Hanoi, the capital city of Vietnam, has been growing rapidly for several decades.
Most of world cities’ well-known social problems also occur in Hanoi. In line with the reform
of the society – social change is an unceasing process. However, it seems that the change
process in Asian countries is not continuous, but leapfrogging. Due to several beneficial
functions, urban green areas (UGAs) should play a central role in urban planning, particularly
in inner cities. Nonetheless, Hanoi citizens are not used to petition for social-welfare
infrastructure, for UGAs in particular. Therefore, a hypothesis is that Hanoi citizens will
demand more public parks. To check this hypothesis, triangular methods were set up in this
study, which include literature review, empirical study and observation. Some main factors of
changing lifestyles, those most influential to lifestyles of people in the usage of UGAs,
namely age, gender, geographical factors and mentality, are chosen to analyse. Some essential
evidences were found that Hanoians’ lifestyles will change to use more public parks. Our
findings also provide plausible proofs supporting that Hanoi citizen will ask for more parks
strenuously.
