Abstract

This study aimed to analyze influencing factors to increase the wage differential between large enterprise and subcontracted small-medium enterprises by using panel data composed of 19 manufacturing industries for 16 years from 1999 to 2014. According to the results of analysis, in large enterprises the elasticity of substitution between the labor inputs and the subcontracted product supplies from small-medium enterprises was significantly less than 1. So, the increase in wages of workers of large enterprises, whose degree of employment protection was relatively high, seemed to increase the share of wage cost in total cost and was resulted to decrease the cost share of subcontracted product supplies significantly. This was interpreted to be able to exert a negative influence upon the price of subcontracted product supplies and the wages of workers in subcontracted small-medium enterprises, and, therefore, to increase the wage differentials between large enterprises and subcontracted small-medium enterprises. Furthermore, it was also found that the increases in the labor union participation rate at large enterprises and the openness rate of the industry concerned were contributing to make such effects much stronger significantly. In order to mitigate the wage differentials and the polarizing trend in labor market, we can suggest to establish a certain kind of flexible wage system and to introduce co-bargaining practices with the workers of subcontracted small-medium enterprises within large enterprises, and also for the workers of small-medium enterprises, to prepare new social systems to upgrade their human resources and job skills drastically.

이 연구는 1999~2014년의 16년간 19개 제조업 중분류 산업들의 패널 자료를 사용하여 위탁대기업과 협력중소기업 간의 임금격차 확대 영향요인을 분석하고자 하였다. 분석결과에 의하면, 위탁대기업의 노동투입과 협력중소기업 납품생산물 사이의 대체탄력성은 1보다 유의하게 작게 나타났는데, 고용보호 수준이 높은 위탁대기업 근로자들의 임금상승은 총비용에서 차지하는 임금비용점유율을 높이고 협력중소기업 납품생산물의 비용점유율을 감소시키는 결과를 초래하였다. 이는 결국 납품가격과 협력중소기업 근로자 임금에 음(-)의 영향을 미쳐 위탁대기업과 협력중소기업 간의 임금격차를 더욱 확대하는 결과로 해석될 수 있을 것이다. 또한, 위탁대기업 근로자들의 노동조합 가입 수준과 경제개방도의 상승 역시 이러한 효과를 확대하는 방향으로 작용하였다. 기업규모 간 임금격차 확대 완화와 노동시장 양극화 억제를 위해서는 대기업 수준에서의 유연한 임금체계 도입과 협력중소기업 근로자들과의 현실적인 공동교섭방안, 그리고 협력중소기업 근로자들을 위한 인재양성 및 직업능력개발의 획기적인 사회적 장치 구축노력을 제안하고 있다.
