Research on the Influence of Provincial Capital Primacy on the High-Quality Development of Regional Economies:Based on the Decomposition Analysis Perspective of Spatial Spillover Effect
The primacy of provincial capitals is closely related to the high-quality development of the re-gional economy,and the high-quality development of the provincial regional economy can be achieved by im-proving the leading and radiating power of provincial capitals.Using the panel data of 26 provinces and cities in China from 2008 to 2021,the impact of the primacy of provincial capitals on the high-quality development of regional economy is examined.By setting up a two-way fixed effects model and a spatial panel Durbin model,we analyze the growth and spatial spillovers of the regional economy under the influence of provincial capital pri-macy.The study finds that there is a significant non-linear correlation between provincial capital primacy and regional economic development.Specifically,the relationship shows an inverted U-shape in the eastern,cen-tral and western regions,while the relationship is linear in the northeastern region.The mechanism test shows that the primacy of provincial capitals can promote the upgrading of industrial structure,and then promote the high-quality development of the regional economy.In addition,the spatial test shows the significant spatial de-pendence and positive spatial spillover effect of the primacy of provincial capitals on the regional economic de-velopment of neighboring regions.Therefore,it is recommended to strengthen the primacy of capital cities and actively upgrade the industrial structure in the light of the actual situation of each province,so as to promote the synergetic development of the province and neighboring provinces,and achieve the high-quality development of the regional economy.
