Comprehensive Evaluation and Dynamic Evolution of the Urban Entrepreneurial Ecosystem Construction Level in the Yellow River Basin
Taking 59 prefecture-level cities in the Yellow River basin as the research area,this paper measured the evaluation index of the entrepreneurial ecosystem of cities in the Yellow River Basin with the panel entropy weight method.It also analyzed the difference and spatial clustering characteristics of the construction of the ecosystem from 2012 to 2019 by using kernel density estimation and spatial autocorrelation The findings show that:(1)the construction level of urban entrepreneurial ecosystem in the Yellow River Basin and its three regions has been steadily improved,but the overall level of the river basin still remains low,presenting the regional characteristic of"downstream＞midstream＞upstream";(2)the absolute difference in the basin has been expanding,and the original gradient effect and multipolarization have been weakened;(3)the positive spatial autocorrelation is significant,and the level of urban entrepreneurial ecosystem construction in the Yellow River Basin cities is relatively differentiated,which exhibits a spatial distribution pattern featuring"high-high"agglomeration and"low-low"agglomeration as the main pattern,with"low-high"agglomeration and"high-low"agglomeration as secondary patterns.
