Abstract
This paper uses spatial panel VAR model to study the spatial spillover of the collaborative innovation of Science and technology in the Pearl River Delta urban agglomeration from 2010 to 2018. The empirical results show that a positive shock on the collaborative innovation of Science and technology of a city in the Pearl River Delta urban agglomeration will spread to other cities in the Pearl River Delta urban agglomeration, and will have a positive impact on the collaborative innovation of Science and technology and R & D input variables of other cities in the second period; A positive shock on the R & D input of a city will make the collaborative innovation of Science and technology and R & D input variables of the city and other cities have a positive impact in the second period; the collaborative innovation of Science and technology and R & D input variables have positive external effects in the Pearl River Delta urban agglomeration. Finally, some suggestions are put forward.
