传媒产业结构性进入壁垒探析

规模经济、媒介产品的差异、一定的资源、必要的资金量等构成了传媒产业的结构性进入壁垒。结构性进入壁垒具有双重效应，可以维护在位媒介的利益，并形成规模效益；同时，它会排斥竞争机制、限制资源自由流动等。因此，应当辩证看待媒介产业的结构性进入壁垒。

On the Structural Entry Barriers of Media Industry

Structural entry barriers are composed of economies of scale,difference of media products,resource and necessary fund.Structural entry barriers have dual effect.On the one hand,it can preserve inside media and form economies of scale.On the other hand,it will reject competitive mechanism and restrict free mobility of resource and so on.So we should see structural entry barriers in dialectical attitudes.
