Abstract: SNM theory is an analysis method for technological niche and evolution which established according to the evolutionary economics and the systematic theory of technology. Through the micro and macro empirical description, SNM theory has set up the preliminary model about evolution of technology. The paper validated the SNM theoretical analysis method's feasibility and practicality from the analysis on the typical Digital Image Display of LCD and CCD Technology, and their different evolutionary trajectories. In discussing the transition of technological paradigm and technological evolution on the Study of Technology or STS research, the SNM theory especially needs to pinpoint the direction of the discussion and contents. At the same time, as a description of the experiences the analysis method the SNM theory needs further empirical research and expands its theoretical application space.
