效率视角下"一带一路"沿线国家创新影响力研究

从效率差异视角构建国家创新影响力评价方法,揭示“一带一路”沿线国家创新要素流动倾向性以促进交流合作。运用DEA模型测算各国创新效率,根据DEA原理识别国家间的认可关系,构建创新网络并用节点特征向量中心度表示各国创新影响力,分析创新影响力类型、创新网络特征及创新投入冗余率与产出不足率。结果发现,各国创新效率存在显著差距;各国分别处于创新网络中心、核心和边缘位置,国家创新影响力依次递减;按照创新要素相对强度,沿线国家可分为6种创新类型;最后,提出沿线国家间开展创新交流与合作的必要性和途径。

Research on Innovation Influence of Countries along "One Belt and One Road" from the Perspective of Efficiency

The evaluation method of national innovation influence is established from the perspective of efficiency difference, and the flowing tendency of innovation factor among countries along "One Belt and One Road" is revealed so as to promote exchanges and cooperation. The innovation efficiency of each country is calculate using DEA model, and the endorsing relationship among countries is identified according to DEA principle. Furthermore, the innovation networks are constructed and the innovation influence of each country is expressed by the eigenvector centrality of nodes, and the innovation influence type, the innovation network characteristics, the innovation input redundancy rate and the output deficiency rate are analyzed. The study show that there is a significant gap between countries in innovation efficiency; countries are distributed at the center, the core and the edge of the innovation network, whereas the influence of national innovation decreases in turn; According to the relative intensity of innovation elements, countries along the belt and road can be divided into 6 types of innovation. The necessity and ways of innovation exchange and cooperation between countries along the route are proposed.
