摘要

本文使用1984-2001年收集上市上櫃的財務和參與科專計畫等資料，共收集7560筆廠商年度(firm-year)資料，依照一般文獻的做法，分別使用單一方程式迴歸估計及聯立方程式兩階段估計法，並且使用Tobit模型及Negative Binomial模型來探討在不同領域的科專計畫下，參與科專計畫廠商與其研發支出間的關係。

本文的主要發現如下：
1•中小企業參與科專計畫的程度及研發支出密集度較大企業的小。
2•不同產業的中小企業在參與科專計畫的程度及研發支出密集度上
的表現皆不相同。
3•在單一方程式迴歸結果發現廠商參與科專計畫和其研發支出間具
有因果關係，但在二階段迴歸結果卻發現這兩者並不具有完全的因果關係。

In this thesis, 7,560 firm-year observations about firm’s financial information and the information of firms participated in S&T projects are collected from TEJ database and MOEA respectively. According to the literature, we used single-equation regression and simultaneous equations regression with Tobit model and Negative Binomial model discussing the relationship between the intensity of participation of S&T projects and firm’s R&D expenditure.

The main findings of this thesis:
(1)Both the intensity of participation of S&T projects and firm’s R&D expenditure of SMEs are smaller than that of large enterprises.
(2)Both the intensity of participation of S&T projects and firm’s R&D expenditure of SMEs within different industries are not indentical.
(3)There exists the causality correlation between the intensity of participation of S&T projects and firm’s R&D expenditure in single-equation regression but it does not exist under the introduction of simultaneous equations regression.
