In past 2019，the profitability of Chinese listed firms continued to decline，the level of corporate governance improved slowly，the standard of information disclosure improved，the intention of innovation investment improved，and the sense of social responsibility has increased. Based on financial reports of listed firms，we evaluated the effectiveness of supply-side structural reform. Firstly，market capital remained in the virtual economic system，because real sector investment yield is low. Secondly，the results of economy structure adjustment show that：the effect of industrial structure upgrading has appeared，the enthusiasm for mergers and acquisitions has risen，the motive force for innovation investment has increased，and bank asset quality has improved. Finally，the results of the five major tasks show that：Capacity reduction is coming to an end，and enterprises have a strong incentive to increase production. Destocking is coming to an end，and inventory replenishment indifferent industries. Deleveraging is coming to an end，and stabilizing leverage becomes the focus. Tax burden and labor compensation costs are reduced. The return of weak industries investment is increasing，and the pace of making-up for shortcomings will accelerate.
