本文探討農業生物科技研發出低污染的農耕技術對農業生產、環境品質所產生的正面影響，提升農業永續經營的可能性。本文以內生成長模型為理論架構，探討對生物科技開發的低污染農耕技術給於補貼，提高它與現有的農耕技術競爭能力，並且使用定額稅融通補貼。我們發現租稅補貼政策會改善農業生產的環境污染，提高環境品質和長期農業生產力，增進經濟成長。本文也嘗試分析預料到的低污染農耕技術採用對經濟成長的短期和長期的動態效果，發現從宣告到全面使用該項新技術前，產出成長率是下降，直到新的農耕技術開始使用，產出成長率才會上升。

This paper explores the dynamics of the economic growth rate in the presence of an explicit link between the agricultural biotechnology and environmental protection in an endogenous growth model. The modeling strategy is that the government per-announce policy that imposes a lump-sum tax and the technology to the biotechnology development low pollution agriculture is being subsidized. Our find anticipated the taxes and subsidies will influence the steady-state economic growth rate and the short-run growth rate. We show that an increase in the steady-state economic growth rate is due to the expansion of biotechnology in a agricultural production technology has innovative technological change and improve quality of environment and the dynamics of the short-run growth rate results in the transitional behavior.
