After the financial crisis of U.S. in 2008，Japan’s economy fell into a second recession. After Abe came to power，a series of policies including a loose monetary policy、proactive fiscal policy and structural reforms are implemented to stimulate the economy. The Japanese economy temporarily gets out of the recession with a restorative growth. But in the long run，the effect of Abenomics is limited. Japan’s economy is still subject to the impact of other factors，such as the reduction of labor force，a surge of government debt and the decrease of total factor productivity. The current long-term downturn of the Japanese economy is unlikely to be changed.
