In　this　research　we　examine　the　Community　of　Inquiry　model　and　further　develop　the　model　by　integrating　a　complementary　institutional　presence.　For　this　purpose,　a　questionnaire　including　five　presences　and　73　questions　was　designed.　In　total,　a　response　of　762　questionnaires　from　five　universities　were　collected.　Correspondingly,　statistical　analysis　like　factor　analysis　and　structural　equation　model　were　conducted.　The　present　paper　is,　duly,　a　quantitative　investigation　of　the　correlations　between　institutional　presence　and　other　presences　in　the　new　model　as　well.　Finally,　a　further　developed　Community　of　Inquiry　model　that　integrates　institutional　presence　is　generated.　With　a　relatively　large　sample,　the　results　meet　the　applicable　requirements,　indicating　that　the　generated　model　is　acceptable　and　fits　well　with　the　data.
