period 1998Q1–2019Q2, allowing for real effective exchange rate (REER) effects. As parameter instability tests indicate structural changes, we use bootstrap rolling window causality tests, which suggest that the causal nexus between capital flows and GDP growth is time-varying. We find that the causal links between foreign direct investments (FDIs) and GDP growth are hardly affected by the REER, whereas the REER plays a more important role in affecting the causal connections between portfolio investments and other investments and GDP growth. Our results suggest that cumulative portfolio inflows and cumulative other investment inflows harm GDP growth, whereas cumulative portfolio outflows and cumulative other investment outflows positively affect GDP growth.
