| Nowadays,people live in a space of accelerating internal connectivity,which is full of complex cultural transformation,geopolitical impact and structural adjustment of modern society.How to clarify the continuously open and uncertain spatial logic has become an important field of communication studies and theoretical exploration of many humanities disciplines.This study takes Lefebvre’s spatial tripartitic dialectics and Habermas’ s research principle on the legitimacy crisis of late capitalism as theoretical tools,takes space availability as research object,discusses the realization category of Lefebvre’s spatial media view and the spatial perspective turning of the supply theory.While constructing a research framework for space availability,The paper explains the reality reflection and value innovation brought by the evolution of media technology for Lefebvre’s space production theory,which provides a logical path for the spatial turn of communication research and the development of global space theory.This study focuses on constructing an analytical framework of space availability from three dimensions of space production,space boundary and space subject,and expounds the mutual construction relationship among the three and their respective realization connotation.In the perspective of technological change,it presents the characteristics of dialectical,historical,anti-dualism and decentralized theoretical speculation.By combing relevant literature,this study finds that there is no unified definition of the term "spatial availability" in the academic circle,and most of the term is discussed as the spatial representation of the availability of media(technology).By examining from the perspective of spatial ontology,blind spots in the discussion of media technology and the research path of spatial media theory can be explored.The research background of space availability involved in this research is based on Lefebvre’s concept of space media,with a certain degree of criticism of political economy.It is to consider the possibility of space in the background of space production and capital criticism,and grasp the orientation of space availability research from the three perspectives of space production,space boundary and space subject.Specifically,the availability of space production follows the action track of the linear space theory,and tries to examine the construction relationship between space and capital multiplication,bureaucracy solidification and emotional integration from the perspective of communication political economy.The availability of space boundary reflects on the generalization of the boundary ontology under the technological change and reconsiders the action domain of Lefebvre’s space tripartite dialectics.The introduction of time dimension to observe the construction of space boundary explains the interpretation path of media evolution logic,and verifies the action logic of space and time mutual construction.The availability of space subject explains the reflexivity of technology and the reconstruction of space subjectivity,which requires people to pay attention to the various representations of subjectivity under the binding of objects.At the same time,it induces the value discussion of Heidegger’s "Dasei" concept and object subjectivity.The availability of space can be regarded as a breakthrough point in the discussion of space turning in communication studies.In addition to Lefebvre’s theoretical perspective,Husserl’s spatial localization and intentionality,Merleau Ponty’s spatial phenomenology,Deleuze’s tucking subspace and other views can be included in the category of spatial turning of communication studies.The discussion of space availability should not be limited to the critical study of column.In the future research on space availability,on the one hand,we should try our best to break through the loss of space subjectivity caused by mediatization and panmedia theory,on the other hand,we should also pay attention to the inherent symptoms of space ontology,explore the interactive relationship between structured and unstructured space,and then provide empirical coordinates for the spatial transformation of communication studies. |
