Regulation of phonic resembling goods " was 1994 promulgate by the State Council, it is administrative regulations, it sets " this byelaw applies to those who record record player of substantial tape, video tape, disc, laser and laser to inspect dish of enharmonic to resemble product to publish, the duplicate, entrance, wholesale, retail, government that rent and runs sexual kinescope to show ", tell from broad sense, the sound here includes program of Internet seeing and hearing to serve apparently like goods (in " byelaw " useful " etc " undertook pointing to acting), in " regulation of phonic resembling goods " the publication that does not have pair of sound to resemble product, issue, sell, the regulation that management enterprise must be state-owned company," service of program of Internet seeing and hearing administers a regulation increase such provision, have apparently violate go up the suspicion of a law.

音像制品治理条例》是1994年由国务院颁布的，是行政法规，它规定"本条例适用于录有内容的录音带、录像带、唱片、激光唱盘和激光视盘等音像制品的出版、复制、进口、批发、零售、出租和经营性录像放映的治理"，从广义上讲，这里的音像制品显然包括互联网视听节目服务(在《条例》中用"等"进行了指代)，在《音像制品治理条例》并没有对音像制品的出版、发行、出售、经营企业必须是国有企业的规定，《互联网视听节目服务治理规定》增加这样的规定，显然有违上位法之嫌疑。
