Study On The Influence Of High-speed Railways On Regional Development

The relationship between transport and regional development has been an important practical and theoretical issue, which is also one of the important issues attentioned by economics, geography academics and government. With the increasing development and construction of high-speed rail depth, the need becomes more and more obvious for studying on the influence of high-speed railways on regional development. How to scientifically and systematically to objective evaluation of high-speed rail on the influence of regional economic development is the geography, transportation planning, economics and other fields face an important problem. Taking into account the accessibility plays an important role in regional economic development and spatial structure, the paper studies the spatial accessibility as the effects of high-speed rail entry point for regional impact.In support of GIS technology, the evaluation of accessibility was conducted with three indicators,i.e. daily accessibility, potential model,and weighted average time.After the evaluation,differences between accessibility patterns with scenarios and with and without high-speed railways were analyzed,Changes in urban hinterlands of the center cities were also calculated with field intensity model, discussing the influences of the high-speed railways on center cities'accessibility and urban hinterland. Finally, based on research findings, this article attempts to propose classification of coping strategies to guide the local government from the transportation, industrial, spatial structure and other aspects.The main conclusions are as follows:the overall accessibility of spatial pattern in North Anhui no major changes due to the high speed railway. accessibility ptimum channel region are concentrated along the Beijing-Shanghai, high-speed railways would expand the isochronous rings of cities in North Anhui,Compared with the internal accessibility, improvements in external accessibility more prominent. Weighted time value of each city greatly reduced the potential value of the location advantage is generally improved, and outside the region from the three central cities of friction are very heavily weakened by commuting time significantly shortened. Hefei, Nanjing, Xuzhou outside the central cities of these three to-day north Anhui has expanded significantly the scope of the exchange cycle, up to a substantial increase in area. Sites along the high-speed railways became the biggest beneficiaries of time convergence, while the outer edge of north Anhui Northwest of accessibility and other variables was low, benefiting small. Gini coefficient of determination showed that high-speed rail in Northern accessibility expanded regional differences and differences within cities, high Rail to bring more development opportunities along the city, but also expand the reach of the gap in some areas, accessibility of the iron from the high-income areas less likely to fall into the "marginalized" in the non-equilibrium of the overall trend still exists" excellent in better "phenomenon.In considering only the pattern of "7" central cities of north Anhui, high-speed railways in the heart of expanding the hinterland of Bengbu, has little effect on other cities in the hinterland. So high-speed railways can not shaken all over the city in north Anhui hinterland of the overall spatial pattern.When taking into account the urban pattern of "7+3" central cities, large cities outside north Anhui rely on high-speed rail network quickly expanded its hinterland, in north Anhui cities, outside the center in Northern cities and the hinterland has become overlapping, Anhui Multi-level cities around the hinterland of North embedded in the hinterland outside the high-grade central city, the hinterland is further squeezed, an area generally reduced, the overall spatial pattern of urban hinterland of north Anhui, thus greatly affected.
