Abstract
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 6.3441 hm2.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.

Keywords material flow;ecological footprint;impact, population, affluence and technology analysis (IPAT).
