Abstract: China's outbreak of Covid19 happened at the beginning of 2020 was effectively controlled within only two months, which was benefited by better play of the government role enriching the profound meaning of the relations between government and market in the practical way. The gap of mobilizing ability between the two systems, which causes the change of supply systems, determines different roles of government and market on fighting against Covid19. It has been found that market supply has its innate short board in tackling outburst external shock, while the strength, stability and accuracy of government supply under the external shock outweigh the market supply in overall importance, timeliness and quality of supply. Considering the enhancement of economy system defense power and immunity to create favorable conditions for achieving overall social goals, we further make a beforehand, middle and afterwards exploration of dynamic relations between government and market supply, corresponding to the execution level of government response, disposal, recovery and sustainable development respectively, which could help improve and deepen the recognitions of the relations, and moreover, provide great inspirations of modernizing China governance system and capacity for governance.

摘要： 2020年年初发生于我国的新冠疫情在两个月时间内得到有效控制，这得益于政府作用的更好发挥，也从实践层面深化了政府与市场关系的内涵。政府和市场两大体系动员能力的差异所导致的供给体系变化直接决定了政府和市场在抗击疫情的目标中所扮演的角色。抗击疫情的实践表明，市场供给在应对突发外部冲击时存在“调节短板”，政府供给所体现的“强、稳、准”特征，使得外部冲击下的政府供给在全局性、时效性和供给质量上都要优于市场供给。考虑到经济体系的防御力和免疫力提升问题，从而为社会整体性目标的实现创造有利环境，本文又进一步从“应变-处置-恢复与可持续发展”这一政府执行层面对政府供给和市场供给的动态关系进行“事前-事中-事后”的全链条考察，进一步完善和深化对政府和市场关系的认识，以期为提升我国国家治理体系和治理能力现代化水平提供有益启示。
