Bi-Weekly Symposium No.456 was held on July 6th 2012. The topic was "Relations Between Demography and Economy " and the keynote speaker was Mr. Liang Jianzhang, co-founder and chairman of Ctrip.com. In his mind, innovation and entrepreneurship have a relationship with age and the age structure. Young people will lose energy in an aging society. The only-child policy is absurd and ridiculous because such a policy distorts the age structure: the proportion of the population in the younger age groups decreases and proportion of the elderly increases, and it would also seriously weaken the vigor of innovation and entrepreneurial energies.
