The cruise industry in China has experienced relatively slow growth compared to the global market,
despite its increasing economic importance. This study aims to explore a more efficient mechanism for
the synergistic development of the cruise industry chain in China by constructing a system dynamics
model. The model evaluates the upstream, midstream, and downstream segments of the cruise value
chain and examines the causal relationships among value nodes. By assessing the characteristics
and inter-connections of each segment, the study qualitatively analyzes the synergies within the chain
and develops a framework for collaborative development. Vensim software is employed to simulate
the cruise industry’s evolution in Shanghai, identifying the main factors influencing synergy across
the chain. The findings offer theoretical and methodological guidance for enhancing coordination
across industry sectors and improving policy-making. This paper contributes original insights into the
interactions between different segments of the cruise industry chain and proposes a dynamic model
for fostering collaborative growth. By quantifying interdependencies and simulating their economic
impacts, the research provides actionable strategies to support integrated development. The proposed
model supports strategic planning, enhances value creation, and lays the groundwork for more cohesive
growth within China’s cruise industry.
