"The views expressed in the Ash Center Policy Briefs Series are those of the author(s) and do not necessarily reflect those of the John F. Kennedy School of Government or of Harvard Universi- ty" so okay, not really Havard's opinion or name behind the study

"While no single survey can adequately address all aspects of satisfaction levels in China, this brief identifies two important yet contrasting findings." Seems your own article disapproves of being used by itself to form opinions.

"Yet long-term, publicly-available, and nationally-representative surveys in mainland China are so rare that it is difficult to know how ordinary Chinese citizens feel about their government." Very insteresting "Although state censorship and propaganda are widespread" gotta love when your conclusion needs to mention this.

All in all no details for the actual methodology nor about the so called private company that perfomed the survey (since the institute apparently only created the survey itself).
