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.

摘要： SNM理论是基于演化经济学和技术系统论基础上建立的有关技术生态位和技术演化的分析方法，通过从微观到宏观进路的经验描述，初步建立了技术演化模型。本研究通过分析典型的数码化图像显示LCD和CCD技术的不同演化进路，论证SNM理论分析方法的实用性和可行性。该理论在技术论或STS领域，尤其是在讨论技术范式变迁和技术进化问题中，需要明确其讨论的方向和内容。同时，作为经验描述的分析方法，SNM理论有待进一步实证研究并拓展其理论运用的空间。
