Although the application of blockchain technology in maritime industry can improve the customs clearance efficiency and logistics transparency in the container cargo supply chains, it generates the unit operations cost and setup cost. In this study, a spatial model is proposed to conduct an investigation into the two heterogeneous ports when blockchain technology is applied under inter-port competition. Different utility-driven operations models are built to highlight the values of blockchain technology for port logistics capability, and to reveal the equilibria under the optimal strategies and equilibrium strategies. It is noticed that the relationship between the unit net benefit and unit operations cost brought out by blockchain technology is a key factor determining whether the blockchain technology is applicable. When the unit operations cost is lower than unit net benefit, and the setup cost is high, there is a win-win situation for two ports to apply traditional technology. It is further verified to be Pareto-optimal. In addition, three lose-lose situations are also identified, which are classic Prisoner's Dilemmas. Consequently, a horizontal collaboration mechanism “blockchain technology sharing + compensation” (BTSC) is designed to not only break these three Prisoner's Dilemmas, but also achieve the Pareto-optimum. Furthermore, we discuss some extensions to prove the robustness of our main qualitative insights.

区块链技术在海运业的应用虽然可以提高集装箱货物供应链的通关效率和物流透明度，但会产生单位运营成本和设置成本。在本研究中，提出了一个空间模型来对在港口间竞争下应用区块链技术时的两个异构港口进行调查。构建不同的效用驱动运营模型，以突出区块链技术对港口物流能力的价值，揭示最优策略和均衡策略下的均衡。值得注意的是，区块链技术带来的单位净收益与单位运营成本的关系是决定区块链技术是否适用的关键因素。当单位运营成本低于单位净收益，且设置成本较高时，两个港口应用传统技术可实现双赢。进一步验证为帕累托最优。此外，还确定了三种双输情况，它们是经典的囚徒困境。因此，“区块链技术共享+补偿”（BTSC）的横向协作机制旨在不仅打破这三个囚徒困境，而且实现帕累托最优。此外，我们讨论了一些扩展，以证明我们的主要定性见解的稳健性。还确定了三种双输情况，它们是典型的囚徒困境。因此，“区块链技术共享+补偿”（BTSC）的横向协作机制旨在不仅打破这三个囚徒困境，而且实现帕累托最优。此外，我们讨论了一些扩展，以证明我们的主要定性见解的稳健性。还确定了三种双输情况，它们是典型的囚徒困境。因此，“区块链技术共享+补偿”（BTSC）的横向协作机制旨在不仅打破这三个囚徒困境，而且实现帕累托最优。此外，我们讨论了一些扩展，以证明我们的主要定性见解的稳健性。
