초록

As the development of the knowledge, technology and information for the industrial development was deepened, the securement of the workforce has been regarded as an important factor for firm's growth. Especially, the importance of skilled workers who can make full use of technology and knowledge is becoming larger. That is, the securement of the skilled workers has been considered an important factor for corporation's growth. In this respect, the shortage of industrial technology workforce also has been considered an major factor restricting corporations' competitiveness and performance. This thesis has analyzed the effect of the industrial technology workforce shortage on a corporation's performance based on panel data constructed by combining those of Korea Enterprise Data and the Ministry of Knowledge Economy data. Methodologically, in order to resolve the problem of selection bias the Propensity Score Matching using the Nearest Neighbor Matching has been applied to estimate the average treatment effect on the treated (ATT) of the shortage on a corporation's performance. Furthermore, the effect of the level of skills and the level of technology of the corporation on a performance has been examined. Upon the analysis, the shortage of industrial technology workforce displayed to have negative effects on both the technological as well as financial aspects, and the shortage appeared to have heterogeneity and threshold effect. That is, the effect of the shortage applied to mid- to high-tech groups than low-tech corporates, and the shortage of bachelor degrees appeared to have a greater effect. Therefore, government needs to consider the technology level of the firms when supporting the industrial technology workforce policy, and the current support program which is focusing to foster master's and doctorate degree also needs to be reconsidered.
