Abstract In order to promote the coordinated development of China's regional economy and improve the effectiveness of government innovation funding, based on the panel data of 882 strategic emerging listed companies in 30 provinces and cities in China from 2012 to 2019, the Theil index, exploratory spatial data analysis (ESDA) and other methods are used to investigate The temporal and spatial evolution characteristics of technological innovation investment of China's strategic emerging enterprises, through the construction of a spatial panel model, analyze the key factors that affect the technological innovation investment of Chinese strategic emerging enterprises.The results show that: ①the overall technological innovation investment of enterprises shows a fluctuating upward trend, with the highest investment intensity in eastern; ②the overall technological innovation investment of enterprises tends to be equalized, and there are largely internal differences among the three major regions of East, Central and West; ③the “central-peripheral” characteristics of enterprise technological innovation investment are obvious. The “central” provinces are mostly located in the eastern and central regions, and the “peripheral” provinces are mostly located in the western inland areas. The spatial correlation model is mainly H-H and L-L; ④government innovation funding has a significant role in promoting technological innovation investment of enterprises, and technological innovation investment of enterprises has a significant negative spatial spillover effect; ⑤Government innovation funding has a more significant role in promoting technological innovation investment in high-innovation funded enterprises in the eastern region, and the negative spatial spillover effect of technological innovation investment in high-innovation funded enterprises is more significant.
