Threshold regression analysis is used to analyze the impact of computer software and information technology service industry agglomeration on manufacturing competitiveness

Based on the panel data of computer software and information technology service industry agglomeration in 28 provinces and cities in China from 2015 to 2019, this paper calculates the agglomeration and other indicators, and uses the threshold effect model to study the impact of computer software and information technology service industry agglomeration on manufacturing competitiveness. The results show that when agglomeration is taken as the threshold variable, there is a significant single threshold for manufacturing competitiveness. The degree of competition and the investment of per capita GDP can significantly promote the improvement of manufacturing competitiveness. The impact of regional economy and openness on manufacturing competitiveness is contrary, and the interaction needs to be improved.
