黑名单是东西方普遍存在的法律经济现象。但是由于国内法律法规的缺位,导致法学界和民间对民间黑名单的合法性存在不少争议,集中在对是否构成非法限制投标人、是否构成名誉侵权、是否属于滥用市场地位三个方面。本文针对这三个争论展开论述,通过论证得出黑名单是当前我国信用管理体制尚未健全前的必要措施。 Blacklists are the common economic and legal phenomena in East and West. However, due to the absence of domestic laws and regulations, there is much controversy over the legitimacy of the non-governmental blacklists by legal circles and civilians, focusing on three aspects: whether it constitutes illegitimate infringement and whether it constitutes abuse of market position. This article discusses these three controversies, and proves that the blacklist is the necessary measure before the current credit management system in our country is not perfect.
