摘　　要：We discuss recent measurements of exclusive e^＋e^- cross sections for charmed hadron final states near threshold performed by Belle and BABAR. The results are based on a study of events with initial-stateradiation photons in a large data sample collected with the Belle and BABAR detectors at the T（4S） resonance and nearby continuum.We discuss recent measurements of exclusive e^＋e^- cross sections for charmed hadron final states near threshold performed by Belle and BABAR.
