大西高铁对沿线地区产业发展的影响研究摘要随着我国经济社会的快速发展，交通运输业的发展趋势和经济社会快速发展的需求推动着我国交通运输网络的不断普及和完普。交通运输业作为我国国民经济发展中的重要力量为我国经济社会发展做出了巨大的贡献。铁路作为一个国家主要的运输方式、国民经济的大动脉，在人们的生产生活中发挥的作用越来越重要，其自身发展也不容小觑，其每一次变化都将对本国经济的发展产生关键的作用。从客运的角度来说，我们国家的铁路运能还是远远不足的。高铁的通达，不仅仅催动了沿线人流的互通，更为枢纽城市带来了勃勃生机。国家层面重视高铁基础设施的建设，加强了高速铁路‘四纵四横’为代表的铁路网建设，高速铁路建设力度仍然持续加大。截止到2013年末，我国高速铁路总营业里程达到11028公里，在建高铁规模1.2万公里，成为世界上高速铁路投产运营里程最长、在建规模最大的国家，中国的高速铁路初步成网。国家大力发展高铁客运，以缓解长期以来铁路人均里程不足的矛盾。而高铁的产业链非常长，对多个行业都有很强的拉动作用。从铁路建设拉动内需上看，在高速铁路建设期，在高铁上1元的投入，就会带动10元的投资。高速铁路的建成，为扩大内需提供了重要支撑。同时，高速铁路发展，有力地带动了沿线经济社会发展，带动了相关产业转型升级，带动了城市群的崛起。大同-西安客运专线是中国一条建设中的连接山西省大同市与陕西省西安市的高速铁路，是国家《中长期铁路网规划》的重要组成部分，这条铁路按照科学合理、以人为本的原则进行设计和规划，纵跨山西最具活力的经济带和城市群，对于拉动我国中西部产业结构调整和经济增长具有重要意义。为此，本文将从高速铁路建设与区域经济理论的分析入手，通过分析“大西高铁”对区域产业经济发展的影响机理，分析了其提升可达性的空间经济效益联系效应、对区域产业结构的优化效应及其对区域就业的增加效应，分析了大西高铁对区域一体化的促进作用、对区域相关产业的拉动作用、对区域产业集聚与扩散作用、对区域非产业性经济因素的作用及其对产业转型升级的作用，进而提出了发挥高铁优势，拉动沿线产业发展的策略，希望对我国高速铁路建设及区域协调发展具有一定的借鉴性意义。关键词：大西高铁，沿线地区，产业发展，辐射带动ABSTRACTWith the rapid development of China's economic and social,the trend of thedevelopment of transportation industry and the rapid development of economy andsociety demand driving the expansion and improvement of China's transportationnetwork.Transportation industry as an important force in the development of thenational economy made a great contribution to China's economic and socialdevelopment.Mode of transportation of the railway as a country mainly,the artery ofnational economy,in the role of more and more important in people's production andlife,do not underestimate their own development,its every change will produce keyrole on the development of its economy.From the point of view of passengertransport,railway transport capacity is far less than our country.High-speed access,suggesting not just along the flow of communication,more hub cities has broughtvitality.National level attaches great importance to the construction of high-speed railinfrastructure,strengthen the high speed railway represented been cross rail networkconstruction,high speed railway construction is still increasing.By the end of 2013,China has reached 11028 kilometers,the total mileage of high speed railway underconstruction 12000 km high-speed rail scale,become the world's longest high-speedrail operation mileage,the largest country in the construction scale,preliminary intoChina's high-speed rail network.Countries to develop high-speed railway passengertransportation,to ease the railway mileage per capita insufficient contradiction for along time.But the high-speed rail industry chain is very long,have very strong pullingeffect on multiple industries.Look from the railway construction of stimulatingdomestic demand,in the high-speed railway construction,on the high-speed rail 1yuan of investment,will drive the investment of 10 yuan.High-speed railway iscompleted,will provide an important support for expanding domestic demand.At thesame time,the high-speed railway development,effectively drive along the economicand social development,drive the related industrial transformation and upgrading,ledto the emergence of urban agglomeration.Datong xian construction of passengerdedicated line is a China connection in datong city,Shanxi Province and shaanxi
