為了探討競租者能力異質性對於二維度競租活動的影響，本文參考 Faria etal.(2014)的二維度競租投入模型，同時依循過往異質性競租分析文獻的設定方式，建立一個存在競租者能力差異的二維度競租分析模型。不同於既有文獻關於：能力異質性擴大將會使得社會競租浪費水準下降的分析結果，本文發現在本文所建立的分析架構下，若政府政策租利彈性夠大，則兩位競租者間的競租能力差異擴大，將有可能會使社會整體競租浪費水準增加而非下降。

In order to explore the impact of rent-seekers' heterogeneity in ability on two-dimensional rent-seeking activities. By referring to the two-dimensional rent-seeking model in Faria et al. (2014) and the models of heterogeneity rentseeking. We construct a two-dimensional rent-seeking model with rent-seekers' heterogeneity in ability. Different from previous studies' finding about the increasing of rent-seekers' heterogeneity in ability will decrease social rentseeking effort. Our finding shows that when the elasticity of policy rent is high enough, the increasing of two rent-seekers' heterogeneity in ability may increase social overall rent-seeking effort.
