  "abstract": "We use a type 2 AGN sample from SDSS DR7 in which the [O III] {\\lambda}5007 emission line can be modeled by two Gaussian components, a broad wing plus a narrow core, to investigate the origin of the broad wing and the connection between the velocity shift of the broad wing and the physical parameters of active galactic nuclei (AGNs) as well as their host galaxies. We find that the flux of the wing components is roughly equal to that of the core components in statistic. However, the velocity shift of the wing component has only weak, if any, correlations with the physical properties of AGNs and the host galaxies such as bolometric luminosity, the Eddington ratio, the mass of supermassive black holes, D4000, H{\\delta}A or stellar mass. Comparing the velocity shift from our type 2 AGN sample to that from type 1 sample in Zhang et al. (2011), we suggest the [O III] broad wing originates from outflow.",
