한국 직종별 노동수요의 결정요인 분석

Since the late 1990s, the wage gap between workers and employment instability has occurred in various lev- els, including industry, education, job type, gender, corporate size and employment type, in the Korean labor market. Many recent studies have revealed the existence of a segmented labor market in Korea. Accordingly, la- bor by occupation was set as independent factors for professional workers with high education and professional qualifications and non-professional workers . Based on this, the Cobb-Daglas production function including output, globalization and technological progress was set as three factors (physical capital, simple labor and pro- fessionals) and exogenous factors. Here, by applying the cost theory, the labor demand estimation equation for each job type was induced and determinants analysis was conducted based on it. As a result of the estimation, the demand for simple labor was significantly affected by output and technologi- cal progress. On the other hand, it was not affected by the relative price of the production factor(, , ) and the globalization factor. Professional labor demand was significantly affected by the relative price of physical capital, output, globalization and technological progress. On the other hand, it was not affected by the relative wage of simple labor. It was also found that simple labor demand is more elastic than professionals, so it is more sensi- tive to economic fluctuations and there is a complementary factor relationship between physical capital and professionals. Accordingly, the following policy implications can be presented. First, simple labor jobs need a job security policy in response to unemployment caused by employment decline during the economic recession and crowded-out effect of employment due to technological progress. Second, it is necessary to reorganize the education system and foster human resources in response to the demand for professional labor due to the tech- nological progress and globalization.
