本文建構-AK成長模型探討技術水準與環保意識的提升對環境品質與經濟成長的影響。本文將污染防治支出設定為資本性的，而非經常性的。此一設定不僅較以往的文獻更接近實際的情況，且使本文獲致以下簡潔明確的結論：污染處理技術的進步可同時提升環境品質與經濟成長；生產技術的進步雖可提升經濟成長率，但必須以環境品質惡化為代價；而社會大眾環保意識的提升，雖可改善環境品質，但不利於經濟成長；若生產技術與環保意識呈同比例的提升，則環境品質不變，但可提升經濟成長率；若環保意識相較於生產技術大幅提升，則可在經濟成長率維持不變的情況下，改善環境品質；若生產技術與污染處理技術呈同比例的提升，則前都所造成的效用水準的增加幅度大於後者。

　　　　　An AK growth model is constructed to investigate the effects of technology improvements and increased environmental care on environmental quality and economic growth. The economy accumulates capital goods which are used not only in production, but also in pollution control. The main conclusions are as follows. The progress in abatement technology cause the environmental quality to improve and the economic growth rate to rise. The progress in production technology raises the economic growth rate, but it degrades the environmental quality. The increase in environmental care causes the environmental quality to improve, but lowers the economic growth rate. If production technology and environmental care rise in the same proportion, the environmental quality does not change, but the economic growth rate can be raised. If the percentage rise in environmental care is much larger than that of production technology, the environmental quality can be improved, with the economic growth rate unaffected. The effect of progress in production technology on the utility level is larger than that of same proportional progress in abatement technology.
