In China, government policy support is an important driving force for promoting the development of incubators. The rationality and effectiveness of policies are the key to guiding the development of incubators in the early stage. Research on incubator policies can help clarify the support methods and priorities of policies. This paper employs the bibliometrics method and follows a procedure of keyword extraction, co-wording and cluster analysis to analyze the system and structural characteristics of incubator policy. The research shows that the overall policy of incubator in Guangdong is mainly composed of four types of policies: Land support, taxation, financial support, investment and financing policies. The financial support is at the core of the incubator policy system and policy is mainly focused on the front chain of incubator development, encouraging the development of the number of incubators while at the same time the support for talents is weak and the effect of policy implementation is not supervised. On this basis, combined with the reality of the development of incubators, this paper puts forward opinions and suggestions for the formulation and adjustment of the incubator policy.
