- Table 4 reports the mechanistic test results for Internet use. The dependent variable in columns (1) and (2) is the importance of using the Internet to obtain information (info), which measures the effect of health information acquisition. It is based on the question “How important is the Internet to your access to information?” The scale ranges from 1 to 5, where 1 indicates “very unimportant,” 2 indicates “relatively unimportant,” 3 indicates “average,” 4 indicates “relatively important,” and 5 indicates “very important.” The dependent variable in columns (3) and (4) is the weekly exercise time(hours) (exercise), which measures the healthy lifestyle of older adults. The dependent variables in columns (5) and (6) are social and recreation (social，recreation), which measure the level of social interaction, and they are measured on a scale of “importance of social and entertainment when using the Internet” And 1 represents “very unimportant,” 2 represents “relatively unimportant,” 3 represents “average,” 4 represents “relatively important,” and 5 represents “very important.” The key independent variable in (1), (3), (5) and (6) is the frequency of Internet use (frequency). The key independent variable in (2) and (4) is whether to use the Internet (Internet). All specifications include county and year fixed effects. Robust standard errors are clustered at the provincial level (robust standard errors in parentheses)
- *, ** and *** indicate significance at the 10%, 5%, and 1% levels, respectively
