The Internet has not had a great effect on the school performance of China's youth, according to a survey published last week. Nor has it affected the time children spend with their families.
The survey of over 3,000 students aged 10 to 18 in seven major cities was conducted by the Academy of Social Sciences. It showed that 29 per cent of students find the Internet useful for study. While over 40 per cent say it does not negatively affect their work.
The Internet does not cause social isolation either. Instead, Internet users are more satisfied with their lives and feel less lonely than non-users. In spite of the survey results, some youth workers still have concerns about cyberspace, especially the sex and violence it exposes young people to.
"Online gaming means many college students are stopped from studying, and some of them lose the chance to go to the school they want to," said Sun Yunxiao, vice director of the China Youth Research Centre.
