In this work, a nearby luminous AGN sample is selected from HST, where onlysources with both X-ray emission observed by \textit{Chandra/XMM-Newton} andradio flux detected by VLA/VLBA/VLBI/MERLIN are adopted to keep high precision.We get a sample of 30 luminous AGNs finally, which consist of 11 RLAGN and 19RQAGN. It is found that the relationship between $R_{\rm {UV}}$ and$\alpha_{\rm {ox}}$, which was firstly reported by Li & Xie (2017) in LLAGN,and other relationships are all absent in RLAGN, probably due to the complexphysical process therein. Our results indicate that the X-ray emission from jetshould play an important role in RLAGN and further support the transition ofaccretion mode between LLAGN and RLAGN. On the other hand, the traditionalrelationships in RQAGN, such as $\alpha_{\rm {ox}}$ and $\lambda$, $\Gamma$ and$\lambda$, are found to be well consistent with previous works.
