台灣的國民所得統計在103年採用聯合國2008年版國民經濟會計制度 (2008 SNA)，將研發支出從中間消費改列為固定資本，並歸類於智慧財產 (Intellectual Property Product, IPP) 項目。此修正說明過去對勞動份額的高估，因此本論文針對台灣1982-2022年間勞動份額的變化進行詳細分析，並探討IPP資本對勞動份額的影響。
本研究主要參考Koh and Santaeulalia-Llopis and Zheng (2016) 的文獻，將IPP資本納入總體生產函數中。利用1981-2022年的總體時間序列資料，應用兩資本模型的貝爾曼方程式，求出一階條件極大的最適資本總報酬率來估算資本份額，並探討IPP資本的提升對勞動份額下降的影響。研究結果顯示，台灣的資本使用量逐年上升的同時，總資本所得對勞動所得比率與傳統資本所得對勞動所得比率並非維持不變，證實台灣存在資本深化現象，台灣的IPP資本與勞動替代彈性和傳統資本與勞動替代彈性都顯著異於一。本研究證明，IPP資本深化顯著改變了資本與勞動之間的替代彈性，進而影響勞動份額的變化，這反映在台灣經濟中無形資產的重要性日益增加。
In 2014, Taiwan adopted the United Nations' 2008 System of National Accounts (2008 SNA), reclassifying RandD expenditures from intermediate consumption to fixed capital and categorizing them under Intellectual Property Products (IPP). This revision explains the past overestimation of the labor share. Therefore, this paper provides a detailed analysis of the changes in the labor share in Taiwan from 1982 to 2022 to examine the impact of IPP capital on the labor share.
The study primarily cites the paper of Koh, Santaeulalia-Llopis, and Zheng (2016) that put IPP capital into the aggregate production function. We use the time series data from 1981 to 2022, with the Bellman equation of the two-capital model. This helps derive the optimal rate of return on capital for estimating the capital share and explores the impact of increasing IPP capital on the decline in the labor share. The results show that while capital use in Taiwan has increased yearly, the ratio of aggregate capital income to labor income and the ratio of the traditional capital income to labor income do not remain constant, indicating there is capital deepening in Taiwan. Taiwan's elasticity of substitution between IPP capital and labor is significantly different from one. The elasticity of substitution between traditional capital and labor in Taiwan is also significantly different from one. This study demonstrates that IPP capital deepening significantly changes the elasticity of substitution between capital and labor, thereby affecting changes in the labor share, reflecting the increasing importance of intangible assets in the modern economy.
