摘要为了提高内陆港口效率,本文采用希克斯-莫尔斯汀指数衡量了2005年至2016年长江流域18个内陆港口的全要素生产率,并建立了互联网发展影响港口全要素生产率的非线性计量模型。结果表明,长江港口全要素生产率水平呈现明显上升趋势,主要得益于生产技术的明显进步和效率的提高。大型港口的全要素生产率显著提高,而中小型港口的全要素生产率有所下降。对港口全要素生产率的门槛效应进行了实证研究,结果表明,在经济发展水平较高的地区,互联网提高了港口全要素生产率。但是,在经济水平较低的地区,互联网的发展阻碍了全要素生产率的提高。基于港口规模、经济水平和互联网发展趋势,提出了提高长江港口全要素生产率的相关政策建议。
ABSTRACT To improve inland ports efficiency, this paper uses the Hicks-Moorsteen index to measure the TFP of 18 inland ports on the Yangtze River from 2005 to 2016 and establishes a nonlinear measurement model of internet development affecting port TFP. The results show that the TFP level of Yangtze River ports shows a clear upward trend, mainly due to the obvious progress of production technology and the improvement of efficiency. The TFP of large-scale ports has significantly improved while the TFP of small and medium-sized ports has declined. The threshold effect of TFP was studied empirically, showing that in areas with high levels of economic development, the Internet improves port TFP. However, internet development in areas with lower economic levels has hindered the improvement of TFP. Based on port size, economic level, and internet development trends, this paper proposes relevant policy recommendations for improving the TFP of Yangtze River ports.
