6792我国媒体产业呈现双轨制特色，产业中同时存在政策导向媒体与市场导向媒体。两类媒体的功能定位与激励机制迥然不同，使得两者对资本市场的影响存在差异。文章发现，在资本市场上，媒体主要通过负面报道，促进公司特质性信息反映在股价中，而正面报道则无此作用。在区分政策导向媒体和市场导向媒体后，文章进一步发现，媒体对资本市场信息整合的影响主要体现在政策导向媒体上，市场导向媒体则无显著影响。为了考察这种差异产生的原因，文章对两类媒体在资讯报道方面的文本特征（信息挖掘与信息传递）进行了比较，发现政策导向媒体相对于市场导向媒体进行了更深层次的信息挖掘与更精准的信息传递，这是它对资本市场信息整合更具影响力的真正原因。
