An Evaluation of the Coupling Coordination of Technological Innovation System in China’s Marine Biopharmaceutical Industry

The marine biopharmaceutical industry (MBI) has been considered as an important part of the blue economy. The high-quality development of this industry depends on the high-level coordinated development of technological innovation system (TIS). In the present study, the coupling mechanism of industrial innovation input subsystem and innovation output subsystem was analyzed for the first time. On this basis, the development level and coupling coordination level of TIS in China’s MBI during 2008–2018 were empirically evaluated with the capacity coupling coordination model. Then, the obstacle factors were diagnosed and recognized with the obstacle model. The results showed that the innovation input index fluctuated at a low level in China’s MBI. The innovation output index has basically maintained a growth trend, whereas the quality of development was not high. Although the coupling coordination level of TIS showed a positive change as mild disordered → primary coordinated → well-coordinated, the development type of innovation system has changed from the lagging output of innovation into the lagging input of innovation. Insufficient input of innovation factors remained the main obstacle to the improvement of coordination level. Based on the above analysis, suggestions were put forward from the perspectives of policy and fund guarantees to improve the coupling coordination level in China’s MBI.
