Impact of Innovation Factor Flow on the High-quality Development of Regional Economy in the Yangtze River Delta

He economic and social development of the Yangtze River Delta has always been in the forefront of the country. The Yangtze River Delta, which is rich in science and education resources, is one of the regions with the strongest innovation ability in China, and innovation is the driving force driving high-quality economic development. In order to explore the impact of innovation factor flow on the high-quality development of regional economy in the Yangtze River Delta, based on the panel data of 26 prefecture level cities in the Yangtze River Delta from 2010 to 2019, this paper selects the indicators of high-quality economic development level, evaluates the high-quality economic development level of each city with entropy method, and calculates the flow of innovation factors of each city with gravity model. Using the spatial autocorrelation model, this paper empirically analyzes the effect of innovation factor flow on the high-quality development of regional economy in the Yangtze River Delta. The empirical results show that there is a positive spatial correlation between the high-quality economic development level of the Yangtze River Delta, that is, the improvement of the high-quality economic development level of the city will drive the improvement of the high-quality economic development level of adjacent cities. Innovation personnel flow and innovation capital flow will affect the improvement of high-quality development level of regional economy, and the impact direction is significantly positive. The research results have certain enlightenment for correctly guiding the rational flow of innovation factors among the Yangtze River Delta regions, promoting the re combination of innovation factor resources and traditional factor resources in the region, and optimizing the allocation of innovation factor resources in the region, so as to improve the high-quality development level of regional economy
