An Empirical Study on the Impact of Service Industry Agglomeration on High Quality Economic Development in Beijing, Tianjin and Hebei

This paper uses the panel data of 13 cities in Beijing-Tianjin-Hebei region from 2012 to 2020 and uses TOPSIS to construct the economic quality development index in four aspects: scientific innovation, economic quality, green ecology and life security, followed by the calculation of the service industry aggregation index of each city using the locational entropy method. Finally, the regression is fitted by panel Tobit model, and the results show that the spatial distribution pattern of service industry aggregation in the region shows Beijing and Tianjin as the core, but the degree of service industry aggregation in Beijing and Tianjin as the core of aggregation gradually decreases in the long term, while the degree of aggregation in other prefecture-level cities gradually increases. More importantly, the service industry agglomeration in Beijing-Tianjin-Hebei region has a significant positive contribution to high-quality economic development in the long run.
