This study is to examine the impact of organizational learning on affective commitment in Korea. In particular, this study addressed the importance of organizational learning as an HRD strategy from the socio-cognitive perspective. Data were collected from four large companies located in the area of Seoul, South Korea. There were 233 usable questionnaires yielding a response rate of 61%. Multiple regression analysis and principal factor analyses were applied to conduct a data analysis. The results showed that a linear relationship existed between the organizational learning capacity and affective commitment (R[superscript 2] = 0.495). Four dimensions were statistically significant with the exception of "feedback." Participative decision-making is the most important factor. Finally, the study discussed some implications for HRD theory and practice.
