摘　　要：根据山西省11个地级市间的高速公路平均行程时间、2021年各市的GDP和人口总量,运用引力模型计算各市的经济联系强度,研究各区域与周围区域间的相互影响和作用大小。结果发现:各市在对外经济联系总量方面有较大差距并表现出明显的等级特征;山西省区域经济联系强度存在差异,其中晋中地区经济联系密切,呈经济发展活跃态势;晋南和晋北地区域内部联系比较疏远,经济发展一般。各区域内和区域间经济联系方向主要沿高速公路构成并随之延伸,经济联系强度在道路距离的增长中不断缩小。As an important energy base and old industrial base in China,Shanxi province is a national pilot area for comprehensive reform of resource-based economy transformation,and plays an important role in promoting the reform and development of resource-based economy transformation.Based on the average travel time of highways between 11 prefecture-level cities in Shanxi Province,and the GDP and population of each city in 2021,the paper calculates the economic connection intensity of each city by using the gravity model and studies the interaction between different regions.The result indicates that the gap in the total amount of economic connection between cities is obvious,which presents clear characteristics of regional classifications;the intensity of regional economic connection in Shanxi province is different,namely,Jinzhong region is closely connected and relatively developed;the southern and northern Shanxi are relatively not closely connected and economic development are average;the economic connection within and between regions extends mainly along the highway and the intensity of economic connection is decreasing with the increase of distance.
