摘　　要：以2016—2020年长三角城市群的26个城市为例,对长三角城市群整体的对外开放度、经济极化程度以及各个城市对区域经济极化效应的贡献度进行测算,运用单位根检验、空间自相关等计量经济模型分析对外开放度对城市和区域经济极化影响的协同效应,探究对外开放度的变化对城市和区域的经济极化的影响。结论认为:长三角城市群区域对外开放度和经济极化程度存在长期稳定的均衡关系,但是区域的对外开放度对经济极化效应的影响缺乏稳定的一致水平;长三角城市群的对外开放度与其经济极化效应之间存在协整关系和正向相关关系,即随着城市对外开放度的提高,其经济极化效应也在提高。格兰杰因果检验表明:长三角城市群区域层次的对外开放度不是经济极化效应的格兰杰原因,而经济极化效应是对外开放度的格兰杰原因;城市层次的对外开放度是经济极化贡献度的格兰杰原因,而经济极化贡献度不是对外开放度的格兰杰原因。Taking 26 cities in the Yangtze River Delta urban agglomeration from 2016 to 2020 as examples,the overall degree of openness and economic polarization of the Yangtze River Delta urban agglomeration,as well as the contribution degree of each city to the regional economic polarization effect,were measured.The unit root test,spatial autocorrelation and other econometric models were used to analyze the synergistic effect of openness on urban and regional economic polarization.This paper explores the influence of the change of openness to the outside world on the economic polarization of cities and regions,and concludes that there is a long term stable equilibrium relationship between the regional openness to the outside world and the degree of economic polarization in the Yangtze River Delta urban agglomeration,but the influence of regional openness to the outside world on the economic polarization effect lacks a stable consistent level.There is a co integration relationship and a positive correlation between the opening degree of cities in the Yangtze River Delta and their economic polarization effect;that is,as the opening degree of cities increases,so does the economic polarization effect.Granger causality test shows that regional level openness of Yangtze River Delta urban agglomeration is not the Granger cause of the economic polarization effect,but the economic polarization effect is the Granger cause of openness.The city level of openness to the outside world is the Granger cause of economic polarization contribution,but the city’s economic polarization contribution is not the Granger cause of the opening to the outside world.
