【Abstract】 This paper uses the DID method to empirically analyze the impact of"the separation of core and non-core business and the reconstruction of non-core business"of large-and mediumsized state-owned enterprises on innovation. We find that the reform promotes the innovation of enterprises with regard to inventive patents and utilitarian patents but not the design and appearance patents. Further analysis shows that: Firstly,the reform promotes the innovation of enterprises mainly by improving the innovation efficiency. Secondly, if we did not put the"reconstruction of non-core business"into practice,the business separation would not significantly promote the innovation of enterprises. Finally,the effect on innovation is stronger in industries and regions who has intenser market competition. The above analysis shows that the burden lightening can enable enterprises to "go into battle " effortlessly and build a fully competitive market environment,which will help to improve the effectiveness of the reform on state-owned enterprise.更多还原
