After the period of European Sovereign Debt crisis，the German economy performs healthily：Economic growth is sustainable；employment continues to improve；prices are stable，fiscal budget is balanced and public debt decreases. However，some unrest appears behind healthy appearances，such as slight weakness of foreign trade；downside risks of economy；signs of deflation，etc. Under this background，the German government has implemented a series of economic policy adjustment：further promotion of industry 4.0， introduction of digital agenda，improvement of the energy policy，reform of the pension system，implementation of the minimum wage，etc. These measures have a positive effect on promoting economic growth and improving unfair income distribution in Germany，but they also contain the potential risks，such as increasing pensions may threaten the sustainability of the whole welfare system，etc.
