In past 2018，the overall profitability of Chinese listed companies declined，the level of corporate governance improved，the standard of information disclosure improved，the amount of R&D investment slowed down，and the strength of social responsibility increased. However，there are still many worries，such as insufficient financial performance robustness，outstanding corporate governance problems，and the incredibility of internal control. Based on financial data of listed companies，we evaluated the effectiveness of supply-side structural reform. Firstly，the resistance of capital recovery to entity enterprise is still large，because real sector investment yield is low. Secondly，the results of the adjustment of economy structure show that：the effect of industrial structure upgrading has begun to appear，the enthusiasm for mergers and acquisitions has greatly faded，the motive force for innovation investment has been exhausted，and the vitality of private economy needs to be activated. Finally，the results of the five major tasks show that：it is still difficult to get rid of production capacity，and enterprises have a strong incentive to increase production；there are coexistence of destocking and inventory replenishment in different industries；long-term solvency is strengthened，and short-term solvency is declined；operating costs and tax burden are reduced，but labor compensation costs are increased；the rate of return of weak industries is increasing，and the pace of making up for shortcomings is expected to accelerate.
