China's local spending drives economic growth more than central expenditures.
The study looked at how China's fiscal policy affects its economic growth. They found that local spending growth has a bigger impact on the economy than central spending growth. Changes in taxes didn't always lead to more economic growth due to money constraints. In the past, investing in manufacturing helped the economy the most, but now investing in research and development is more important. Also, having a lot of debt affects China's government income.
