Coordinated Development of Beijing-Tianjin-Hebei City Group from the Perspective of Regional Economics - Comparative Analysis Based on the Gravity Model

摘要

Promoting the coordinated development of Beijing-Tianjin-Hebei, adjusting the regional economic structure and spatial structure, and promoting the construction of Hebei Xiong'an New District and Beijing's urban sub-centers are one of China's three major national strategies. From the perspective of regional economics, this paper quotes a gravity model, and analyzes the strength of the economic connection between the Beijing-Tianjin-Hebei urban agglomeration and the Yangtze River Delta city agglomeration. The cluster is obviously weaker than the Yangtze River Delta city cluster. To develop the Beijing-Tianjin-Hebei urban agglomeration into a world-class urban agglomeration, it is necessary to take advantage of the opportunity to build the Xiong'an New District, to defuse Beijing's non-capital functions, solve "big city diseases", improve the functions of surrounding cities, and build a good-level, close-knit economic cluster pattern.
