| The industrialization and urbanization is accelerating with the development of economy and the progress of technology in our country. we are increasely investing into the infrastructure at the same time.especially in recent years the network of rail transportation is gradually improved under the development of high-speed railway in China, Many less developed cities will also be included in the transportation system, which will make an opportunity for the increasingly frequent communication between big cities and small and medium-sized cities. China’s high-speed railway construction greatly shortens the distance of space and time between cities. Many less developed cities are constructing largely, which hope to be able to user this opportunity to promote the overall level of economic development of the city. The less developed cities treat the construction along the high-speed railway station as foreign propaganda image window. High railway is a kind of effective method for solving the problem of heavy passenger transport of high speed railway the, to promote urban development and the regional economic growth and promote the evolution of spatial structure. High-speed railway can not only significantly change the city’s traffic location, industrial structure and spatial layout, but also can greatly enhance the competitiveness of the city, a distinctive urban economic development road can be made If the cities can accurate position their role in the economic development, give full consideration to its own resources and advantages of economic development, change the original mode of city development, make traffic combined with the development of the city power, properly adjust and come up with a strategy of city development, differ in development finance, hotels, guesthouses and other high-end industries, adjust measures to local conditions, play their own specialized division of labor. High-speed railway could be used to solve two different accessibility problems. In the first case, where a point to point link is dominant, they are a potential substitute for air travelling. In the second case it links together many cities and, hence, creates a new type of region or corridor with a high interregional accessibility. One important hypothesis for the discussion in this paper is the degree to which cities that are linked together into a band of cities by means of a high-speed train connection are trans-formed to an extended functional region or in other words an integrated corridor economy. Once High-speed railway is completed, it will undoubtedly weaken the effect of rent between inter-cities, make lower costs across the industry. The urban industry will achieve rapidly convergence and fusion.space economic diffusion trend will obviously be enhanced, which makes each city establish position in the area from its own characteristics.With the rapid development of social economy, china is going into a period of rapid development of urbanization. It will present the agglomeration and expansion of the scale. The improvement of urbanization will lead to the increased demand of the passenger transport. The construction and development of high-speed railway play an important role in the development of our country.Firstly, this paper introduces the research background, puts forward the research significance and research content, and points out the research of innovation points and deficiencies. Secondly, in this paper, the high-speed impact on urban space structure, high iron influence on urban economic development, and how to use and one for small and medium-sized cities own development has carried on the thorough research. With the low carbon, energy saving functions of high-speed railway is appearing gradually, it has become the backbone of the transportation system in our country. At the same time the development of high-speed railway will also promote the occurrence of the same effect, which will produce the same increase point of development such as culture, economy, politics, and at the same time it will promote regional and urban development. It will drive the development of industrial and increase the works. In the stage of entering a rapid period of high-speed development, it is important in studying the influence of high-speed railway on urban development, especially the influence of the less developed cities which is important in making the prepared in the urban development. This paper introduces the research background; put forward the research significance and research content, and points out the research of innovation points and deficiencies. Secondly, the fundamental influence of the high-speed railway on the development of the city is changed the accessibility between cities, the article makes a deep research and analysis, as a case of shanghai-Nanjing high-speed rail has carried on the empirical research. As the increased accessibility the connection between the area of cities become more closely. Through the impact of high-speed railway on urban spatial introduces the influence of urban economic development. Due to the time of the high-speed development of our country is relatively short, this paper summarizes the foreign high-speed driving on the less developed cities and finally introduce the road and the noticed problems of the less developed cities. finally, the paper summarize the influence of the less developed cities under the development of high-speed railway and put forward policy Suggestions. |
