晋陕豫黄河金三角示范区的区域经济发展——从经济联系与中心职能强度分析

On the Regional Economic Development of the Golden Triangle Demonstration Area of the Yellow River in Shanxi,Shaanxi and Henan Province from the Economic Connection and the Function Intensity of the Center

运用主成分分析、修正引力模型和中心职能强度模型实证分析晋陕豫黄河金三角合作示范区四市的经济联系强度以及各城市在区域内的引领作用大小,发现基于主成分分析的城市综合实力中三门峡市目前的综合实力最高,渭南市紧随其后;从省际城市间的经济联系强度来看,渭南市与三门峡市两市间的经济联系强度最大,但也难掩省际“边界效应”影响,因为同属山西省的运城和临汾两市的经济联系强度最大;从各城市在区域内的中心职能强度来看,渭南市因其地理区位优势、良好的经济发展均衡度以及人力资源禀赋等有利因素加持,渭南市在区域内的发展潜力最大,中心引领作用将得到进一步显现。

This paper used principal component analysis,revised gravity model and central function intensity model to empirically analyze the economic connection strength of the four cities in the Golden Triangle Demonstration Area of Shanxi-Shanxi-Henan Yellow River and the leading role of each city in the region.The following conclusions were drawn:based on principal component analysis,Sanmenxia city has the highest comprehensive strength,followed by Weinan city.In terms of the strength of economic ties between provincial cities,Weinan city and Sanmenxia city have the greatest economic ties,However,it is also difficult to conceal the influence of“boundary effect”between provinces,because the economic links between Yuncheng city and Linfen city in Shanxi province were the strongest.In terms of the intensity of the central functions of cities in the region,Weinan city is supported by favorable factors such as geographical location,good balance of economic development and human resource endowment.Weinan has tremendous potential for development in the region,and its central leading role will be further revealed.Finally,the problems existing in the development of Jin-shan-Yu Yellow River Golden Triangle Cooperation Demonstration Zone were analyzed,and the corresponding countermeasures and suggestions were put forward.
