CEI: a new indicator measuring City Commercial Credit Risk initiated in China

In this manuscript, a historical review and detailed introduction of CEI is included, followed by statistical studies. In particular, an independent statistical cross-check for the existing CEI-2012 is performed and significant factors that play the most in influential roles are discussed.
