To investigate how the digital transformation of port firms improves their operational resilience, we design methods to measure their digital transformation grade (DTG), technological innovation capacity (TIC), and port operational resilience (POR) respectively. Based on 3586 samples retrieved from 334 Chinese port firms from 2011 to 2021, their relationships are statistically described and preliminarily regressed by an ordinary least-squares model and a fixed-effect model. After testing the effects of supply chain disruption, endogeneity, and robustness, we reveal that digital transformation improves firms' competitiveness and operational resilience by coordinating human resources, information, and technology. We confirm that TIC plays an intermediate role and an adverse event has an enhancement effect. An inverted-U curve between DTG and POR proves that port firms often suffer growing pains at the initial stage and their POR will be promoted by continuous digital inputs, but the leading port firms would gain fewer marginal benefits.
为探究港口企业数字化转型如何提升其运营韧性，我们分别设计了衡量其数字化转型程度（DTG）、技术创新能力（TIC）和港口运营韧性（POR）的方法。基于 2011 年至 2021 年间从 334 家中国港口企业中获取的 3586 个样本，通过普通最小二乘法模型和固定效应模型对它们之间的关系进行了统计描述和初步回归。在检验了供应链中断、内生性和稳健性的影响后，我们揭示了数字化转型通过协调人力资源、信息和技术来提高企业的竞争力和运营韧性。我们证实 TIC 发挥了中介作用，突发事件具有增强效应。DTG 和 POR 之间的倒 U 型曲线表明，港口企业在初始阶段往往会经历成长的痛苦，其 POR 将随着数字化投入的不断增加而得到提升，但领先的港口企业获得的边际收益会越来越少。
