Evolution of global innovation network and its proximity mechanism in synthetic industry:A case study of energy conservation and environmental protection industry
In the era of the knowledge economy,the primary emphasis of technological innovation is shifting towards networked,open,and multi-agent interactive collaborative innovation.However,there are numerous debates surrounding network structure and performance,primarily stemming from the neglect of the crucial role of the knowledge base.Currently,the research focus on the knowledge base of industries is to understand the relationship between analytical knowledge base,synthetic knowledge base,and regional innovation systems.Scholars have explored the multi-scale spatial patterns in analytical industries.But the attention to the innovation networks of synthetic industries is limited to smaller spatial scales,which has certain limitations.With the expansion of enterprise scale and the rise of multinational company platforms,as well as the need to overcome the negative effects of excessive localization,the characteristics of cross-border innovation networks in synthetic industries have become increasingly prominent.Nevertheless,there is limited research conducted from a global perspective on long-term time series analysis of innovation networks in synthetic industries.Because of it,taking the energy conservation and environmental protection industry as a case of synthetic industry,and industrial innovation network among 193 countries from 2000 to 2020 was constructed.We studied the topological structure,spatial pattern evolution characteristics and its proximity mechanism in synthetic industry.The results show that:Firstly,the scale of the global innovation network for energy conservation and environmental protection industry continues to expand,but the development level is low.The technical cooperation between countries has the characteristics of preferential attachment,which shows a core-edge structure of strong core and radial.The disequilibrium characteristics of the network are obvious but have a reduced trend.Secondly,in the development process of global cooperation in energy conservation and environmental protection industry,a clear regionalization trend is evident,with a stable spatial orientation.This situation has led to the formation of multiple clusters of industry and technology cooperation that continuously diverge and integrate.Thirdly,the promoting effects of geographic proximity,technological proximity,and institutional proximity on cross-border cooperation in energy conservation and environmental protection industry continue to strengthen.The positive influence of social proximity remains at a high level throughout the three stages,while the impact of cultural proximity remains insignificant.Lastly,the relations between geographical proximity and technological/institutional proximity are complementary.The interaction effect between geographical proximity and cultural proximity is not significant.Geographical proximity and institutional proximity have significant complementary effects only in the third stage.
