Early Herbig Be (HBe) stars are massive, young stars accreting through theBoundary Layer mechanism. However, given the rapid ($<$ 2 Myr) evolution ofearly Herbig stars to the main-sequence phase, studying the evolution of thecircumstellar medium around these stars can be a cumbersome exercise. In thiswork, we study the sample of early (B0-B5) HBe stars using the correlationbetween H$\alpha$ emission strength and near--infrared excess, complemented bythe analysis of various emission features in the X-Shooter spectra. Wesegregate the sample of 37 early HBe stars based on the median values ofH$\alpha$ equivalent width (EW) and near--infrared index (n(J$-$H))distributions. The stars with |H$\alpha$ EW| $>$ 50 {\AA} and n(J$-$H) $>$ -2are classified as intense HBe stars and stars with |H$\alpha$ EW| $<$ 50 {\AA}and n(J$-$H) $<$ -2 as weak HBe stars. Using the VLT/X--Shooter spectra of fiveintense and eight weak HBe stars, we visually checked for the differences inintensity and profiles of various H{\sc I} and metallic emission lines commonlyobserved in Herbig stars. We propose that the intense HBe stars possess aninner disk close to the star (as apparent from the high near-infrared excess)and an active circumstellar environment (as seen from high H$\alpha$ EW valueand presence of emission lines belonging to Fe{\sc II}, Ca{\sc II}, O{\sc I}and [O{\sc I}]). However, for weak HBe stars, the inner disk has cleared, andthe circumstellar environment appears more evolved than for intense HBe stars.Furthermore, we compiled a sample of $\sim$58,000 emission-line stars publishedin \textit{Gaia DR3} to identify more intense HBe candidates. Furtherspectroscopic studies of these candidates will help us to understand theevolution of the inner ($\sim$a few au) disk in early HBe stars.
