本文通过logit模型考察媒体关于上市公司违规行为的报道是否会促使上市公司改正其违规行为。本文构建上市公司治理行为指数,对上市公司的治理水平以客观指标进行评价,以治理行为指数为被解释变量,考察媒体对违规行为的报道对治理行为指数的影响。模型实证的结果为:媒体的负面报道能够约束经理人和控股股东的行为,即:媒体监督是有效的。 This paper examines whether the media coverage of the listed companies’ violations through a logit model will prompt the listed companies to correct their irregularities. This article constructs the governance behavior index of listed companies, evaluates the governance level of listed companies with objective indicators, and uses the governance behavior index as the explanatory variable to examine the influence of media coverage on governance behavior index. The empirical results of the model are as follows: negative media coverage can constrain the behavior of managers and controlling shareholders, that is: media supervision is effective.
