創新的議題近年來在經濟發展的過程中，佔有越來越重要的地位，因為創新的能力影響了企業與國家的競爭力，在全球化的競爭中，各國無不努力提升創新的能力，以提高國際競爭力。自行研發與技術購買是企業的兩個主要技術來源，本文藉由分析新近的統計資料，以瞭解研發與技術購買的關係，是維持過去文獻所提出的互補關係，或兩者關係已產生變化，以瞭解台灣是否逐漸減少對外來技術的依賴，並邁向技術自主，成為技術輸出國家。 本文以2006年中華民國工商業普查製造業抽查所得的13098筆資料為樣本，先以OLS對樣本資料加以估計，之後考量樣本資料受限的特性，再以Tobit model進行估計，最後考量研發與技術購買的相關性，以SURE模型進行估計，得到的結果是台灣廠商在經過多年研發努力與成果累積之後，研發與技術購買仍然維持互補的關係，這表示台灣仍然需要依賴外來的技術來源，尚未達到技術自主的目標，且研發支出產生的成果，仍然無法讓台灣企業減少對技術購買的依賴。 由估計結果也可得知，研發活動還會受到廠商的資本密集度、企業規模、出口比例，與員工訓練支出的影響，了解以上因素對研發的影響方向，政府可以擬訂合適的產業政策鼓勵企業從事研發活動，以達到創新與技術自主的目標。 ;The issure of innovation has more important position in the process of economic development.Because the ability of innovation affects the competitiveness of a country .In the global competition,every country is trying to raise the ability of innovaton in order to raise competitiveness.Development effort and purchase technology are main technology sources of the enterprise.This paper want to comfirm the relationship between development effort and purchase technology is remaining complementary relation or not,through the analysis of recent statistic data.We want to know whether the Taiwan′s enterprise are less to rely on imported technology,and toward technology independent. The paper base on the 2006 manufacturing census proceeds of 13098 pen data for sample,using OLS estimation and Tobit model,and SURE estimation method.We came to the conclusion,that is even after the development effort for many years,Taiwan′s enterprise were still dependent on purchase of technology,and has not yet reached the goal of technology independent. According to the results,we also know the research and development are affected by the capital intensity,enterprise-scale,the proportion of exports,and the training of employee.Since we know the impact to the research and development,maybe the goverment can provide more effective policy to help enterprise to raise the ability of R&D.
