기술등급(T등급)에 따른 혁신 중소기업의 고용효과 개선에 대한 생존 분석

The purpose of this study is to analyze the relationship between innovation and improvement in employment effects by using the technology grade (T grade) that appraises the level of innovation from the perspectives of technology, business feasibility, and marketability. Survival analysis was applied to 115,804 SMEs eligible for technology-credit-loans (T1 to T6) to compare the probability and speed of improvement in employment effects. The employment effect was divided into the absolute employment effect based on the employment growth rate and the relative employment effect referring to the employment effect compare to sales. The improvement speed and improvement probability were calculated based on the point at which each employment effect improved by 72.8%. The working experience, number of employees, size, and industry operated at the time of appraisal were used as control variables. The analysis results confirmed that there was no significant difference in the absolute employment effect according to T grade. On the other hand, in the case of relative employment effects, it was confirmed that, within a limited range, the better the T grade, the greater the significant advantage in the probability of improvement in employment effects. Therefore, we concluded that innovation can create more jobs than sales, and the innovative SMEs have the potential to create jobs relatively continuously.
