A Multi-model Based Approach for Measuring Operational Efficiency in Smes: Theory Construction and Empirical Analysis

Small and medium-sized enterprises (SMEs) play a pivotal role in China's economy, but the issue of their operational efficiency has attracted much attention. This study aims to construct a method to measure the operational efficiency of SMEs based on DEA-PCA model. Through theoretical elaboration, model construction, indicator selection, empirical analysis, and result discussion, it reveals the characteristics and influencing factors of SMEs' operational efficiency, and provides theoretical basis and practical guidance for enterprises to improve their operational efficiency. The study shows that this method can effectively overcome the subjectivity of the traditional DEA method in the selection of indicators, and provide strong support for the accurate assessment of the operational efficiency of SMEs.
