To Get Rich,Build Roads First:Transportation Infrastructure Construction and Economic Growth
Based on the provincial panel data in China,this paper uses the panel vector autoregressive(PVAR)model to empirically analyze the dynamic relationship,interaction mechanism,and regional differences between transportation infrastructure construction and economic growth.The findings show that transportation infrastructure construction and economic growth in China generally depend on their own development,and there is a mutual positive impact between the two,but the impact degree of economic growth on transportation infrastructure construction is greater than that of transportation infrastructure construction on economic growth.From a regional perspective,there are certain regional differences in the relationship between the two.The economic development and transportation infrastructure construction in the eastern region are more dependent on their own development,while the economic development in the central and western regions is relatively more dependent on investment in transportation fixed assets.The impact of transportation infrastructure construction on economic growth has a lag,which is more significant in the central and western regions.Based on the conclusions,countermeasures and suggestions are put forward;Increasing effective investment,and strengthening the economic function of transportation;Using science and technology to promote the sustainable development of the transportation system;Optimizing the investment strategy in transportation infrastructure,and tilting towards underdeveloped regions.
