| 中文摘要: |
| 聚焦山东省规模以上工业中小企业竞争力的动态评价，从创新投入与基础、创新产出与市场转化、资产运营三维度构建包含18项指标的评价体系。运用主成分分析法提取上述3个核心维度，累计方差贡献率达85.32%;引入时间衰减权重构建动态评价模型，适应数据结构变化的特点。实证表明，2021—2023年山东省中小企业竞争力呈现“累积式提升、近期驱动”的特征，该阶段的贡献突出。研究发现，创新资源投入与市场转化能力是竞争力的核心驱动，成长性与运营效率构成可持续发展基础。构建的评价框架可为区域评估和政策制定提供参考与实证依据。 |
| 英文摘要: |
| Focusing on the dynamic evaluation of competitiveness among industrial SMEs above designated size in Shandong Province, this study constructs an evaluation system comprising 18 indicators across three dimensions: innovation input and foundation, innovation output and market conversion, and asset operation. Principal component analysis extracts three core dimensions, accounting for 85.32% of cumulative variance. A dynamic evaluation model incorporating time-decay weights is developed to adapt to evolving data structures. Empirical evidence reveals that the competitiveness of Shandong’s SMEs exhibits a pattern of “cumulative enhancement driven by recent factors, ” with particularly significant contributions observed from 2021 to 2023. The study identifies innovation resource investment and market conversion capabilities as the core drivers of competitiveness, while growth potential and operational efficiency form the foundation for sustainable development. The established evaluation framework provides reference and empirical support for regional assessments and policy formulation. |
