要想富,先修路:交通设施建设与经济增长

To Get Rich, Build Roads First:Transportation Infrastructure Construction and Economic Growth

基于我国省级面板数据,采用面板向量自回归(PVAR)模型,对交通设施建设与经济增长间的动态关系、作用机制及区域差异进行实证分析.研究表明:我国交通设施建设和经济增长整体上依赖自身发展,二者之间存在相互正向影响,但经济增长对交通设施建设的影响程度大于交通设施建设对经济增长的影响程度.分地区来看,二者之间的关系存在一定的区域差异:东部地区经济增长及交通设施建设更依赖自身发展,中部和西部地区经济增长相对更依赖交通固定资产投资;交通设施建设对经济增长的影响存在滞后性,而中部和西部地区的滞后性更显著.基于研究结论,提出以下对策建议:增加有效投资,强化交通运输经济功能;利用科技促进交通系统的可持续发展;优化交通设施投资策略,向欠发达地区倾斜.

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.
