Analysis on Statistical Measurement and Influence Factor of High Quality Economic Development——Taking the Yangtze River Delta as an Example
"High quality economic development"is the core requirements and strategic basis points of economic development at the present stage in our country.As the model area of high quality economic development,the high quality economic in Yangtze River delta area has been elevated to the top development goal of the national strategy.The paper takes the urban agglomeration in Yangtze River Delta as the study subject,and takes the 40 cities from 2010 to 2020 as sample observation area,and constructs the index system for high-quality regional economic development based on the scientific connotation of the new development concept.Then the Entropy TOPSIS method to measure the high economic development level of each city in Yangtze River Delta Area is applied comprehensively and the distribution characteristics are also analyzed.Finally,from the perspectives of economic scale,scientific and technological innovation,coordinated development,ecological environment,resource sharing and foreign trade opening,the influence mechanism on the level of high quality economic development is studied.The conclusions are as follows,the level of high quality economic development of the Yangtze River Delta urban agglomeration improved steadily from 2010-2020,and the gap between cities has been narrowed;the spatial pattern is mainly"strong in the east and weak in the west".The analysis of influence mechanism shows that the pollution of industrial enterprises has a significant inhibitory effect on the high quality development level of the Yangtze River Delta while other factors play a significantly role in promoting the high-quality development of the Yangtze River Delta.
