Research on the Construction of a Multi-Format Integrated Management System for Small, Medium and Micro-Sized Enterprises

Small, medium and micro-sized enterprises (SMMEs) account for 99.8% of market entities in China and serve as the core force for macroeconomic stability. Affected by uncertainties in the external environment, 68.3% of SMMEs adopt multi-format operation to diversify risks, yet they generally face dilemmas such as fragmented management and data silos, resulting in significant losses in operational efficiency and restricting high-quality development. Existing research on integrated management mostly focuses on large enterprises, ignoring the asset-light and highly flexible characteristics of SMMEs, lacking a global integration framework and rigorous quantitative testing, and thus having insufficient practical adaptability. Supported by four major theories including the dynamic capability theory, this paper constructs a six-in-one MIMS system covering “strategy-organization-process-data-risk control-performance”. Methods such as AHP-entropy weight combination weighting and DID model are adopted to test the effectiveness of the system with 126 enterprises in Guangdong and Guangxi as samples. The results show that MIMS can increase operational efficiency by 37.2%, reduce management costs by 28.6%, improve capital turnover rate by 31.5%, and lower compliance risks by 62.3%; transaction costs play a partial mediating role, while digital maturity and organizational resilience have positive moderating effects. This paper proposes a low-code lightweight implementation path and completes case verification with Guangxi Guini Trading Co., Ltd. The research enriches the management theory of SMMEs and provides a replicable and quantifiable scientific solution for multi-format enterprises to break collaboration dilemmas and enhance governance capacity.
