The Impact of Inclusive Finance on High-Quality Economic Development of the Yangtze River Delta in China

As a new service system of finance, inclusive finance emphasizes on better meeting the needs of people's livelihood at a reasonable and affordable cost. Inclusive finance can effectively solve the problems existing in the process of high-quality economic development by promoting regional coordinated development and narrowing the income gap between urban and rural areas. Firstly, this paper constructs the inclusive financial development level measurement index system and high-quality economic development measurement index system, uses these two index systems to measure the development of inclusive finance and high-quality economy of the Yangtze River Delta in China from 2010 to 2019, and then empirically analyzes the impact of Inclusive Finance on high-quality economic development in the Yangtze River Delta by using the panel threshold model. The results show that the inclusive financial development level and high-quality economic development level of cities under the jurisdiction of the Yangtze River Delta have increased steadily year by year, but the development level differentiation among different cities is obvious. Inclusive finance has a threshold effect on high-quality economic development. When the inclusive finance index is lower than 0.358, inclusive finance is not conducive to high-quality economic development. When the inclusive financial development index is between 0.358 and 0.522, inclusive finance promotes high-quality economic development, but the effect is weak. When the inclusive financial development index is greater than 0.522, inclusive finance can significantly promote high-quality economic development.
