享有 (xiǎng yǒu) is a formal verb for 'enjoy' or 'be entitled to', used specifically with rights, privileges, and benefits. It contrasts with 享受 (xiǎng shòu), which is broader and about sensory/experiential enjoyment, and 行使 (xíng shǐ), which means to actively exercise a right or power. 享用 (xiǎng yòng) is narrower, for concrete things like facilities or food.
