Is a Plea Really a Bargain? An Empirical Study of Six Cities in China

There is a belief in the criminal justice system that it is better to take a plea offer to avoid uncertain consequences than risk going to trial. Prior studies using the data in Anglo-American courts have suggested that many legal and extralegal factors influence the decision of a guilty plea versus trial. China developed its own plea-bargaining system in 2016. Using 6826 DUI cases adjudicated in six cities, this study examines what factors affect the decision of a guilty plea and whether the guilty plea brings true benefits in Chinese courts. The results show that more serious crimes and more dangerous defendants were less likely to be disposed of through guilty pleas (as opposed to going to trial). One possible explanation is that prosecutors may make more punitive offers in these cases, which in turn discourages defendants from accepting them. In addition, using a propensity score weighting technique to control for potential confounding variables, this study finds that defendants who pleaded guilty were more likely to receive favorable case outcomes regarding pretrial detention and probation decision, which supports the argument that a guilty plea could help a defendant to avoid the "trial penalty" in Chinese criminal justice system.
