Abenomics has launched and implemented for four years，and it has different policy effects in micro and macro economies. As for its microeconomic effect，the income of enterprises and employment has improved. As for its macroeconomic effect，the economic growth rate still remains low and the consumer price index（CPI）continues to decline. The serious problem of aging population in Japan has led to the decline of private consumption and equipment investment，as well as the weak domestic demand. Since Trump came to power，the world political and economic situation have become even more complicated，which brings new challenge to Japanese economic development. The non-conventional monetary policy led by the Bank of Japan（BOJ）has limited effect on getting rid of deflation，and has not achieved the goal of the 2% growth of CPI. It is urgent for Japan to extend the scope and power of its growth strategy in order to improve the potential growth rate and maintain the momentum of economic recovery.
