My research interests are in the aging population, family change, and social policies.
During the 1990s, I have conducted a series of research on the population change in Taiwan
and its impacts on the national pension system; besides examining the development and
evolution of pension systems in Europe and America, proposing the Taiwanese model of
national pension system, and simulating how varying methods of finance management may
impact on the pension system, the studies discussed the potential and challenges of
increasing the retirement age to alleviate the financial pressure. Another point of interest is
in population and health, including the “birth quality” of foreign-born women in Taiwan, the
transition of elderly health conditions, and the illustration and elucidation of life tables, life
expectancy, and cost of care.

Every person’s place in the society does not stand alone from each other, but shares
living and finance with their family members. Therefore, the discussion of population
transition and social security systems should start from the angle of families. To explore the
future trend of family formation, I have started to investigate the dynamic shift of family
formation since 1997, interpreting the impacts of marriage rates, mortality rate, birth rates,
and occurrence rates of leaving parental home on family size and family structures. In the
process of research, I have noticed that the marriage rate in post-war Taiwan changed
rapidly, and that there is insufficient research on the trend. Thus, I have conducted a series of
research on marriage and family, including the estimation of cohabiting population, the
change of assortative mating model, the pace of marriage and fertility, and labor
participation of married women. The shared conclusion of these studies is that, in terms of
the two key factors of family formation, marriage and fertility, Taiwan retains firmly
traditional values.

Taiwan’s change in marriage and fertility echoes McDonald’s Gender Equality theory,
in that the gender equity in “family-oriented institutions” lags behind gender equity in
“individual-oriented institutions,” and thus resulting in the drop of marriage rates and
fertility rates. Therefore, my research lately focuses on “why the gender equity in “family-
oriented institutions” cannot catch up?,” “can Taiwan’s marriage and fertility rate rebound?,”
“if marriage rate does not rebound, how can we face the upcoming ‘single society’?.”
