Abstract:Based on the metrical information of Guangdong-Hong Kong-Macau Greater Bay Area's cooperative patent application, this paper probes into the current situation characteristics of collaborative technological innovation in 11 cities of this area, such as timing, technical field, regional spatial distribution, cooperative subject and so on and predicts the trend, with the help of spss statistical analysis method. The findings are as follows: (1) The cooperate technology innovation in the area is increasing continuously and changing from quantity-speed type to quality-benefit type gradually. (2) The development of collaborative technology innovation in the area is unbalanced with the characteristics of territorial proximity.(3) There are some differences in the core technology of cooperate technology innovation among cities, and the spatial agglomeration effect of emerging core technology becomes more and more obvious.(4) All of the cities are supposed to promote the continuous growth, renewal and development of core and emerging technologies, by combining the advantages of technological innovation and enhancing the collaboration, absorption and transformation of innovative technology research and development.
