房地产限购令作为一种调控房价的措施,引来社会广泛争论。我国从中央到地方已经颁布了许多限购令。限购令并不是法律、行政法规或地方性法规,而是一种抽象行政行为。从合法性的角度来说,限购令对对公民的财产权、自由交易权、平等权的限制既不合法,也不合理,违背我国宪法和法律的基本精神。 Real estate restriction order as a measure to control prices, leading to widespread social controversy. China has promulgated many restriction orders from the central authorities to local governments. Restriction order is not a law, administrative regulations or local laws and regulations, but an abstract administrative act. From the point of view of legitimacy, the restriction of restriction order on the property rights, free trading rights and equal rights of citizens is neither valid nor reasonable and violates the basic spirit of our constitution and laws.
