Abstract The primary premise for smoothing the innovation chain is to format scientific cognition of the differential innovative function undertook by different types of enterprises and the technical economic relations between the enterprises.Based on the data of the listed manufacturing companies' patent forward citations from 2012 to 2018, this paper found that there exist idiosyncratic R&D behaviors among different ownership enterprises.The R&D activities of state-owned enterprises have more assumed the innovative function of basic research, while the R&D activities of private enterprises have more assumed the innovative function of applied research.This paper used the panel Tobit model to empirically analyze the impact of idiosyncratic R&D's knowledge spillover on enterprises' innovation output.The results showed that the knowledge spillover of state-owned enterprises can significantly promote the applications of all kinds of patent, while the knowledge spillover of private enterprises shows a promoting effect on the applications of invention patents and an inhibitory effect on the applications of non-invention patents.And the level of influence varies among the enterprises with different ownership or different stages of life-cycle.This paper contains the following policy implications.During the process of constructing a new national innovation system based on the innovation chain, state-owned enterprises should be guided into the scientific fields which are highly dependent on basic research in order to solve the problem of market inefficiency and give full play to its innovation promotion effect.Private enterprises should be encouraged to collaborate in the field of common technology in order to avoid the innovation inhibition effect formed by horizontal competition.Making appropriate policies according to the enterprises' situations will also be conducive to the efficient allocation and comprehensive integration of innovative resources.
