Abstract:Based on the information of patent metrics of cooperative application by Guangzhou and the provinces along The Belt and Road, SPSS and social network analysis, the time sequence, technology development, technical field, regional spatial distribution, collaborative subject and social network of the coordinated science and technology innovation between the pivot city and the provinces along The Belt and Road are analyzed. The study found that: (1) The coordinated science and technology innovation behaviors between the Pivot city and the provinces along The Bel and Road have geographical proximity, economic proximity, organizational proximity and technological proximity. (2) The coordinated science and technology innovation network of the Pivot city and the provinces along the "one belt and one road" have the characteristics of "small world". (3) the Pivot city and the provinces along the "one belt and one road" should combine their own advantages, appropriately increase funds and personnel input for research and test development, improve the network post and telecommunications facilities, and optimize the conditions for collaborative science and technology innovation. (4) Collaborative entities should combine the characteristics of proximity, promote the continuous growth, renewal and development of core technology and emerging technology by enhancing collaborative technological innovation, enhancing the collaboration, absorption and transformation of technology.
