In 2023, China's import of marine propulsion spark-ignition engines was recorded at 191.86 s. The forecast for 2024 indicates a decline to 180.44 s, marking a year-on-year decrease of 5.95%. This declining trend is expected to continue, with further reductions in value projected until 2028, culminating in a value of 136.98 s, representing an overall CAGR of approximately -6.57% over the five-year period. Such a downward trend suggests a consistent decline in imports, likely indicative of changes in domestic demand, shifts to alternative propulsion technologies, or increased domestic production capabilities.

Future trends to watch for in this sector include:

Technological advancements in marine engine efficiency and sustainability, potentially driving shifts in import needs.
Policy changes impacting marine fuel standards, which could influence import patterns.
Domestic marine engine production developments that might reduce dependency on imports.
