Research Methods: Such as exploratory data analysis, standard deviation ellipse analysis, kernel density estimation and Markov chain method are used to reveal the spatial distribution and evolution characteristics; Dagum Gini coefficient is used to analyze the spatial differences and sources of innovative development; The coefficient of variation and spatial Durbin model are used to test the convergence of innovative development. Research Findings: The shift of gravity center presents a process from east to South and then to southwest, the neighborhood innovation environment directly affects the spatial distribution pattern of urban innovative development in the Yellow River Basin, and there is a certain path dependence on innovative development, but the whole, Cities with a lower level of innovative development can achieve a leap-forward development in three to five years, and the spatial dependence decreases with the passage of time. In the middle and lower reaches, innovative development presents a periodic characteristic of “polarization→convergence”, while in the upper reaches, innovative development presents an evolutionary trend of “polarization→convergence”. The overall difference of innovative development in the Yellow River Basin as well as its internal difference in the middle and lower reaches showed an “M” pattern of upward sloping right, and the internal difference showed a pattern of “middle reaches>upper reaches>lower reaches” after 2009. The internal innovative development difference in the middle reaches is the epitome of the overall innovative development difference. The difference between the upper, middle and lower reaches of innovative development is the main source of the overall difference, and presents an inverted u-shaped change. Only the upper reaches of the basin have the characteristics of σ convergence, while conditional β and absolute β converge in the whole basin and the upper, middle and lower reaches of the basin. The convergence rate shows the characteristics of “upper reaches>middle reaches>lower reaches”, which is different in stages. Research Innovations: To reveal the temporal and spatial distribution characteristics of innovative development in the Yellow River Basin, to study the sources and contributions of innovative development differences, and to test its convergence characteristics. Research Value: It is of great significance to reduce the difference of innovative development and realize collaborative innovation and high-quality development in the Yellow River Basin. | | 查看全文 |
