;Since the development of electronics and high-tech industries in 1980s, the manufacturing and production technology, industry development and information society progress have all reached a mature state. Meanwhile, information and communication product was still subject to the limit of Moore’s law, the popularity and usage of information and communication product for the citizen of this country was in the top rank of the world. In a survey report of digital opportunity for individual and household as announced in 2014 by National Development Council of the Executive Yuan, the proportion of the access of smartphone and mobile network for citizen above 12 years old was as high as 94.6% and 91.5% respectively, while at such high information penetration rate, although the convenience of work and life had been greatly enhanced, yet negative influence might accompany. Therefore, three research topics were conducted in this paper based on information access behavior. First, the usage value of the third generation mobile communication technology in Taiwan was conducted with value analysis; next, the single-way and dual way e-learning behavior conducted by Taiwan’s people was analyzed; finally, correlation analysis will be conducted on internet community, instant messaging and digital anxiety behavior in Taiwan.
In the 3G usage value analysis of the first part, focus will be put on the decision factors, usage value and the value of its digital divide of Taiwan’s consumers in different 3G service development stages, meanwhile, a comparison will be conducted with the usage of broadband service. After using propensity score matching method to do the analysis, it was found that the usage decision factor characteristic of 3G growth period in 2009 was consistent with that of 3G mature period in 2014, meanwhile, it was totally different than the usage decision factor of broadband service. The usage value in 3G growth period in 2009 was 118.189 NT dollars, but in 3G mature period in 2014, it rose to 617.669 NT dollars. Moreover, the digital divide of usage value only existed in the 3G mature period in 2014, which was about 50.029 NT dollars, however, there was a little bit empirical result difference between metropolitan area and non-metropolitan area.
In the e-learning behavior analysis of Taiwan’s people of the second part, the main research targets were based on four perspectives such as individual feature, information access feature, individual network feature and individual local feature to study and analyze the decision factors when Taiwan’s people were conducting single-way and dual-way e-learning behavior, meanwhile, the learning performance of people after single-way and dual-way e-learning was also estimated. In addition, based on the sample, people were divided into student group and non-student group to inspect people’s e-learning behavior under different identity. After estimation using multi-selection handling effect model, it was found that the feature combination of decision factor between single-way and dual-way e-learning existed pretty large difference, and such difference also existed in the empirical result of the student and non-student people, moreover, the e-learning performance of single-way e-learning behavior was higher than that of dual-way e-learning behavior, meanwhile, the e-learning performance of non-student people was quite different than that of the student group.
Finally, in the discussion of digital anxiety behavior, the decision factors of Taiwan’s people using internet community and instant messaging service was analyzed first so as to estimate the correlation between people’s usage frequency of internet community and instant messaging service and digital anxiety. After using propensity score matching method for analysis, the empirical result showed that the main decision factors were low age, female, high education level, metropolitan area, highly mobile information and communication tool and network, high internet value recognition and people’s feature of longer years of contact with internet, once they have used internet community and instant messaging service, about 15.3~15.7% of formation probability of digital anxiety will be induced.
Generally speaking, in three information access topics as conducted in this paper, people will be expanded for their access to digital related application services (such as application services of single-way and dual-way e-learning, internet community and instant messaging service) due to higher internet usage value, great enhancement of the adoption of new generation communication technology and through the usage of information and communication technology (such as 3G technology). In addition, in the process of access of digital related application service, people will spend large amount of time in online network world, consequently, internet addiction and digital anxiety will be formed. The development of information access behavior and its application service was mature and diversified today, although this paper cannot cover all the information access topics, yet it had pointed out the positive and negative impact the information access behavior might generate on human society. The objective of conducting these three topics, in addition to the above motives, can also supplement the shortage of research literature presently.
