Evaluation of China's Inter-Provincial Scientific and Technological Innovation Capability and Spatiotemporal Evolution
This paper constructs an evaluation index system of scientific and technological innovation capability from three aspects:innovation input,innovation output,and innovation environment,as well as two dimensions of innovation scale and innovation level.The entropy-weighted Topsis method,Dagum Gini coefficient,kernel density and ESDA were used to explore the spatiotemporal evolution characteristics of China's inter-provincial sci-entific and technological innovation capability from 2012 to 2021.The results show that:(1)the overall difference of China's scientific and technological innovation capability is expanding,mainly due to the differences in the northern region;(2)The polarization of scientific and technological innovation development in the whole country and the southern region is weakened,and the development of scientific and technological innovation in the north-ern region is multipolarized;(3)The spatial agglomeration effect of China's inter-provincial scientific and techno-logical innovation capability has been increasing since 2019.
