Measuring integrative level and analysis of radiative capacity in China's urban agglomerations
As a spatial aggregator leading regional economic development,the study of the level of internal integration and external radiation capacity of urban agglomerations is of great significance to the high-quality development of urban agglomerations and the coordinated development of the region.This paper uses the data of 284 prefecture-level and above cities in China from 2006-2019 to construct CD production functions embedded in endogenous spatio-temporal weight matrices to measure the integrative level and the radiative capacity of the urban agglomerations,and further analyses the relationship between the two.The study finds that:(1)Among the endogenous spatio-temporal weight matrices of MORAN,GEARY and GO indices,the CD production function based on the matrix of MORAN index is the most optimal one,which is able to accurately decompose the spatial spillover effects of internal and external factors.(2)In terms of temporal development,there are fewer urban agglomerations in areas with high values of integrative level and radiative capacity,while there are more urban agglomerations in areas with low values,and the integrative level and radiative capacity of the urban agglomerations as a whole are on the low side,but there is an upward trend in recent years.(3)In terms of spatial evolution,the integrative level and radiative capacity of urban agglomerations in the eastern region are stronger,while those of the western region are weaker.The Yangtze River Delta urban agglomeration,the Pearl River Delta urban agglomeration and the Beijing-Tianjin-Hebei urban agglomeration are in the top three,while the Lanzhou-Xining urban agglomeration,the Ningxia urban agglomeration along the Yellow River and the Tianshan North Slope urban agglomeration are in the back of the list.(4)The integration of urban agglomerations can significantly enhance their radiation capacity,and the heterogeneity is obvious.Meanwhile,the FDI,the informatization and the transport infrastructure have a positive effect on the radiative capacity,while the financial development has a negative effect.
