本文欲探究廠商投資研發活動(R&D)和出口活動對於廠商生產力有何種的影響，所採用研究數據來自台灣經濟新報資料庫（Taiwan Economic Journal），時間選取跨度為2005年至2019年總共15個年度，對象為台灣上市上櫃的電子零組件製造業和電腦、電子產品及光學製品製造業廠商。本文選用Aw,J.Roberts and Daniel（2011）的模型為基礎架構，並以馬爾科夫進程討論廠商進行出口活動和研發活動的時候將如何影響其生產力，還將加入延伸分析，將廠商特性分為生產力高低、年齡大小、規模大小，以及廠商的研發活動報酬與出口之間的關係來進行探討。
本文的模型為理論推導和實證兩個部分，先利用中間財作為代理變數，再用最小平方估計法(OLS)估計廠商收入函數的係數。根據推導出的廠商生產力演化模型，使用非線性最小平方估計法(NLLS)估計廠商投資研發活動和出口活動對於生產力的影響。研究結果證實，廠商在本期不論投資研發活動或出口活動，都會對下一期廠商的生產力產生顯著正向的影響。

This paper intends to explore the impact of manufacturers invest in R&D activities and export activities on manufacturers' productivity. The research data are from the Taiwan Economic Journal, covering a total of 15 years from 2005 to 2019. The objects are Taiwan's listed electronic component manufacturing and computer Manufacturers of electronic products and optical products. This paper selects the model of AW, J. Roberts and Daniel (2011) as the basic framework, and uses Markov process to discuss how manufacturers' export activities and R&D activities will affect their productivity. It will also add extension analysis to divide manufacturers' characteristics into productivity, age and scale, and the relationship between R&D activity compensation and export.
The model in this paper consists of two parts: theoretical derivation and empirical analysis. Firstly, intermediate finance is used as the proxy variable, and then the ordinary least square estimation method (OLS) is used to estimate the coefficient of manufacturer's income function. According to the derived firm productivity evolution model, the nonlinear least square estimation method (NLLS) is used to estimate the impact of firm investment in R&D activities and export activities on productivity. The results show that whether manufacturers invest in R & D activities or export activities in this period will have a significant positive impact on the productivity of manufacturers in the next period.
