Since 2000 almost twenty kinds of real name system have come into being. Totally speaking those practices are not really ideal. Most relative researchers put there attention to the single real name system, and neglect the entirely real name system. The core problem of the real name system is the government whether and how generality gets the dignity information from administrative counterpart. After the carding of the present real name system, we found there are such problems: it`s ambiguous that who has the ability to decide and carry out the reality name system, it`s ambiguous that how to carry out the real name system is ambiguous and the content of the real name system is ambiguous.By preliminary economics analysis, and checkout by the principle of reservation and the principle of law creating norm, we found it`s necessary and possible for government to generally get information from administrative counterpart. But this conclusion don not lead the other conclusion, which that generally getting information from administrative counterpart by the singly real name system is necessary and possible at present.Judging by the principle of necessity, we should replace the real name system with the personal credit system. Because as a "the identical effective "system, the later system just makes "the minimum encroaches "on the "individual rights" to administrative counterpart.What`s more, when generality getting information from administrative counterpart, government must insist that or having clear law basis, or not going against current laws. And government must ensure that the benefit which gets from the generality getting information from administrative counterpart is not smaller than the encroaches brought to the administrative counterpart. |
