| Transport infrastructure is the foundation of the national economy important industry,is the important support and guarantee to promote the development of various undertakings,the impact on strategic,overall economic and social development.Previous studies have focused on the relationship between transportation infrastructure and economic growth and the economic benefits of etc.These years,more and more scholars begin to pay close attention to infrastructure facilities spatial spillover effects.About transport infrastructure,however,for a specific research on the effects of regional industry spatial spillover effects or less,some are only limited to the eastern coastal developed areas.The five northwestern provinces as frontier economic belt "silk road" construction,has important strategic position.Based on this,this article in the five provinces of northwestern China manufacturing industry as the research object,by evaluating transportation infrastructure for the five northwestern provinces manufacturing total factor productivity spillover effects of space,transportation investment policies for the five northwestern provinces,promote the transformation and upgrading of manufacturing industry to provide the reference suggestion.This paper is based on the endogenous growth theory and new economic geography theory,the externality theory of three reasoning transportation infrastructure by promoting regional integration process,reduce the production cost,manufacturing enterprise manufacturing enterprise agglomeration effect three paths exist space manufacturing total factor productivity.Second on the five northwestern provinces traffic infrastructure development situation to do a brief description and manufacturing and using the Malmquist productivity index method based on data envelopment analysis method to measure out the five northwestern provinces during2004-2014 manufacturing total factor productivity growth rate and its decomposition.The results show that,a decade the five northwestern provinces manufacturing total factor productivity average annual growth rate of 6.2%,during the ups and downs;Technology progress is the five northwestern provinces manufacturing efficiency of the main way,its average annual growth rate of 8.2%,the change of the scale efficiency to promote the efficiency of manufacturing is weak;Five provinces decade average manufacturing total factor productivity growth is positive,all that decade to improve the manufacturing efficiency of the five northwestern provinces.Then using exploratory space analysis method for inspection of manufacturing total factor productivity growth rate between the provinces spatial correlation,the analytical results show that since 2008,the five northwestern provinces manufacturing total factor productivity spatial correlation exists,and in 2007 years later,the five provinces manufacturing total factor productivity moran,’I index is positive and mainly presented the rising momentum,suggests five provinces manufacturing total factor productivity growth rate of spatial correlation is more and more strong,moran scatter diagram shows high correlation and the low correlation is the five northwestern provinces manufacturing total factor productivity between the main forms of distribution.Spatial lag model is set up,and then empirically transportation infrastructure for the five northwestern provinces manufacturing total factor productivity spatial spillover effect,and draw the following conclusion: transportation infrastructure for the five northwestern provinces manufacturing total factor productivity spillover effects exist space,in which the local effect is 0.061,the spillover effect is 0.0274,increased investment in transportation infrastructure that not only can promote the development of the local manufacturing,and to promote the development of surrounding cities;In addition to transportation infrastructure,opening to the outside world level,r&d investment,government spending that three control variables are also showed a significant positive correlation,improve the level of opening to the outside world,increase r&d investment,government spending to boost the five northwestern provinces manufacturing total factor productivity,foreign direct investment,human capital is not through the test of significance.Finally,according to the above conclusions,from relying on characteristic resource advantage,build regional autonomous brand;Encourage the development of industry cluster,improve the level of industrial concentration;Play a role of talents and funds push to the development of manufacturing industry;Accelerate the construction oftransportation infrastructure,improve the utilization efficiency of transport infrastructure four aspects put forward relevant policy Suggestions. |
