房屋拆迁，其法律实质是政府根据公共利益原则（共益设施建设或城市改造），向土地使用权人收回土地使用权并由此必然地要求土地使用人放弃地上物权即房屋所有权的行为，这是私有财产不受侵犯和自愿原则的例外，因此政府相应地遵循公平和等价有偿原则给被拆迁人以合理补偿，保 The legal essence of the house demolition is that the government reclaims the land use right from the land user according to the principle of public interest (construction of shared facilities or urban renewal) and thus inevitably requires the land user to give up the real property on the ground, that is, the ownership of the house. Is the exception of the principle of inviolability of private property and the principle of voluntariness. Therefore, the government accordingly follows the principle of fairness and equal payment to compensate the demolished people with reasonable compensation.
