Logistics industry as an important part of the future of the national economy,for the adjustment of industrial structure,change the mode of economic development and enhance the competitiveness of the national economy plays an important role.Promoting the development of modern logistics is transportation the facing daunting task of new era,for this,The country issued a series of preferential safeguards,while Chong qing also of the relevant planning the broad framework of the preparation of the next Five-Year Plan in to promote modern logistics industry rapid development.Thus,the Chongqing logistics and transport development needs urgent and broad prospects.Thus,the Chongqing logistics and transport development needs urgent and broad prospects.For Chongqing automotive logistics,especially automobile enterprises in Chongqing Chongqing Chang an Automobile brings logistics channel construction and an opportunity to implement.As of the first half of 2014,Chang an Automobile production accounts output of the total automobile in Chongqing for 65%.However,Chang an automobile and parts transport channel by Chongqing(especially downtown)on sections of cargo and line policy limited of,resulting in the existing logistics solutions can not meet the needs of Chang an Automobile Industry Development.Thus forming meet future stream channel(especially internal logistics channel)is Chongqing Chang an Automobile demand urgent problem.Based on past almanac data,such as Chang an Automobile main years passenger traffic in trends,passenger YEARS turnover trends,and trends YEARS port throughput deduced future passenger and freight traffic.Then this paper elaborated Chongqing Chang an Logistics channel vehicle and parts logistics channel status quo.Through the important logistics channel traffic survey,summed up Chang an Automobile logistics channel has road limit line,road limit,road freight capacity shortage,congestion overpass,crossing unreasonable,transport bypass and several other issues.Then this paper introduced the production and sales situation and the distribution and planning stage of Chang an Automobile automobile industry and logistics industry.We focus on the problem from the above points are analyzed,such as Chongqing Chang an Automobile logistics channel demand analysis,internal and external logistics channel convergence nodes and vehicle passage needs analysis,highway vehicle logistics distribution center node analysis,water iron automobile logistics node analysis,vehicle logistics channel needs analysis,parts logistics channel needs analysis,factors associated logistics channel analysis,correlation analysis factors which also includes logistics corridor for road transport,the relevant policy,trade housing,combined with logistics channel needs analysis and Impact factor comprehensive evaluation.Through methods of investigation,analysis,summary and evaluation,selected transport routes channel and drawn two logistics of transport solutions.Finally,the development of Chang an Automobile logistics channel some suggestions,including planning grasp the opportunity and strive to incorporate the program,emphasis road transport regulations,to break the policy bottleneck to seize key bases,access to land and other central points,hope to Chang an Automobile optimization of logistics channels play some help.
