备注

高速公路建设水平是一个国家或地区经济实力的体现,在较大程度上会对沿线区域的经济韧性水平产生重要影响。运用面板双向固定效应模型,分析各省域高速公路建设水平对经济韧性的影响,并对其稳健性及异质性进行了深入探讨。研究发现:1)整体上而言,高速公路建设水平能够正向推动省域经济韧性的提升,且经过稳健性检验后依然成立; 2)由经济水平异质性分析表明,中部地区高速公路建设水平对省域经济韧性的促进效应大于东部地区和西部地区; 3)由人口规模异质性分析表明,人口规模越大的省份,其高速公路建设水平对经济韧性的促进效果越显著。研究对于我国高速公路建设政策的完善和省域经济韧性的提升具有一定的意义。
The level of expressway construction is the embodiment of the economic strength of a country or a region, which significantly affects the level of economic resilience of regions along the route to a large extent. By using the panel data and the bidirectional fixed effect model, this paper analyzes the impact of the expressway construction level on economic resilience in various provinces, and discusses in depth their robustness and heterogeneity. The research finds that 1)on the whole, the construction level of expressway can positively promote the improvement of the resilience of provincial economy, and it is still valid after the robustness test; 2)the analysis of economic level heterogeneity shows that the promotion effect of the expressway construction level in the central region on the provincial economic resilience is greater than that in the eastern and western regions; 3)the analysis of population size heterogeneity indicates that the larger the population size of the province, the more significant the promotion effect of its expressway construction level on economic resilience. The research in this paper is of certain significance for improving China's expressway construction policy and promoting provincial economic resilience.
