2.4 System Dynamics
System Dynamics (SD) is a computer simulating
model created by Professor Jay Forrester of the
Massachusetts Institute of Technology in 1956. In
order to combine systematic analysis methodologies,
policy-making theory, information feedback control
theory and computer simulation technology as
the theoretical basis, its purpose is to simulate and
improve high-level, nonlinear and many circular
dynamic complex system. Because SD can effectively
solve the general calculating analysis model and the
uneasy quantifying variables in the dynamic situations
and other disadvantages. Therefore, the simulating
system can create a factual situation close to the real
environment (Tsai, Ya Hsiu, 2007)
2.5 Achievement of current sports policy operation
According to the survey and reports by in 2012 Sports
Administration in 2012, the regular-sports population
proportion has risen from 27.8% (2011) to 30.4%. In
2012, more than 28,000 people took part in cross-lake
swimming game at the Sun Moon Lake. Besides, more
than 120,000 people participated in Taipei Fubon
Marathon. Therefore, imposed in the rising sporting
atmosphere, more Taiwanese people start getting
involved in the challenging large-scale sports events.
2.6 Policies are to be improved
The development of emerging sports gives positive
meaning of people’s leisure demands. Apart from the
general and traditional sports. With the promotion of
mass media there are more abundant and entertaining.
However, the relevant regulations of high-risk sports and
counseling institutes are in a dire need to be established.
2.7 Taking the strategies abroad for reference
In 2010, the Japanese government announces a strategy
that sports as a nation’s foundation and would take it
as the base of the next-decade sports development
principle. Thus they can reach the target of sports
community. Moreover, in the UK policy, A Sporting
Habit for Life: 2012-2017, it emphasizes three concrete
targets to improve: 1). all people from elementary school,
junior and senior high school, colleges and universities
to workplace shall participate in sporting activities; 2).
Particularly, the young population from 14 to 25 years old
shall exercise once a week and this policy would try to
reduce the sports dropout of the people who are above
25 years old; 3). Encouraging adults to take part in sports.
