사내하청업체의 인력활용 방식이 생산성에 미치는 영향:조선업을 중심으로

Shipbuilding is a labor-intensive industry that requires a large number of skilled workers, but shipbuilders have been externalizing through multi-level subcontracting rather than developing skilled workers, and the proportion of foreign workers has expanded rapidly in recent years. This study empirically analyzes the relationship between the employment practices of in-house subcontractors and productivity. This study uses the perspectives of Davis-Blake and Uzzi(1993) and Nohe(2007) to analyze the costs and benefits of choosing between internalization and externalization of labor and their relation to productivity. The results show that the use of multi-level subcontracting reduces productivity, while the retention of skilled workers increases productivity. The proportion of foreign workers, which has increased sharply in recent years, was not statistically significant in relation to productivity. There is no significant relationship between the level of wages and benefits of in-house subcontractor and productivity, but the level of payroll(wages, four major insurances, severance pay, etc.) management is positively related to productivity. On the other hand, the rate of increase in subcontract payments(progress payments), which is the source of available resources for in-house subcontractors, was positively related to productivity.
