传播学发展至今大体形成了三大研究学派:经验学派、批判学派、媒介技术学派。虽然这三大学派为传播学的繁荣发展作出了不可磨灭的贡献,但也使传播学陷入了前所未有的危机,现在急需一个平台将这三大学派的理论整合起来。本文认为,符号学可以成为这个整合平台,因为传播学三大学派都不同程度地用到了符号学的理论和方法。以符号学为平台整合传播学三大学派将使传播学逐渐走向传播符号学,这也是传播学走出困境的方向。 The development of communication has so far formed three major research schools: the school of experience, critical school, the school of media technology. Although these three schools have made an indelible contribution to the prosperity and development of communication studies, they have also thrown communication into an unprecedented crisis. There is an urgent need for a platform to integrate the theories of the three schools of thought. This paper argues that semiotics can become the platform of integration because the three schools of communication all use semiotics theories and methods in varying degrees. The integration of semiotics as a platform for the three major schools of communication will enable communication studies to gradually spread semiotics, which is also the direction of communication out of the woods.
