Study on the spatial and temporal evolution of technological innovation capability of industrial enterprises above the scale in Yangtze River Economic Zone

Abstract

This paper employs exploratory spatial data analysis to examine the global and local autocorrelation of the spatial clustering of technological innovation capabilities of industrial enterprises above the scale in 11 provinces and cities in the Yangtze River Economic Belt, and to investigate its spatio-temporal evolution characteristics. It is found that (1) the technological innovation capability of industrial enterprises above the scale in the Yangtze River Economic Belt is not randomly distributed, but shows a significant clustering trend; (2) the positive spatial correlation becomes gradually weaker from 2011 and 2020 Moran's I index scatter plots, most of the cities in this 10-year time change are located in the first and third quadrants, indicating that the technological innovation capacity of enterprises in these cities has a high positive correlation in geographic space, so it is a general trend to strengthen the inter-regional cooperation capacity.
