Study On The Measurement And Coupling Coordination Of Xinjiang Traffic Accessibility And Economic Linkages

Under the "Belt and Road" economic development initiative,Xinjiang,as the core area of the Silk Road economic belt,has achieved positive results in its economic strength.Under the influence of the strategy of powerful transportation country and the coordinated development of regional economy,Xinjiang,which is relatively backward in economic development and transportation conditions,must constantly improve and optimize the construction of transportation network within the region.Give full play to the role of transport infrastructure to promote economic development,so as to strengthen regional economic ties.Therefore,this paper takes all prefectures of Xinjiang as the research object,based on the relevant theory and research foundation,deeply explores the traffic accessibility and economic connection situation within Xinjiang region,and provides suggestions and references for the construction of Xinjiang traffic network and the coordinated development of economy.Traffic accessibility can reflect the development of regional traffic and is the basis of economic ties,and economic ties reflect the interaction between regions,which will have a certain impact on traffic accessibility.On the basis of the existing research,it is found that the traffic accessibility model and the economic connection model have room for improvement in the shortest travel time and the quality of urban development.Therefore,this paper modifies the weighted average travel time model and gravity model from two aspects: transit waiting time and urban comprehensive development level,which makes the measurement results of traffic accessibility and economic connection more accurate.This paper makes use of social network analysis to explore the structure of Xinjiang economic network.Finally,the degree of coordination between traffic accessibility and economic connection in all regions of Xinjiang is measured by using the coordination degree.research finding :(1)Traffic accessibility presents obvious central-peripheral structural characteristics.The areas with high accessibility level are concentrated in Urumqi metropolitan area and Bazhou area,and the phenomenon of north-south polarization is prominent.(2)The total amount of economic links shows the characteristics of Wuchang area as the center and south light north heavy,and mostly depends on railway transportation.(3)The economic connection between north and south Xinjiang is weak,and the central role of Urumqi and the sub-central role of Changji are obvious.(4)Economic connection network density is low,with obvious core-edge structure,can choose Urumqi,Bazhou,Turpan,Aksu and Kashi as the intermediary areas in the network.(5)The traffic accessibility-economic connection coupling coordination is in the unbalanced state,the north Xinjiang takes Wuchang as the center to the surrounding decline,the south Xinjiang takes Hotan as the center to the surrounding increase.Based on the above conclusions,this paper puts forward the suggestions of strengthening the construction of traffic network in southern Xinjiang,optimizing the structure of traffic network in Xinjiang,further enhancing the radiation capacity of Urumqi central city,giving full play to the intermediary role of Aksu and Bazhou.
