摘要

本文透過估計台灣非金屬礦物製品製造業之長、短期成本函數，探討其生產投入替代、技術變動偏向及規模經濟的情形。觀察根據估計結果計算所得之各種彈性值及分析數值，如價格彈性、Allell及Morishima替代彈性、產出彈性 … 等，使我們對非金屬礦物製品製造業過去二十餘年的生產情況有了更深入的瞭解。基本上，民國70至80年問是此一行業較為風光的年代，近年來則有投資不足、規模報酬遞減等現象，值得我們關注。

This paper analyzes input substitution, technical change bias, and economies of scale measures for the Taiwan nonmetal minerals industry. By estimating the short- and long-run variable cost functions of the industry, we calculated the price elasticities, Allen partial elasticities of substitution, Morishima elasticities of substitution, output elasticities, as well as the input bias of technical change and economies of scale measures for the industry. The results reveal that the 1980s have been the most prosper years for the nonmetal minerals industry. The underinvestment and decreasing returns to scale phenomena found in recent years, however, seem to signal the declining of the industry, which deserves our attention.
