A Research About The Impact Of Technological Evolution Of Transportation Infrastructure On Upgrading Of Industrial Structure

Economic competition in the final analysis is industrial competition. Country’s overall economic competitiveness depends greatly on international competitiveness of its major industry. Following the trend of the economic globalization and knowledge economy, service became the foundational industry of our society. Since China’s reform and opening up, its industrial structure adjustment and optimization have been accelerated and economic development achieved remarkable results with overall national strength increasing greatly.As a social capital, transportation infrastructure is an important prerequisite that obtains economic development.Along with the constant development of transportation technology, more and more new vechiles were researched and put into practice. High-speed railway as a high-speed and energy-efficient vechile, was favored by the government of each country. In the next few years, our country will enter a period of harvest.Being from the construction mode of developed countries, our country’s model is that the technology and infrastructure existed was improved gradually such as Beijing-Shanghai Railway and Beijing-Kowloon Railway. In other words, our country follows the line that the technology evolves gradually. Combining the building of high-speed railway and industrial structure upgrading, the paper will explore how to upgrade the industrial structure of china and solve the problem that whether the technological evolution of transportation infrastructure could promote industrial structure upgrading.Theortically, this paper firstly summarizes the two economic characteristics of transportation infrastructure:network and knowledge spillover. They raises the relationships between technological evolution of transportation infrastructure and knowledge spillovers. We consider that the economics implication of the opening of high-speed railway will raiseand speed up the tacit knowledge spillover. Finally combining with relationship between the knowledge spillover and the industrial structure, this paper proposes technological evolution of transportation infrastructure—knowledge spillover—industrial structure upgrading. Baseing on the theory of intra-product specialzation, this paper set up the theoretical model of the transport infrastructure development and industrial structure. It concluded two important propositions. Proposition 1:technological evolution of transport infrastructure will short the travelling time among cities, accelerate knowledge spillover and reduce variable cost, which promote technical services transferring from developed area to developing area. Therefore, we make a conclusion that industrial structure of the cities connecting transportation infrastructure will be promoted. Proposition 2:The relative accessibility of the region is higher, the level of industrial structure is higher.Empirically, the paper using the data of 26 cities of Yangtze River Delta region in 2003-2011, estimates dynamic panel data model. The empirical results shows Shanghai-Nanjing-Hangzhou multiple unit can promote local industrial structure upgrading. Therefore, the proposition of the paper is proved. We find relative accessibility is an important influencing factor. The relative accessibility is an important factor deciding the level of industrial structure.The relative accessibility of the city is higher, the level of industrial structure is higher. Additionally, we will investigate the effect what Shanghai-Nanjing-Hangzhou multiple promoted local industrial structure upgrading according division of industries. The empirical results shows the opening of Shanghai-Nanjing-Hangzhou multiple unit just promoted the industry share of finance increasing, the industry share of the other industries not remarkable. Because the difference of industrial characteristics will impact absorbing capacity of knowledge. Technical gap will bring more difficult for the behavior of learning and imitation, which hindered absorbing knowledge spillovers and leaded to imbalanced development of the industry.From the perspective of urban system, the intension of industrial structure upgrading includes not only evolution of industrial sector of the menber cities but regional division of labor relationship-industrial strucutre of urban system. Basing on this, our paper investigate the mechanism about which technological evolution of transportation infrastructure impact on industrial structure of urban system. According to the extension analysis of the above model, we consider that technological evolution of transportation infrastructure not only could promote industrial structure upgrading but raise the level of specialization. After the theoretical theorem was achieved, our paper captures data of Yangtze Delta megalopolis for empirical analysis. Empirical result reveals that the opening of Shanghai-Nanjing-Hangzhou multiple unit promote industrial strucutre of urban system of the Yangtze delta upgrading.Finally, According to the above research results, our paper analyse the influences hindering industrial structure of Yangtze delata upgrading. Some suggestion are given from industrial structure of member upgrading and industrial structure of urban system upgrading.
