How much are net exports contributing to China's growth?
Core argument: With exports around 20% of Chinese GDP, the 10-percentage-point gap between export and import volume growth implies a net exports contribution to China's growth of close to 2% of GDP.
China’s weak domestic economy and ever-expanding production capacity, juiced with an explicit policy of directing state bank credit toward manufacturing, has led to a surge in Chinese exports. Because Chinese export prices are falling (think of the price of a solar panel), export volumes have been growing much faster than the dollar value of Chinese exports. The phenomenon is clear in their export volume data released by the General Administration of Customs of the People’s Republic of China (GACC) as well the global data compiled by Dutch CPB. On a year-over-year basis, Chinese export volumes are up 13% (data through November, so it will be close to the 2024 annual number) while import volumes are only up 2%. With exports around 20% of GDP, the 10 percentage point gap implies a net exports contribution to Chinese growth of close to 2% of GDP.
