AB  - Using e^+e^- collision data collected by the BESIII detector at center-of-mass energies from $3.80$ to 4.95 GeV, the inclusive production cross sections of open-charm mesons, σ(e^+e^−→ D^0/D^+/D_s^++X), are measured by tagging a D^0, D^+, or D_s^+ meson, where X denotes any accompanying particles. Open-charm production dominates the total hadronic yield above threshold. Therefore these measurements provide a vital reference for understanding hadron production and for validating global R value results. The results offer crucial inputs for investigating heavier charmonia and exotic states coupled to open-charm final states, while serving as a benchmark for comparison with the sum of measured exclusive channels. This comparison directly evaluates the completeness of current exclusive datasets and clarifies the underlying hadronization mechanisms in the open-charm region.
