The Spatial Spillover Effect Of Transportation Infrastructure Scale In Xinjiang’s Economic Growth

Transport infrastructure is an essential prerequisite for economic development. The relationship between transport infrastructure and economic growth is a research hot-spot. Previous researcher mainly focused on the benefits of transport infrastructure and the relationship between transport infrastructure and economic development. The researchers mostly ignored the spatial spillover effects of transport infrastructure. The researchers assume that all regions were homogeneous and independent. But region is mutual related and not isolated. There are a few researches on spillover effects of transport infrastructure in china. The papers mostly use provincial data. This paper aims to reveal spatial spillover effects of transport infrastructure on regional economics of Xin Jiang Province.This paper firstly constructs a theoretical frame to explain the spatial spillover effect of transport infrastructure on economic growth. This paper assumes transport infrastructure has spatial spillovers effect on regional economic development. The spatial spillovers effect is either positive or negative. Exploratory spatial data analysis and spatial econometric techniques be used in the empirical research. ESDA is used to draw spatial distribution of TFP. From the Moran’s I scatter diagram, we find that TFP show an evident feature of spatial cluster. Last we use Malmquist index of productivity of Xin Jiang province with 15 regional total factor productivity, then we analysis the spatial spillover effects of transport infrastructure by spatial econometric models. We deduce the following conclusions from this paper.(1)From 2000 to 2012 the total factor productivity average of 15 regions is less than 1, decreased by 2.1% in this 13-year period.(2)Moran’s I is a fluctuating trend, roughly divided into three stages: the first phase from 2001 to 2006 showed a rising trend, the second stage was to narrow the trend from 2006 to 2008, the third phase is a growing trend from 2008 to 2012. The adjacent transport infrastructure has spatial spillovers effect to local economic development. The spatial spillover effect from transport infrastructure is largely positive.(3)The empirical research shows that, the spill-over from the infrastructure into the regional economic growth in Xin Jiang province are significant on the overall performance. Human resources and Industrial structure has significantly promoted TFP in Xin Jiang.In short, infrastructure investment has remarkably promoted the TFP in Xin Jiang area. There are Spatial spillover effects between two cities. Based on the above conclusions, we propose many suggestions on investment and layout of transport infrastructure.
