| 中文摘要:使用Dagum基尼系数、描述性统计等方法，研究中国五大城市群R&D资本存量差异与分布特征。结果显示：中国五大城市群R&D资本存量差异大，但呈缓慢下降趋势，差异主要来源于不同城市群之间；不同城市群内部以及不同城市群之间R&D资本存量差异大小及其演进趋势具有显著差异。R&D资本存量向五大城市群特别是长三角城市群以及粤港澳大湾区集聚。五大城市群内部R&D资本存量分布特点及演进趋势各不相同。鉴于此，揭示了中国五大城市群R&D资本存量差异与分布特征，从而为城市创新发展战略及政策制定提供理论依据。 |

| Abstract:Dagum Gini coefficient and descriptive statistics were used to study the differences and distribution characteristics of R&D capital stock in China’s five major city clusters. The results show that: (1) the differences of R&D capital stock in China’s five major city clusters are large, but show a slow downward trend, and the differences mainly come from different city clusters. There are significant differences in the size and evolution trend of R&D capital stock within and between different city clusters. (2) R&D capital stock is concentrated in the five major city clusters, especially the Yangtze River Delta and the Guangdong-Hong Kong-Macao Greater Bay Area. The distribution characteristics and evolution trend of R&D capital stock in the five major city clusters are different. The paper reveals the differences and distribution characteristics of R&D capital stock in China’s five major city clusters, and provides theoretical basis for urban innovation development strategy and policy formulation. |
