정규직과 비정규직의 생활만족도 패널분석 - 잠재성장모형을 중심으로

This study empirically analyzed the life satisfaction of standard and non-standard workers by integrating the Korea Welfare Panel data (2008~2012). First, as a result of the analysis of the difference and trends during the past five years, the life satisfaction of standard workers was analyzed to be significantly higher as compared to that of non-standard workers each year, and the gap was found to be the greatest during the period of economic recession(2008~2009). Second, the life satisfaction of standard workers was found to be higher as compared to that of non-standard workers even in the state that the variables affecting life satisfaction are controlled through the panel regression analysis, and especially, the employment stability variables were found to have a significant impact on non-standard workers only. This means that the employment type of non-standard workers itself have a negative impact on life satisfaction as well as wages and working conditions, and suggests that the employment instability of non-standard workers is severe as compared to that of standard workers. Third, as a result of the estimation for the change rate of standard workers and non-standard workers using a latent growth model, the life satisfaction of standard workers was significantly higher than that of non-standard workers, and this gap was found to be maintained for the past five years without a big change. Therefore, there is a need to strengthen the support for non-standard workers who are under relatively poor wage and working conditions and are vulnerable to external shocks, and to increase the employment stability to increase the life satisfaction of non-standard workers. In addition, as the employment type of non-standard workers itself has a negative impact on life satisfaction, there is a need to promote the shift from non-standard workers to standard workers as well as ultimately eliminating the discrimination over wages and working conditions ultimately.
