This study analyzes the effects of innovation and innovation characteristics on the survival of Small and Medium-sized Enterprises (SMEs) in the service industry. After analyzing around 22,300 innovative SMEs in Korea's service industry using Kaplan-Meier analysis, it is confirmed that the better the overall technological prowess (T-grade), the longer the survival period until delinquency (overdue payments for more than three months) and default. The technological innovation characteristics that significantly affect the survival period are derived using a time-dependent Cox model. Owner capability, productization capability, and profit prospects are found to positively affect the survival period of excellent SMEs, while R&D capability, technology superiority, and market status are found to have a negative effect. From an optimization perspective, if R&D capability is above an appropriate level, it can hinder the survival period of SMEs. Thus, it is interpreted that the more positive the market status, the more negative the survival period, because it accelerates the inflow of new competitors. Considering that owner capability, productization capability, and profit prospects are appraisal items based on business feasibility along with the technological prowess of SMEs, it is concluded that technology with business feasibility has a significantly positive effect on the survival period of innovative SMEs in the service industry.

本研究分析了创新和创新特征对服务业中小企业生存的影响。使用Kaplan-Meier分析法对韩国服务业约22,300家创新型中小企业进行分析后发现，整体技术实力（T级）越好，拖欠（逾期付款超过三个月）和违约之前的生存期越长。使用时间相关的 Cox 模型得出显着影响生存期的技术创新特征。研究发现，所有者能力、产品化能力和盈利前景对优秀中小企业的生存期限具有正向影响，而研发能力、技术优势和市场地位则具有负向影响。从最优化的角度来看，如果研发能力超过适当水平，就会阻碍中小企业的生存期。因此，可以解释为，市场地位越积极，生存期越消极，因为它加速了新竞争者的流入。考虑到业主能力、产品化能力、盈利前景与中小企业的技术实力一样，都是基于商业可行性的评价项目，得出具有商业可行性的技术对服务业创新型中小企业的生存期具有显着的正向影响。 。因为它加速了新竞争对手的流入。考虑到业主能力、产品化能力、盈利前景与中小企业的技术实力一样，都是基于商业可行性的评价项目，得出具有商业可行性的技术对服务业创新型中小企业的生存期具有显着的正向影响。 。因为它加速了新竞争对手的流入。考虑到业主能力、产品化能力、盈利前景与中小企业的技术实力一样，都是基于商业可行性的评价项目，得出具有商业可行性的技术对服务业创新型中小企业的生存期具有显着的正向影响。 。
