In this essay, the first aim is to apply the structure of material flow analysis (MFA) and ecological footprint
model to construct an environmental stress indicator. Secondly, an impact, population, affluence and
technology (IPAT) analysis is used to resolve indicators related to MFA and resource yield productivity. The
research indicates following results: (1) The 2007 per capita ecological deficit in Taiwan is 6.3441hm2
.The
figures reflect that productivity and life intensity of residents have exceeded the carrying capacity of Taiwan’s
ecological economic system. (2) Wealth becomes the most important factor in material needs and pollution
discharge. (3) Environmental efficiency and ecological efficiency slowed down dramatically, demonstrating
that use of resources and total amount of environmental stress stay at a developmental stage. Therefore, if
proper measures are not adopted, the current weak sustainability will lead into the vicious circle which departs
from sustainable development.
