Regional Development With High Speed Railway Based On Knowledge Spillover

There are obvious phenomena of knowledge exchange,labor migration andknowledge industry clustering along the high speed rail(HSR).This phenomenon is related to the differentiated development between regions.In the background of the large-scale operation of the high speed rail in China,the difference of the regional development along the high speed rail is gradually obvious.High speed rail and regional development studies have tended to emphasize the relationship between mechanism explain the various endogenous variables,including communication,spatial structure,industrial and economic effect and so on,but there is no discussion is made on the relationship between the fields,HSR for regional development impact mechanism in interpretation are still lacking,and influence the formulation and implementation of high speed rail policy.Because the HSR promotes the face-to-face communication between people,knowledge spillover has become the most critical research perspective.Knowledge spillover theory has gone through three stages:ignoring spatial factors,considering the distance to knowledge spillover,and emphasizing knowledge spillover,geographical proximity.From the static perspective,knowledge spillovers change from a static perspective to a dynamic perspective,such as mechanism,structural evolution,policy and governance.The distance and localization characteristics of knowledge spillovers originate from the impact of knowledge spillover on the degree of difficulty of regional communication,which reflects geographical proximity.That is,knowledge spillovers,which are contained in human capital,industrial agglomeration and diffusion,are more concentrated on the scope of traffic impact.With the emergence and development of long distance and multi node fast ground transportation represented by high speed railway,people interact more frequently,and the acceleration of industrial agglomeration and diffusion has affected the distance and proximity of knowledge spillovers,and has played an important role in regional development.This research enriches the perspective of high speed railway in regional development,the spatial structure of knowledge spillover is introduced in the distance and localization based on knowledge spillover theory an advance,could indicate the policy system of regional development in high speed railway as the representative of the convenient traffic system.Based on knowledge spillover,the role of regional development have a significant knowledge overflow distance constraints,and the theoretical basis of geographical proximity,the extension of the knowledge spillover to the study of space structure,based on the high-speed railway changes knowledge spillover,constructed the"knowledge spillover effect regional development to high speed railway changes knowledge spillover,high-speed rail impact regional development" of the analytical framework.First summarizes the overflow medium and the necessity of the recessive knowledge spillover,on the basis of the structure change of knowledge spillovers under analysis under the industrial division of labor and department division of labor and industrial agglomeration spatial differentiation,inductive knowledge spillover space structure including "development,since the choice,networked,differentiation"four stages.Next,based on the theory of knowledge spillover,explain the mechanism of regional development of high-speed railway is:mediated,structural,sexual knowledge node,the overflow of the space structure of regional development and knowledge interaction;passenger travel choice before and after then,by the HSR opened build travel time weight,describing high-speed opening knowledge before and after the talent agglomeration degree and spatial structure of regional knowledge spillovers,and explain to change;Finally,the paper makes case explanations and policy Suggestions on the mechanism and path of high-speed rail and regional development respectively from the two levels of media and structure effect and knowledge node effect.The main conclusions of this paper are as follows:Second,the difference in the regional development of the high speed railway is determined by the phase difference of the spatial structure of knowledge spillover.High speed railway is the medium of knowledge spillover,and the difference of information and communication technology lies in the realization of the flow of labor.The mechanism of high speed railway affecting regional development includes media,structure and knowledge node.As a medium of knowledge spillovers,high-speed railway shortens travel time,promotes face-to-face communication and improves the proximity of tacit knowledge spillovers,which is a supplement to existing knowledge spillovers.In terms of structure,high-speed railway affects the differentiation of heterogeneous labor flow,the differentiation of industrial agglomeration and diffusion,and presents the inner gradient of knowledge spillover.In terms of knowledge nodes,high-speed railway expands the radiation range of the original knowledge nodes,produces siphon effect on headquarters economy,and promotes further division of labor among knowledge departments,creating new knowledge centers,and remodeling the spatial structure of knowledge spillovers.Third,the spatial structure of knowledge spillovers under the influence of high speed rail has undergone four stages:development,self selection,network and differentiation.Stage of development is reflected in the construction of high-speedrailway will attract some labor,capital and intermediary services,to promote knowledge of sites in the city and regional impact of high-speed railway on the spatial structure of the more effect on regional original labor and industry,including in order to adapt to the policy adjustment of the construction of high-speed rail industry.Since the selection stage,regional exchanges could choose the convenient traffic,knowledge complementary area,population agglomeration and diffusion has selectivity,passenger attached on the site itself knowledge agglomeration,and along the high wire industry diffusion,with the opening of high-speed rail spontaneously re configuration,knowledge center,and a plurality of regional division system into.The development stage of network network shows the nature of the hub in some cities along the high speed railway.High speed railway to further promote the regional division of labor,effectively improve the knowledge spillover effect between the upstream and downstream industries,improve the knowledge of the professional sector value,also provides goods in regional trade circulation channels,promote regional cooperation,enhance the overall regional output efficiency.The differentiation stage is the stage that the spatial structure of knowledge spillovers under the guidance of high-speed rail is gradually shaping.It not only promotes the upgrading and growth of knowledge nodes,but also exacerbates the process of knowledge imbalance spillover.Fourth,by introducing the time accessibility weight of travel choice,combined with SDM model,it is confirmed that the rule of knowledge spillover attenuation depends on the time distance of labor exchange when high-speed railway is affected.Further through the concentration of high skilled labor and the spatial autocorrelation model,the development stage of the spatial structure of knowledge spillover is demonstrated.In the region with significant results,the northeast is in the stage of development,and Jiangxi is in the stage of self selection.The East has entered the stage of network,and the whole is different.The Northeast should be through to the point",to adjust the industrial structure,improve the level of education as the main motive force of development.Jiangxi should pay more attention to the role of the link and link of the high speed rail and further cooperation and exchange with the surrounding regions.Network area should emphasize the impact of high-speed rail hub on urban development,and re-examine the agglomeration of urban industry.We should avoid the differentiation effect brought by different spatial structure of knowledge spillovers,and also emphasize the promotion role of high-speed rail hub to knowledge spillovers.The main innovations of this paper are as follows:first,the introduction of spatial structure of knowledge spillover is the theory innovation and regional development mechanism to reveal the traffic necessary and in urgent need to high-speed rail as the representative of the convenient traffic system,the spatial structure of knowledge spillover is introduced in the distance and localization based on knowledge spillover theory a boost reflects the dynamic relationship between knowledge spillover in space and interaction mechanism of innovation;second,the influence of high-speed railway regional development,based on the knowledge spillover theory as a clue,the differences in regional development of high-speed railway is determined by the phase difference of knowledge spillover in spatial structure,and puts forward the development strategy of different stages;third,the innovation of knowledge spillover based on the empirical aspect,before and after the high-speed railway travel time changes as the foundation,constructed the regional high Tieke The weight of the accessibility of traffic is estimated and the attenuation effect of knowledge spillover is estimated.
