Characteristics and Optimization Countermeasures for Hydrogen Industry Collaborative Innovation Networks in the Yangtze River Delta
Collaborative innovation is an effective way to make up for the lack of innovation resources in hydrogen energy industry around the world and improve the overall innovation level.Based on the patent data of hydrogen energy industry in Yangtze River Delta(YRD)from 2000 to 2021,this paper analyzes the characteristics of collaborative innovation in hydrogen energy industry in YRD in terms of cooperative R&D and technology transfer.It is found that:(1)the level of co-innovation in the hydrogen energy industry in YRD has been rising,with a higher level of co-innovation in hydrogen production,followed by hydrogen storage and use,and a lower level of co-innovation in hydrogen transportation and hydrogen refueling.(2)The level of enterprises'participation in co-innovation is much higher than that of colleges and universities,and scientific research institutes in the co-innovation network of the hydrogen industry in YRD.(3)The co-innovation network of the hydrogen industry in YRD shows a'core-edge'structure with economically developed cities as the core and economically less developed cities as the edge,as well as strong-strong co-operation and hierarchical characteristics.(4)The cooperative R&D network of the hydrogen energy industry in the Yangtze River Delta is highly agglomerative,showing a"zigzag"or diamond-shaped spatial pattern,while the distribution of the technology transfer network is wider,and the number of underdeveloped cities participating in technology transfer cooperation has increased significantly.Finally,this paper puts forward corresponding countermeasure suggestions,including promoting the whole chain of collaborative innovation,constructing an industry-university-research collaborative innovation system dominated by leading enterprises,strengthening cross-regional collaboration,and actively improving the support system,and so on.
