公務員提供司法、教育與健康等公共服務，在一國經濟發展中扮演關鍵性的角色，然而回顧過去的相關文獻，對於公務人力與經濟成長間的關係，尚無法產生一致的結論，且目前並沒有相關實證文獻以台灣為研究對象，探討公務人力與經濟成長的關係。 本文以公務人力作為政府規模的衡量指標，採用1996年至2005年台灣地區23縣市的追蹤資料，由於使用固定效果模型時產生計量上問題，故改以處理混合資料為主的普通最小平方法進行實證估計。研究結果發現，地方政府規模對地區性經濟成長之影響，係隨規模的增加由正轉負，符合 Armey curve的非線性關係，亦即倒U型的曲線關係，也就是說，適當的政府規模對整體經濟有利，過小或過大的政府規模將會阻礙經濟發展。且因地方政府規模對地區性經濟成長之間存在倒U型的曲線關係，可發現能使地區性經濟成長率達最大化的地方政府最適公務人力規模為21.49，平均而言，台灣地方政府規模仍低於此一最適水準。 在本研究中亦發現，同時加入實證模型的其他解釋變數對於地區性經濟成長存在顯著的作用，包括了房屋稅收入、地價稅收入、土地增值稅收入結構比以及相對薪資率具有正向的刺激效果，而政府預算赤字以及人事費用的增加將不利於地區性經濟成長。 / The role of public employment is significantly important to the economic development because public employees are the only vivid resource of government to offer public service, such as justice、education and health etc. However existing researches about the expansion of public employment also have inconstant effect on economic growth. The Armey curve infers that the government size and economic growth have an inverse U shape, and that one can find the optimal government size that promotes the greatest economic growth rate. This study measures public employment as government size and employs the panel data and ordinary least squares regression model to test whether the Armey curve exists in the local government in Taiwan. The result indicates that a non-linear relationship of the Armey curve indeed exists in the local government in Taiwan. And the average size of the local government in Taiwan is smaller than the optional size that promotes the greatest regional economic growth rate.

1980年代起中國通過財政體制改革與「放權讓利」，促使各地方政府積極推動各項經濟發展事業，獲得非凡的成就。已有相關實證文獻主張政府規模與經濟成長兩者之間的關係為非單一線性關係，且兩者乃倒U型關係的論點，並在不同國家取得驗證。本研究試圖檢驗此現象是否亦存在於中國的地方政府。通過中國31個省市地區自1995至2005年的地區別資料，將地方政府規模變數之平方項納入實證模型並以two way固定效果模型進行估計，試圖捕捉到更全面性的中國地方政府規模與地區性經濟成長之關係。此外，中國財政體制至今仍未臻完善，特別是預算管理制度與世界先進國家仍有重大差異，本研究亦會針對此中國特殊國情詳加說明。 分類號：B23；C33；E62；H72 / / The purpose of this study is to investigate the inverse-U relations argument whether also exists between China local government size and the regional economic growth ever since fiscal reform was embarked upon and the budget act was embarked upon in 1994. By using of the China 31 province-level data from 1995 to 2005, this study establishes four empirical models with square item of the local government size as an independent variable and are estimated by two way fixed effect model which attempts to catch the relation more comprehensively between China local government size and the regional economic growth. This research empirical result shows that China's local government size has the positive effect on its regional economic growth, and actually the inverse-U relations (Armey-curve) exists between them. This confirms that the Armey-curve phenomenon also exists in a country's secondary government
