A Study On The Panel Threshold Effect Of Financial Agglomeration In The Yellow River Basin On Ecological Efficiency

On September 18,2019,General Secretary Xi Jinping delivered an important speech at the symposium on ecological protection and high-quality development of the Yellow River Basin.For the first time,he raised the issue of ecological environmental protection and high-quality economic development in the Yellow River Basin at the national strategic level.This provides unprecedented development opportunities for the development of the provinces along the Yellow River Basin and new guidance for the construction of the Yellow River Basin.On the road of sustainable economic development and ecological civilization construction,nine provinces in the Yellow River Basin are facing increasingly severe ecological and environmental challenges.The effective protection of the Yellow River Basin and high-quality development are of great significance to China 's ecological health and sustainable economic and social development.On the one hand,the Yellow River Basin is an important ecological barrier in China.On the other hand,the Yellow River Basin is an important area for poverty alleviation.The ecology of the Yellow River Basin and the realization of sustainable economic development in the Yellow River Basin are the only way to realize the great rejuvenation of the Chinese nation.Therefore,studying the ecological protection of the Yellow River Basin has certain practical significance and practical value.To promote the high-quality development of the Yellow River Basin and protect the ecological environment of the Yellow River Basin,it is necessary to measure the current scientific development level and environmental status of the Yellow River Basin.In recent years,the phenomenon of financial agglomeration has gradually emerged in China.Regional financial centers have vigorously developed under the national strategic direction of national central cities driving regional coordinated development.Research on financial agglomeration has also become a major research direction in academia;financial agglomeration With the improvement of industrial agglomeration,an agglomeration phenomenon can occur,which can effectively adjust the allocation of resources and thus affect the regional ecological efficiency.Therefore,this paper chooses to study the relationship between the ecological efficiency and financial agglomeration of all provinces along the Yellow River Basin.Using empirical methods such as entropy weight method,data enveloping super-efficiency model,panel threshold model,etc.,the eco-efficiency level and financial agglomeration level of nine provinces along the Yellow River Basin were measured,and the nine data along the Yellow River Basin were further studied through the calculated data Whether the province's economic development level and financial agglomeration level can improve its ecological efficiency level.The research ideas of this article are as follows: First,we will introduce the definition of financial agglomeration,the connotation of economic development,and the concept of ecological efficiency.Then analyze the interaction mechanism among the three provinces and regions along the Yellow River Basin;secondly,when analyzing the current status of financial agglomeration,construct the evaluation systems of nine provinces in the Yellow River Basin from 2010 to 2017 respectively.Specifically,this evaluation system is constructed from the four perspectives of banking,insurance,securities,and overall financial scale,and uses the entropy weight method to measure the level of financial agglomeration in the Yellow River Basin;in terms of ecological efficiency,it is based on natural resources.The investment and the burden of economic development on the ecological environment both measured the ecological efficiency levels of nine provinces through data envelopment DEA.After further obtaining the comprehensive indicators of financial agglomeration,economic development and ecological efficiency,the panel threshold model is used to test the thresholds of the measured values of financial agglomeration,economic development and ecological efficiency;and the further analysis of its impact relationship.The research shows that there is a threshold effect on the ecological efficiency of financial agglomeration and economic growth in the Yellow River Basin.Both financial agglomeration and economic growth can improve the ecological efficiency,and there is a double threshold effect on the ecological efficiency.Among them,the financial agglomeration has a U-shaped effect on the ecological efficiency.Double threshold effect.At this stage,financial agglomeration has an inhibitory effect on ecological efficiency.On the other hand,the development of primary and secondary industries,permanent population and the use of chemical fertilizers at this stage cannot effectively affect ecological efficiency.
