| Summary: | 博士 === 國立清華大學 === 經濟學系 === 105 === Taiwan has gone through a vast industrial transformation. To reflect the impacts of innovation on firm's performance, in chapter 1 we adopt a modified CDM (Crepon et al., 1998) model to solve the selection bias and endogeneity problem among R&D, innovation and productivity, and focus on the innovation activities of Taiwanese manufacturing firms, especially on the comparison between OEM and non-OEM. Our findings suggest that considering the whole sample, only process innovation will improve both TFP growth and labor productivity growth. However, there exists a complementary relationship between product and process innovation on productivity only among OEM.
Taiwanese industries have started outward foreign investment since 1959, and the government has deregulated the investment to China since 1990. By the end of 2013, the accumulated investment to China surpassed the amount of outward investment (China excluded). However, the average unemployment rate has been rising steadily after 1995. In chapter 2, we adopt Taiwanese firm level data from 2008 to 2012 to examine the effects of outward investment on employment, and whether outward investment causes different impacts on managerial staff and R&D employees. Our findings show that investment in China will significantly decrease the domestic employment, but it will increase the employment of domestic manager. However, the effects of investment on R&D employee and service sector are not significant.
Many Taiwanese manufacturing firms choose employment downsizing to survive the financial crisis in 2008, while some companies choose to adjust their R&D investment plans. The aim of chapter 3 is to realize how a firm generates its employment and R&D strategies, especially when facing market uncertainties, and how these strategies affect its productivity or profits. We first use correlated random effect to find out the determinants of a firm's employment and R&D decisions. Then we adopt first order stochastic dominance test to compare the firm's performance distributions. At the final stage, we use traditional OLS to estimate the productivity premium model. Our results show that financial crisis does significantly decrease labor employment and have positive impacts on R&D intensity. However, only increasing labor employment during the financial crisis significantly improves a firm's TFP and sales.
