摘要
交通基础设施质量的改善能够引致更为充分的市场竞争,促使资源流向更具效率的地方。本文将2007年铁路提速视为中国交通基础设施质量提升的一次准自然实验,以首次开通的动车组列车为分组依据,通过倍差分析法研判铁路提速对企业全要素生产率的影响。分析结果显示:铁路提速对沿途企业的技术进步和效率改进发挥了积极作用,促进了全要素生产率的增长。区分地区特征和企业异质性后的分析结果表明,铁路提速对非国有控股、沿海地区、出口型企业具有更为显著的生产率促进效应,安慰剂检验验证了上述结论。此外,在进一步划分地理圈层后,本文发现位于技术中心城市"1小时经济圈"内的企业更易受到铁路提速带来的外部性影响。
Quality improvements in transportation infrastructure have been widely believed to be capa-ble of increasing competition and the efficient allocation of resources.Based on the quasi-natural experi-ment of Chinese railway speed acceleration in 2007 and the Difference in Differences method,this paper has provided a detailed analysis on the influence of quality improvements in transportation infrastructure on the firm.s total factor productivity in China.Overall,the empirical results reveal a positive effect on the firms.technological progress and efficiency improvement,which has lead to a growth in TFP.Based on sub-samples divided by different regions and types of enterprises,further analysis indicates that the productivity of coastal,non-state controlled and export-oriented firms have been affected by railway speed acceleration.The results are robust concerning the different methods and samples.Firms within the“one-hour economic circle”have been shown to be more vulnerable to the effect of railway speed increase.In essence,the poli-cy implication that stems from all this is that quality improvements of the transportation infrastructure in less developed regions should be emphasized to increase firm productivity and to reduce the regional develop-ment gap.
