本文在中間商品市場不完全競爭的架構下，探討仿冒稽查、對中間要素補貼及對中間財廠商課徵銷售稅等政策，如何影響中間財廠商的創新與仿冒決策，以及其對工資與經濟成長的影響。我們發現，較嚴格的仿冒稽查政策，會降低產品擴展率，而不利經濟成長，但對工資的影響不確定。此外，對中間要素補貼或對中間財廠商課稅均會降低產品擴展率而不利於經濟成長，然而，對中間要素補貼會使得工資上漲，但對中間財廠商課稅卻使得工資下降。 This paper explores how the imitation detection and tax (or subsidy) policies affect the innovation, imitation and economic growth. We find that the severer patent protection and the production subsidy and sales tax on intermediate firms decrease the profit in research sector, further, lead to a lower rate of innovation and retard economic growth. On the other hand, we show these policies effect on wage rate. The patent protection policy has ambiguous effect on wage rate. The production subsidy raises the wage rate whereas the sales tax has negative effect on that.
