다국어 초록 (Multilingual Abstract)

This study analyzes the effects of diversification on business results and enterprise values of KOSDAQ-listed venture companies to inquire into the effective diversification strategies of venture companies after an initial public offering (IPO). In particular, this study used the Berry-Herfindahl index as a proxy variable regarding the level of diversification of venture companies, and categorized the diversification methods into M&As, strategic partnerships and establishment of subsidiaries to analyze the effects of the mutual interaction among such methods. The following is a summary of the results of the analysis. First, diversification did not have any statistically significant effects on business growth. However, it was found that there was an inverted U-shaped relationship between diversification and the profitability of the company. Second, although no statistical significance was found between enterprise values measured based on diversification and market value, a U-shaped relationship or positive relationship was found. Third, M&As were found to moderate the relationship between diversification and business results and enterprise values. Fourth, strategic relationship and establishment of subsidiaries was found to moderate the relationship between diversification and the profit results of the company. Based on the above findings, this study discovered the practical implications regarding the diversification of venture companies after listing on the KOSDAQ.
