The marketing dynamic capabilities (MDCs) are the specific form of dynamic capabilities on the marketing domain. Studies on the connotation and dimensions are inadequate. This paper explores the concept and scale development of the MDCs by means of mixed methods. This paper traces the theoretical origin of the MDCs, and then defines its connotation. Then, the researcher develops MDCs scale by means of content analysis and exploratory factor analysis. Finally, this paper, on the basis of empirical data collected from 327 firms, tests the reliability and validity of the scale. The results show that the three factors extracted fit well with the concept model, and then the MDCs scale consists of three dimensions: market cognizance competence, interface coordination competence and consumer response competence. The conclusions provide directions for firms cultivating MDCs, and lay the tool foundation for further empirical researches.
