We perform a systematic study of evolutionary stages and stellar masses ofyoung stellar objects (YSOs) in the Large Magellanic Cloud (LMC) to investigateproperties of star formation of the galaxy. There are 4825 sources in our YSOsample, which are constructed by combining the previous studies identifyingYSOs in the LMC. Spectral energy distributions of the YSOs from optical toinfrared wavelengths were fitted with a model consisting of stellar, polycyclicaromatic hydrocarbon and dust emissions. We utilize the stellar-to-dustluminosity ratios thus derived to study the evolutionary stages of the sources;younger YSOs are expected to show lower stellar-to-dust luminosity ratios. Wefind that most of the YSOs are associated with the interstellar gas across thegalaxy, which are younger with more gases, suggesting that more recent starformation is associated with larger amounts of the interstellar medium (ISM).N157 shows a hint of higher stellar-to-dust luminosity ratios between activestar-forming regions in the LMC, suggesting that recent star formation in N157is possibly in later evolutionary stages. We also find that the stellar massfunction tends to be bottom-heavy in supergiant shells (SGSs), indicating thatgas compression by SGSs may be ineffective in compressing the ISM enough totrigger massive star formation. There is no significant difference in thestellar mass function between YSOs likely associated with the interface betweencolliding SGSs and those with a single SGS, suggesting that gas compression bycollisions between SGSs may also be ineffective for massive star formation.
