摘要

本文评估了道路基础设施投资对布基纳法索经济结构竞争力的非线性影响。在保留1980 - 2015年期间后,二次和样条估计显示结构经济竞争力与道路基础设施投资之间存在非线性关系。事实上,二次估计识别出非线性u型倒转,最优阈值为10.11%。对于样条估计,它也突出了这种非线性,并给出了最优区间[5%;15%]。从这些结果中得出的经济政策启示是,为了从最优的结构竞争力中受益,道路基础设施投资在总投资预算中的份额必须在5%到15%之间。

Non-linear Effects of Investment in Road Infrastructure on the Structural Competitiveness of the Economy: The Case of Burkina Faso
This paper assesses the non-linear effects of road infrastructure investment on the structural competitiveness of Burkina Faso's economy. After retaining the period from 1980 to 2015, the quadratic and spline estimation revealed a non-linearity between the structural economy competitiveness and investment in road infrastructure. Indeed, the quadratic estimate identified non lineary U-shaped inverted with an optimal threshold of 10.11%. With regard to the spline estimation, it also highlighted this nonlinearity and gave an optimal interval of [5%;15%]. The economic policy implication that emerges from these results is that in order to benefit from optimal structural competitiveness, the investment’s share in road infrastructure in the total investment budget must be between5% and 15%.
