2012年以后的数据是否有误？为何前后差了这么多？

应该是要除以10的，不过最好还是要去透明国际官网核实一下http://www.transparency.org/

Transparency International
emphasizes: “Following a rigorous review process, some important changes have been made
to the methodology in 2012. The method we use to aggregate different data sources has been
simplified and also now includes just one year’s data from each data source. Crucially, this
method will allow us to compare scores over time, which was not methodologically possible
previously. Given the changes to the methodology, it must be emphasized that country scores
of the CPI 2012 cannot be compared against those of 2011 or previous editions. Year to year
comparisons will be possible from 2012 onwards” (Transparency International, 2012, p.1).
