Research On Financial Agglomeration Promoting The High-Quality Development Of Yangtze River Delta Urban

From the 20th Party Congress in 2022 to the National Congress in 2023,high-quality development has become a series of key words for future development planning.The rapid economic and social progress in the past decades has made tremendous achievements,but the past crude and single development model and evaluation system can hardly fit the new development goals and development methods in the current context,and how to solve the uncoordinated,unbalanced and unsustainable problems in development has become the focus.As the core area of modern civilization and the frontline of reform and development,whether cities can effectively achieve high-quality development is the key to solving the above problems.As the "blood" of the modern economy,finance is at the core of the development of the social and economic industrial system,supporting and promoting the development of cities.The liquidity and profitability of financial factors often drive them to the most suitable areas for the flow of financial industry and eventually form clusters.Financial agglomeration is an inevitable phenomenon in the process of modern economic and social development.A comprehensive understanding of the impact of financial agglomeration on social development,and its scientific planning and utilization can provide strong support for high-quality urban development.At present,all major cities in China are paying more attention to financial agglomeration,with the aim of upgrading the number,structure and level of the financial services industry to promote the upgrading of industries and thus enhance the overall development of the city.Then it is necessary to analyze the way and strength of the financial industry development and agglomeration level on the high-quality development of the cities in the region.In this paper,we use the data of 41 cities in three provinces and one city in Yangtze River Delta from 2011 to 2019 as a research example to explore the influence of the financial industry in general and its sub-sectors on the level of quality development of cities.First,we summarize the theories and studies on financial agglomeration and high-quality development in the past,and summarize the mechanism of the former on the latter;then,we measure the agglomeration of financial industry and its sub-sectors in 41 cities in the Yangtze River Delta region,and measure and evaluate the high-quality development level of the above cities with the newly constructed evaluation system of high-quality urban development;finally,we construct a spatial econometric model to The actual effects and spatial effects of financial agglomeration in the Yangtze River Delta region on the level of high-quality urban development are analyzed,and the effects of the three major sub-sectors are further studied.The main conclusions are:(1)there is a significant financial agglomeration effect in the Yangtze River Delta region,and the degree of agglomeration gradually decreases from south to north,and the level of financial agglomeration varies greatly within the region;(2)the spatial correlation between financial agglomeration and high-quality development in the Yangtze River Delta region all increases first and then decreases,and the spatial distribution pattern of similar agglomeration is dominant;(3)the overall agglomeration of financial industry has a positive impact on the level of high-quality development in the region.(3)the overall concentration of financial industry has a positive impact on the level of high-quality development in the region,among which the concentration of banking industry and securities industry has a positive effect on the highquality development of the city,but the insurance industry is not significant;(4)the increase of the concentration of financial industry and securities industry in the region can promote the level of high-quality development in the surrounding areas,but the increase of the concentration of banking industry has a suppressive effect,and the insurance industry does not have a significant impact.The findings of this paper provide an effective supplement to the studies on financial agglomeration,urban high-quality development and the relationship between the two.By selecting a newer and more specific regional sample and trying to build a spatial model based on a more detailed sub-sector perspective,the spatial effects of the two are explored in the spatial dimension,which provides new exploration and evidence to study the impact of financial agglomeration on urban high-quality development and helps to further It has strong policy implications for the further development of financial agglomeration to promote the development of financial industry and enhance the level of high-quality urban development and eventually achieve regional synergistic development.
