經濟成長與環境品質：經濟系統與生態系統共生關係之研究

Abstract

This paper formulates a two-sector endogenous growth model by incorporating knowledge capital and environmental capital into account to investigate the interaction relationship between economic growth and environmental quality. The decision maker values both goods and environment consumption, and the important decision in this model is to decide the optimal allocation of knowledge capital and environmental capital across the sectors. It is through the interaction between the economic system and ecological system that generates fruitful results in understanding the relationship between economic growth and environmental quality. In this model there exists a long-run balanced growth path for both goods production and environmental quality. Moreover, a positive productivity shock of the goods sector is also beneficial to the environmental sector. Policy implications and a reconsideration of the concept of Green GNP are also discussed.
