기술투자등급(TI등급)에 따른 혁신 중소기업의 고용효과 개선에 대한 생존 분석

The purpose of this study is to verify whether the technology-investment grade (TI grade), which is designed to achieve financial performance, can be expanded and applied to employment effects. To this end, we compared and analyzed the probability and speed of improvement in employment effects according to TI grade of 2,300 technology-investment adequate firms (TI grade 1 to TI grade 6). The employment effect was divided into the absolute employment effect (employment growth rate) and the relative employment effect (sales employment coefficient) to allow for consideration of the diminishing phenomenon growth potential due to an increase in working experience. Improvement in employment effect was defined as the point at which the absolute and relative employment effect improved by 72.8% compared to the appraisal point. The survival period estimation results for the improvement in employment effect showed that both absolute and relative employment effects improved faster as the technology-investment grade (TI grade) was higher. As a result of confirming the improvement probability and improvement speed of the employment effect according to the technology-investment grade (TI grade) through a time-dependent Cox model with control variables applied, it was found that the higher the technology-investment grade (TI grade), the higher improvement probability of the absolute and relative employment effect at a significantly higher level. Therefore, the current technology-investment grade (TI grade) system can be expanded and applied to employment effects (absolute and relative), and it also provides implications for designing employment policies based on innovation.
