Against the backdrop of increasing global supply chain uncertainties, how to enhance the ability of ports to cope with external shocks has become a hot topic in both academia and industry. To this end, this study is based on panel data of 16 listed Chinese port companies from 2004 to 2023. A web crawling technique was used to obtain the text of corporate annual reports. The term frequency-inverse document frequency method was applied to extract the frequency of digitalization-related keywords, so as to quantify the degree of digital technology application. Meanwhile, the sensitivity index method was used to measure the level of port resilience. On this basis, a fixed-effects model was further constructed to empirically examine the empowering effect of digital technology on port resilience and its underlying mechanism. The results show that the application of digital technology significantly improves the resilience of major Chinese ports. For each standard deviation increase in the digital technology level, port resilience increases by about 0. 2 standard deviations. This finding remains valid after a series of robustness tests. Digital technology exerts its effect by strengthening absorptive capacity and adaptive capacity, among which the enhancing effect on adaptive capacity is particularly prominent. However, the path of improving resilience through innovation capacity has not yet emerged. Under the impact of the 2020 global public health event, the empowering effect of digital technology on port resilience was significantly enhanced. In contrast, under the impact of climate change and the 2008 financial crisis, the empowering effect of digital technology on port resilience did not change significantly. These conclusions provide a new perspective for seeking to improve port resilience in the current context of sharply increasing global uncertainties.

在全球供应链不确定性加剧的背景下,如何增强港口应对外部冲击的能力成为学界和业界关注的热点问题。为此,文章基于2004年至2023年中国16家港口上市公司的面板数据,采用网络爬虫技术获取企业年报文本,利用逆文档概率词频法提取数字化相关关键词频以量化数字技术应用程度,同时运用敏感性指数法测度港口韧性水平。在此基础上进一步构建固定效应模型实证检验数字技术对港口韧性的赋能效应及其作用机制。结果表明:数字技术应用能够显著提升中国主要港口的韧性,数字技术水平每提高1个标准差,港口韧性将增加约0.2个标准差,且该发现在经过一系列稳健性检验后仍然成立;数字技术通过强化吸收能力和适应能力发挥作用,其中对适应能力的增强效应尤为突出,而通过创新能力提升韧性的路径尚未显现;在2020年全球公共卫生事件冲击下,数字技术对港口韧性的赋能效应得到显著增强,而在面临气候变化和2008年金融危机冲击时,数字技术对港口韧性的赋能效应并未发生显著变化。这些结论为当前全球不确定性骤增背景下寻求港口韧性的提升提供了新的视角。

在全球供应链不确定性加剧的背景下,如何增强港口应对外部冲击的能力成为学界和业界关注的热点问题。为此,文章基于2004年至2023年中国16家港口上市公司的面板数据,采用网络爬虫技术获取企业年报文本,利用逆文档概率词频法提取数字化相关关键词频以量化数字技术应用程度,同时运用敏感性指数法测度港口韧性水平。在此基础上进一步构建固定效应模型实证检验数字技术对港口韧性的赋能效应及其作用机制。结果表明:数字技术应用能够显著提升中国主要港口的韧性,数字技术水平每提高1个标准差,港口韧性将增加约0.2个标准差,且该发现在经过一系列稳健性检验后仍然成立;数字技术通过强化吸收能力和适应能力发挥作用,其中对适应能力的增强效应尤为突出,而通过创新能力提升韧性的路径尚未显现;在2020年全球公共卫生事件冲击下,数字技术对港口韧性的赋能效应得到显著增强,而在面临气候变化和2008年金融危机冲击时,数字技术对港口韧性的赋能效应并未发生显著变化。这些结论为当前全球不确定性骤增背景下寻求港口韧性的提升提供了新的视角。

Against the backdrop of increasing global supply chain uncertainties, how to enhance the ability of ports to cope with external shocks has become a hot topic in both academia and industry. To this end, this study is based on panel data of 16 listed Chinese port companies from 2004 to 2023. A web crawling technique was used to obtain the text of corporate annual reports. The term frequency-inverse document frequency method was applied to extract the frequency of digitalization-related keywords, so as to quantify the degree of digital technology application. Meanwhile, the sensitivity index method was used to measure the level of port resilience. On this basis, a fixed-effects model was further constructed to empirically examine the empowering effect of digital technology on port resilience and its underlying mechanism. The results show that the application of digital technology significantly improves the resilience of major Chinese ports. For each standard deviation increase in the digital technology level, port resilience increases by about 0. 2 standard deviations. This finding remains valid after a series of robustness tests. Digital technology exerts its effect by strengthening absorptive capacity and adaptive capacity, among which the enhancing effect on adaptive capacity is particularly prominent. However, the path of improving resilience through innovation capacity has not yet emerged. Under the impact of the 2020 global public health event, the empowering effect of digital technology on port resilience was significantly enhanced. In contrast, under the impact of climate change and the 2008 financial crisis, the empowering effect of digital technology on port resilience did not change significantly. These conclusions provide a new perspective for seeking to improve port resilience in the current context of sharply increasing global uncertainties.
