Abstract
Because information technology and knowledge economic is coming, digital divide become an important issue in the world. In the past, most of researches were focus on single time like specific year or some variables like age, income etc. They didn’t use the cluster of data systematic or use cross-time analysis. So this research separates the Taiwan family from family life cycle and social class. The standard of digital divide is that computer and internet have or have not. I investigate the influence of different family life cycle and different social class on the digital divide in the Taiwan family. Otherwise, I combine family life cycle and social class to separate the family and use cross-time analysis to observe the situation and change of digital divide in Taiwan. I hope the result of this research will help the government to implement the policy about digital divide and provide a good point on marketing. The results are following: (1)The own rate of computer or internet has difference in early stage and the trend will continue to follow digital equipments diffusion. (2)Every method to separate the family is effective in the stage of digital equipment be use more popular. (3)That effect of combine family life cycle and social class is the most powerful.
